Experts expand on the need for a comprehensive understanding of all sources of data in DCTs, and the need to evaluate those data centrally in real time to mitigate the risks associated with their capture (including data capture at the edge of the network (wearables)).
Every disruptive innovation must be complemented by adapted procedures, and this also applies to decentralized clinical trials (DCTs). Traditionally, sites entered clinical trial data in an Electronic Data Capture (EDC) system and these source data were verified at the site to confirm accuracy. Risk based monitoring focused on site level metrics such as screen failure rates, query rates, Serious Adverse Events (SAEs) reported, missed/late visits, etc. With DCTs, as source data are collected directly from participants this is no longer an option and a different approach is required to ensure the quality and integrity of the data. As a rule, a comprehensive understanding of all sources for data capture in a clinical trial and the process for centralization is essential. Also, it is important to evaluate the data collected in real time to allow early interventions that will ensure data integrity for regulatory submission.
In this webinar, Chitra Lele describes how centralized monitoring strategies can help aggregate and analyze data in real time and provide insights to a variety of functional teams across the trial continuum. Daniel Gutierrez describes how the Clinerion platform can boost data integrity in DCTs. The technology transforms global data sources to one query-able data model for structured medical data, while ensuring that the data keep its full resolution and integrity during aggregated queries.
Pierre Etienne talks about the expanding role of mobile Health Care Professionals (HCPs) and their crucial role in protecting data integrity. Clifton Chow finishes with a comparison of several artificial intelligence (AI) based binary classifiers for detecting the integrity of data obtained from Internet of Things (IoT) enabled wearable sensors.

A project with the aim to standardize an RBM approach in clinical trials. It unites four companies and academic organizations, focuses on the evaluation and optimization of Risk-based Monitoring (RbM). For this purpose, PUEKS will use data available from past clinical studies to select substantiated key risk indicators (KRIs). Subsequently, the obtained data-driven KRIs will be tested in an ongoing trial. A comparative evaluation with historical data from past studies will be additionally performed to evaluate the power of the selected KRIs in terms of cost savings, enhanced quality, and risk mitigation. The project is aimed at delivering a robust RbM tool as well as an optimized procedure for the successful implementation of RbM.
This project (HA project no. 448/14-38) is funded in the framework of Hessen ModellProjekte, financed with funds of LOEWE – Landes-Offensive zur Entwicklung Wissenschaftlich-ökonomischer Exzellenz, Förderlinie 3: KMU-Verbundvorhaben (State Offensive for the Development of Scientific and Economic Excellence).
Risk Based Monitoring in Clinical Trials.ClinosolIndia
Risk-based monitoring (RBM) is a monitoring strategy in clinical trials that aims to improve the quality and efficiency of data collection while reducing costs and burden on study participants. Rather than conducting monitoring activities at fixed intervals, RBM utilizes a risk assessment approach to identify areas of the study that are at higher risk of errors or deviations from the protocol and focuses monitoring efforts on those areas.
The RBM process begins with a risk assessment, which involves identifying potential risks to the study's data integrity, participant safety, and study conduct. This may include risks related to patient enrollment, data collection, adverse event reporting, or protocol compliance. Based on the risk assessment, the study team creates a risk management plan that outlines the monitoring strategy to be employed throughout the trial.
In RBM, monitoring activities are targeted to focus on the areas of the study that present the highest risk. For example, if a study has a high risk of data entry errors, the monitoring plan may include a more intensive review of data entry activities or require that data be entered in real-time, so errors can be identified and corrected more quickly.
RBM can be facilitated through several tools, such as centralized monitoring, key risk indicator (KRI) dashboards, or data analytics. Centralized monitoring allows for remote review of study data by a team of experts who can identify trends and issues more efficiently. KRIs are pre-defined metrics used to track performance and detect areas of concern, allowing for proactive management of risks. Data analytics can identify unusual patterns or outliers in the data, enabling the study team to focus on those areas of concern.
