Exploratory Sequential Data Analysis (ESDA) is used to analyze sequential data to identify patterns over time in order to help understand systems, environments, and behaviors. ESDA analyzes preserved sequential data in an exploratory manner guided by methodological traditions to seek meaning related to a research or design question. It is used to observe what people do over time and includes both quantitative techniques like statistical analysis and qualitative techniques like interaction analysis. An example of ESDA output is a timeline that shows the lag sequential analysis of events.

The Semantic Web vision emerged with a promise to collect and interlink semantically relevant data from diverse sources in order to to achieve a full potential of the Web. After more than a decade of diligent research, it is the time to start summing up what has been accomplished and how mature Semantic Web research is, so that plans for the future can be charted. One of the key trails of a mature discipline is to have well-designed research methods allowing researchers to establish evidence about the effectiveness of the research ideas. It is equally important to to have knowledge translation methods that allow for transferring the established evidence to decision makers in practice. In this talk, we will first share some experience and challenges in conducting experiments in the area of the Semantic Web. We will next discuss findings of systematic reviews conducted to estimate the level of quality of the existing research results based on the criteria well-known in medical research and recently adopted in empirical software engineering. We will conclude the talk by discussing the importance and potential milestones for the Semantic Web in order to become an evidence-based discipline (similar to medicine or education) capable of producing strong research evidence transferable to practice.

Survival analysis is an important method for analysis time to event data for biomedical and reliability applications. It is often done with semiparametric methods e.g. the Cox proportional hazards model. In this presentation I discuss an alternative parametric approach to survival analysis that can overcome some of the limitations of the Cox model and provide additional flexibility to the modeler. This approach may also be justified from a Bayesian perspective and the connection is shown as well. Simulations and case studies that illustrate the flexibility of the GAM approach for survival analysis and its equivalent performance to existing methods for survival data are discussed in the text. The material presented herein are based on two publications: 1) Argyropoulos C, Unruh ML. Analysis of time to event outcomes in randomized controlled trials by generalized additive models. PLoS One. 2015 Apr 23;10(4):e0123784. doi: 10.1371/journal.pone.0123784. PMID: 25906075; PMCID: PMC4408032. 2)Bologa CG, Pankratz VS, Unruh ML, Roumelioti ME, Shah V, Shaffi SK, Arzhan S, Cook J, Argyropoulos C. High performance implementation of the hierarchical likelihood for generalized linear mixed models: an application to estimate the potassium reference range in massive electronic health records datasets. BMC Med Res Methodol. 2021 Jul 24;21(1):151. doi: 10.1186/s12874-021-01318-6. PMID: 34303362; PMCID: PMC8310602.

Term frequencies and inverse document frequencies have been successfully applied in determining weighting for document rankings. However these have been more successful in text mining and in extraction techniques used in the web. Concept mining has become increasingly popular in the research and application areas of Computer Science. This paper attempts to demonstrate the limited usage of term frequency and inverse document frequency for the application of weighting calculations for ranking documents that are based on concept quantifications. The case study considered for experiment in this paper, is based on concept terms of David Merrill’s First Principles of Instruction (FPI). Merrill’s FPI applies cognitive structures explicitly for analyzing instructional materials. Therefore it is justified that the terms categorized under each cognitive structure (or portrayal) of FPI can be taken as respective concept of that portrayal. As question papers are representative of cognitive structures in a more clear and logical way, four question papers on ‘C Language’ have been considered for the experimental study, that are detailed in this paper. Manual method has been adopted for the computation of quantities of portrayals in selected documents for the purpose of comparative study. As manual method is accurate, the values (results) are considered as benchmark values. These benchmark values are considered for comparing with normalized term frequencies that are derived (experimented) from automated extractions from the same selected documents. The study is however limited to four documents only. Conclusions are drawn from this experimental study, which will be of immense use to concept mining researchers as well as for instructional designers.

I'm excited to share my latest predictions on how AI, robotics, and other technological advancements will reshape industries in the coming years. The slides explore the exponential growth of computational power, the future of AI and robotics, and their profound impact on various sectors. Why this matters: The success of new products and investments hinges on precise timing and foresight into emerging categories. This deck equips founders, VCs, and industry leaders with insights to align future products with upcoming tech developments. These insights enhance the ability to forecast industry trends, improve market timing, and predict competitor actions. Highlights: ▪ Exponential Growth in Compute: How $1000 will soon buy the computational power of a human brain ▪ Scaling of AI Models: The journey towards beyond human-scale models and intelligent edge computing ▪ Transformative Technologies: From advanced robotics and brain interfaces to automated healthcare and beyond ▪ Future of Work: How automation will redefine jobs and economic structures by 2040 With so many predictions presented here, some will inevitably be wrong or mistimed, especially with potential external disruptions. For instance, a conflict in Taiwan could severely impact global semiconductor production, affecting compute costs and related advancements. Nonetheless, these slides are intended to guide intuition on future technological trends.

ScyllaDB has the potential to deliver impressive performance and scalability. The better you understand how it works, the more you can squeeze out of it. But before you squeeze, make sure you know what to monitor! Watch our experienced Postgres developer work through monitoring and performance strategies that help him understand what mistakes he’s made moving to NoSQL. And learn with him as our database performance expert offers friendly guidance on how to use monitoring and performance tuning to get his sample Rust application on the right track. This webinar focuses on using monitoring and performance tuning to discover and correct mistakes that commonly occur when developers move from SQL to NoSQL. For example: - Common issues getting up and running with the monitoring stack - Using the CQL optimizations dashboard - Common issues causing high latency in a node - Common issues causing replica imbalance - What a healthy system looks like in terms of memory - Key metrics to keep an eye on This isn’t “Death-by-Powerpoint.” We’ll walk through problems encountered while migrating a real application from Postgres to ScyllaDB – and try to fix them live as well.