RBM is a dynamic process that involves ongoing evaluation of the study's risk profile and adjusting the monitoring strategy accordingly. By focusing monitoring efforts on the areas of the study that pose the highest risk, RBM can improve data quality and participant safety, while reducing monitoring costs and burden.

Exploring Predictive Biomarkers and ERK1/2 Phosphorylation: A New Horizon in ...InsideScientific
In this webinar, Dr. Victor Arrieta highlights the link between p-ERK activation and improved survival in rGBM patients using anti-PD-1 immunotherapy.
Recurrent glioblastoma (rGBM) has displayed a varied response to anti-PD-1 immunotherapy, necessitating the identification of predictive biomarkers. Through extensive analyses and 3 clinical studies, we have identified that activation of the MAPK/ERK signaling pathway, particularly ERK1/2 phosphorylation (p-ERK), is associated with longer overall survival (OS) in rGBM patients receiving PD-1 blockade. Initially, enrichment of BRAF/PTPN11 mutations was reported in 30% of responsive rGBM patients, prompting the investigation of p-ERK as a potential marker beyond these mutations.
Our research has unraveled an association between p-ERK abundance and better clinical outcomes following PD-1 blockade, with p-ERK mainly localized in tumor cells. Notably, high p-ERK GBMs contained unique microglia and macrophage phenotypes with elevated MHC class II expression, suggesting a novel interplay between MAPK activation and the tumor immune microenvironment.
While these insights establish a pivotal role for p-ERK in predicting PD-1 blockade response in rGBM, the implementation in clinical settings calls for further validation and accuracy. Nonetheless, these findings pave the way for more personalized and effective immunotherapy strategies, emphasizing the significance of the tumor microenvironment and its interaction with therapeutic interventions in GBM.
Key Topics Include:
- The activation of the MAPK signaling pathway, specifically ERK1/2 phosphorylation (p-ERK), is identified as a predictive biomarker for longer overall survival in recurrent glioblastoma (eGBM) patients undergoing PD-1 blockade
- High p-ERK tumors in rGBM present a distinct myeloid cell phenotype with elevated MHC class II expression, signifying a connection between MAPK pathway activation and the immune microenvironment
- The implementation of p-ERK as a predictive biomarker in clinical settings requires further validation and exploration of variables impacting its evaluation

In this webinar, we will provide a comprehensive overview of Artisan Bio’s STAR-CRISPR system, which is designed to improve the specificity and efficiency of gene editing for cell therapies. We will explain the system’s key components and how we are using a risk-based approach to optimize and validate the editing platform. The webinar will focus on Artisan Bio’s approach to building T cell OS/APPS through iterative improvements to achieve best-in-class editing capabilities and improved cell health metrics.
Key Topics Include:
- Learn about Artisan Bio’s proprietary high-performance STAR-CRISPR system for improving the specificity and efficiency of gene editing for cell therapies
- Explore Artisan Bio’s risk-based, systems approach to technology development, including how to implement Design of Experiments (DoE) and Quality by Design (QbD) principles to optimize and validate any process
- Case study of the application of QbD to Artisan Bio’s STAR-CRISPR platform to edit T cells for cancer immunotherapy with preliminary data showing improved efficacy, expansion, and functionality
Peripheral and Cerebral Vascular Responses Following High-Intensity Interval ...InsideScientific
Dr. Bert Bond and Max Weston will present an overview on their study investigating the effects high-intensity interval exercise has on cerebrovascular health.
Physical activity reduces the risk of developing cardiovascular diseases (CVD) and dementia. This benefit cannot be explained by changes in traditional CVD risk factors alone, and direct improvements in vascular health are thought to play a key role. However, our understanding of how exercise can be optimized for improvements in blood-vessel health is limited.
High-intensity interval exercise (HIIE) is known to improve peripheral vascular function, and there is a growing interest in the effects of HIIE on cerebrovascular health. However, it is not clear whether the acute improvements in peripheral vascular function following HIIE are also seen in the major blood-vessels of the brain.
In the Bond lab’s study, 30 minutes of HIIE completed at both 75% and 90% V̇O2max improved peripheral vascular function 1 and 3h following exercise in healthy young adults, compared with work-matched continuous moderate-intensity exercise and a sedentary control condition. By contrast, cerebrovascular function was unchanged following all conditions. This is the first study to identify that acute improvements in peripheral vascular function following high-intensity interval exercise are not mirrored by improvements in cerebrovascular function in healthy young adults.
Leveraging Programmable CRISPR-Associated Transposases for Next-Generation Ge...InsideScientific
Dr. Sam Sternberg discusses a novel CRISPR-Cas9 system using programmable, RNA-guided transposase, and highlights its implications for kilobase-scale genome engineering in cell and gene therapies.
The utility of programmable, RNA-guided CRISPR-Cas systems in genome engineering continues to evolve. Nature has afforded scientists novel and diverse gene editing functionality, from nuclease-dependent CRISPR-Cas9 to second-generation base and prime editors that do not produce double-strand breaks.
In this webinar, Dr. Sam Sternberg describes a new CRISPR-Cas9 paradigm relying on nuclease-deficient bacterial transposons that catalyze RNA-guided integration of mobile genetic elements into the genome. The discovery of a fully programmable, RNA-guided transposase lays the foundation for kilobase-scale genome engineering with broad applications for developing cell and gene therapies.
Key Topics Include:
- The basics of first- and second-generation CRISPR-Cas technologies from a scientist at the forefront of their development
- Mechanisms, accommodation, and cell type diversity of CRISPR-Cas programmable transposition
- How transposase factor coordination enables highly specific, genome-wide DNA integration to target sites
- Implications of programmable transposases that obviate the need for DNA double-strand breaks and homologous recombination

- Implementation of key principles into a rodent surgical program
Cardiovascular Autonomic Dysfunction in the Post-COVID Landscape: Detection a...InsideScientific
A world-wide spread of the novel Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has triggered a pandemic and generated over 600 million reported cases around the globe. A substantial portion of patients who suffered Corona Virus Disease 2019 (COVID-19) have not recovered completely but continue to experience lingering symptoms for months to years. This novel clinical syndrome has been termed Long COVID or Post-acute Sequalae of COVID-19 (PASC).
Observational studies have indicated that in about one third of cases PASC can be associated with cardiovascular (CV) autonomic dysfunction including postural orthostatic tachycardia syndrome, inappropriate sinus tachycardia, orthostatic hypotension, reflex syncope and microvascular dysfunction. The presence of CV autonomic dysfunction in PASC is important to detect since although frequently overlooked, it may be effectively treated in contrast to many other Long COVID-related symptoms.
This webinar highlights CV dysautonomia as a specific sequalae of acute COVID-19 and guides the audience in the diagnostic work-up of PASC patients with suspected cardiovascular complications.
Creating Better Gene-Edited Cell Lines with the FAST-HDR SystemInsideScientific
Cell lines are the core of biological research. Scientists need cell lines for drug development, basic biology research, safety testing, and biologic therapeutic production. Since the 1980s, genetic manipulation has allowed researchers to tailor cell lines to the experiment or production purpose. Over time, the requirements for these cell lies have risen. In many cases, the cells require multiple genetic edits and must produce data that passes FDA. Moreover, the current funding environment often requires rapid delivery of these cells so scientists can produce data to support further budget and/or investment. This is particularly acute for knock-in cell lines. Current technologies may take months to complete a cell line, allow a limited number of edits, and often have off-target effects that are not suitable for FDA filings. ExpressCells uses its patented FAST-HDR plasmid--along with CRISPR, to address these problems. The FAST-HDR process can precisely knock-in multiple genes (while supporting other types of genetic modifications), ensure precise placement of these edits, and deliver them months faster than competing technologies.
This webinar will discuss the basis of the FAST-HDR technology and illustrate several uses. The first part is a presentation by Oscar Perez-Leal, MD, the inventor of the technology. Oscar will discuss the problems he faced as a researcher and how FAST-HDR was designed to address them. He will outline the details of the technology, the history of its development, and several examples where he used FAST-HDR. The second part is a conversation with Jon Weidanz, PhD. Jon will outline the challenges he faced at AbeXXa and how he selected a FAST-HDR custom cell line for his project. He'll outline the learnings from using this cell line, some of which were unexpected, but valuable to future development.
By attending this program, attendees will:
- Understand the current challenges in creating custom gene-edited cell lines
- Know the technology underlying the FAST-HDR gene-editing system, including its use with CRISPR
- Be able to describe the advantages of the FAST-HDR system
- Learn about several case studies using gene-edited cell lines
Functional Recovery of the Musculoskeletal System Following Injury - Leveragi...InsideScientific
Watch Dr. Sarah Greising discuss the current pathophysiologic understanding of the skeletal muscle remaining following traumatic musculoskeletal injuries.
Volumetric muscle loss (VML) injuries result in the abrupt loss of skeletal muscle fibers, causing chronic functional disability in part due to limited muscle regeneration and vast co-morbidities. With a focus on clinically relevant outcome measurements for skeletal muscle function in both small and large animal models of VML injury, this webinar presents various near-term interventions for the restoration of tissue function following complex injuries. Interventions evaluated focus on regenerative rehabilitation approaches using regenerative pharmaceuticals to correct underlying muscle pathophysiology.
Designing Causal Inference Studies Using Real-World DataInsideScientific
In this webinar, experts provide an overview of causal inference, along with step-by-step guidance to designing these studies using real-world healthcare data.
Causal inference is used to answer cause and effect research questions and yield estimates of effect. Causal study design considerations and statistical methods address the effects of confounding variables and other potential biases and allow researchers to answer questions such as, “Does treatment A produce better patient outcomes compared to Treatment B?”
Causal study interpretations have traditionally been restricted to randomized controlled trials; however, causal inference applied to observational healthcare data is growing in importance, driven by the need for generalizable and rapidly delivered real-world evidence to inform regulatory, payer, and patient/provider decision making. The application of causal inference methods leads to stronger and more powerful evidence. When these techniques are applied to observational data, the results generated are both from and for the real world.
Presenters walk through several real-world case studies including the PCORI-funded BESTMED study and a collaborative study with a prominent pharmacy payer.
Social Media Data: Opportunities and Insights for Clinical ResearchInsideScientific
Many new data are emerging in recent years - real time data is collected through digital health technologies, including apps and wearables, monitoring data, social media data, public datasets, and patient organization data, in addition to primary and secondary datasets.
Real life data are highly informative and can be used to address a range of challenges throughout the product life cycle. Data from social media can generate valuable insights as patients often gather in digital communities to get answers and share their experiences. Conversations on social networks merit special consideration as they can have real world influence over treatment management decisions.
Social media data can reveal the motivations that impact patient healthcare decisions and behaviors through each stage of the care pathway. These data provide both the patient and caregiver perspectives at the same time. For this reason, conversations on social networks offer an opportunity to deepen our understanding on:
- The fears and hopes associated with patient treatments
- Daily needs and difficulties patients are facing in managing their disease
- The impact of disease on patient health related quality of life
- Identification in real life of the stages of the care pathway and patient perceptions
- Reactions to health policies
Watch this webinar for insights on how to collect, use, analyze, and interpret social media data in different contexts. Our experts share knowledge from over fifteen years of successfully developing and adapting algorithms to treat this kind of data.
We Are More Than What We Eat Dietary Interventions Depend on Sex and Genetic ...InsideScientific
To learn more visit: https://insidescientific.com/webinar/we-are-more-than-what-we-eat-dietary-interventions-depend-on-sex-and-genetic-background/
Despite evidence that sex and genetic background are key factors in the response to diet, most studies of how diet regulates metabolic health and even longevity in mice examine only a single strain and sex.
Using multiple strains and both male and female mice, Dr Lamming's team has found that improvements in metabolic health and in longevity in response to reduced levels of protein or specific amino acids strongly depend on sex and strain. While some phenotypes were conserved across strains and sexes, including increased glucose tolerance and energy expenditure, they observed high variability in adiposity, insulin sensitivity, and circulating hormones. Using a multi-omics approach, they identified mega-clusters of differentially expressed hepatic genes, metabolites, and lipids associated with each phenotype, gaining new insight into role of the energy balance hormone FG21 in the response to protein restriction.
Antibody Discovery by Single B Cell Screening on Beacon®InsideScientific
Amy Sheng, PhD provides an overview of antibody screening platforms and presents applications and case studies using the Beacon® platform for antibody discovery.
Single B cell screening is a powerful and efficient strategy for generating antigen-specific monoclonal antibodies. Distinguished with fluorescence-activated B cell sorting, the Beacon® platform is based on plasma cell screening, making it easier to obtain antibody genes.
The Beacon® single-cell optofluidic system combines a unique optoelectro positioning (OEP) technology with novel microfluidic technology. It can be used to accurately select single cells on a chip, perform multiple single-cell assays, and export target cells based on specific results. The Beacon® optofluidic platform preserves the diversity of B cells, generating high-quality positive hits at an early stage of discovery and avoiding the loss of “good clones”.

Strategic Approaches to Age-Related Metabolic Insufficiency and Transition in...InsideScientific
In this webinar, Dr. Dennis Turner delves into dementia syndrome, the metabolic changes that occur, and the importance of proper physiological monitoring of animal models.
Brain metabolism transforms with normal aging, and transient, dynamic metabolic insufficiency may underlie critical progression from aging into dementia syndrome and Alzheimer’s disease (AD). Age-related brain metabolism balances vascular-related substrate supply and transport mechanisms into extracellular space to neurons with cellular metabolic needs and utilization. Dynamic metabolic insufficiency can occur when there is intermittent supply-demand mismatch.
Adequacy of neurovascular coupling to provide sufficient cerebral blood flow (CBF) to meet neuronal demand in vivo in a mouse AD model, compared to aged controls were studied. Dr. Turner’s lab analyzed the response to maximal neuronal metabolic demands, spreading depression and anoxia, using imaging, CBF measurements, and oxygen and glucose levels. These in vivo studies require human-similar anesthesia conditions, through monitoring temperature, blood pressure/pulse oximetry, and respiration, to maintain homeostasis. The lab confirmed abnormal neurovascular coupling in a mouse model of AD in response to these metabolic challenges, showing disruption much earlier in dementia than in equivalently aged individuals. Chronic metabolic treatments could influence dementia syndrome progression.
The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptxMAGOTI ERNEST
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).
This presentation explores a brief idea about the structural and functional attributes of nucleotides, the structure and function of genetic materials along with the impact of UV rays and pH upon them.
ANAMOLOUS SECONDARY GROWTH IN DICOT ROOTS.pptxRASHMI M G
Abnormal or anomalous secondary growth in plants. It defines secondary growth as an increase in plant girth due to vascular cambium or cork cambium. Anomalous secondary growth does not follow the normal pattern of a single vascular cambium producing xylem internally and phloem externally.
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

16. Transcelerate Biopharma’s experiment - Analysis
Ø MD for each subject & studywide was calculated separately for vital signs and spirometry measurements.
Ø A large MD for a subject would correspond to an outlier, and a small MD would correspond to an inlier.
Ø Carryover effect/repeated values
Ø Carryover, defined as an exact match of a value for a subject from one visit to the next, was calculated.
Ø Repeated values, defined as the number of identical values for a subject within a visit (for spirometry) or overall,
were calculated.
Ø Digit preference and rounding
Ø For each subject, last digit frequency distribution was compared to other subjects at that site and across the study
using either a Chi-square or Fisher exact test, as appropriate, and by comparing the mean and SD of last digit value
within a subject to studywide distributions using the CIs.
16
17. Transcelerate Biopharma’s experiment - Results
Ø Results
Ø The algorithm identified 11 sites (19%), 19 sites (31%), 28 sites (16%), and 45 sites (25%) as having potentially
fabricated data for studies 2A, 2, 1A, and 1, respectively.
Ø For study 2A, 3 of 7 sites with fabricated data were detected, 5 of 7 were detected for studies 2 and 1A, and 6 of 7
for study 1.
Ø Except for study 2A, the algorithm had good sensitivity and specificity (>70%) for identifying sites with fabricated
data.
Ø Conclusions
Ø Recommendation of a cross-functional, collaborative approach to statistical monitoring that can adapt to study
design and data source and use a combination of statistical screening techniques and confirmatory graphics.
17
18. Limitation and Future Trend
Limitation
Ø The effectiveness of statistical monitoring is questionable in low–data volume conditions
Ø A site may not be flagged if it is small (small sample size)
Ø A small site may be flagged because of a single subject, increasing false-positive rates
Ø An adaptive algorithm that uses different cut-offs for subject and site flagging depending on the stage and size of the
study may be required
The success of Central monitoring activities relies on the skills of people, well-defined processes, and technologies that
enable the translation of data into information, and resulting actions and decisions.
Future Trend
Ø Increased use of AI and ML for pattern/anomaly identification, review using data visualization and automated statistical
analyses

Data Integrity Detection
Using Artificial Intelligence

42. Machine Learning Methodology
ØMachine Learning (ML) techniques are
used to assess the integrity/acceptability
of ECG signals from wearable devices.
ØML algorithms were trained and tested on
the Physionet/Cinc 2017 challenge
training dataset.
ØThis Dataset is a good representation of
the data obtained from a wearable device.
42
43. Performance of Algorithms
• The study tested 13
machine learning
algorithms
• This presentation will
focus on the top three
performing algorithms
that predict ECG signal
integrity
43
44. Bagging Using Neural Networks-Simulation
ØBootstrap Aggregation/Bagging (B)-Ensemble
method where neural network models are
generated by sampling with replacement at
random.
ØThis random sampling process found three 3 NN
models that exhibited excellent results.
ØThe figure shows the model (neural network) that
exhibited the best performance in predicting ECG
signal with a 99.47% accuracy. 44
45. Gradient Boosting Algorithm-Processing
ØEnsemble technique in which a sequence of
variables is constructed additively to find the
best prediction.
ØAt each iteration a variable is added and accuracy
is checked by noting how many ECG raw values it
failed to predict.
ØThe iteration that minimizes false predictions
(circles and squares) is then adopted for Decision
Trees (next slide). 45
46. Gradient Boosting using Decision Trees
ØA decision tree (DT) is a learning method in
which important features are selected from
regression models.
ØPredicted values are assigned T(1)/F(0) (Figure
6) if it matches the raw data. The DT ensemble
method predicted ECG signal at 98.92% and
95.25% accuracy
ØDT requires minimal computing memory and
can classify ECG signals with lightning speed. 46
47. Evaluating Costs through Computation Complexity
ØThe bagging and gradient boosting models
both require 99 multiplication and 90-91
addition computations.
ØThe total energy required to execute the
computations is lowest (0.039)-both Bagging
and Gradient Boosting can be implemented
on wearable technology at a low cost.
47
48. Conclusion
ØThe neural network ensemble using
bagging and gradient boosting (encircled as
B2 and GB2 box plots in the figure) exhibit
the best integrity classification across all
parameters.
ØComputer chips with Energy-efficient deep
neural networks have the potential to be
deployed on IoT wearable devices for
reliable ECG signal quality. 48
