Linkage Detection of Features that Cause Stroke using Feyn Qlattice Machine L...PurwonoPurwono4
Stroke is a disease caused by brain tissue damage because of blockage in the
cerebrovascular system that disrupts body sensory and motoric systems
Stroke disease is one of the highest death cause in the world. Data collection
from Electronic Health Records (EHR) is increasing and has been included
in the health service big data. It can be processed and analyzed using machine
learning to determine the risk group of stroke disease. Machine learning can
be used as a predictor of stroke causes, while the predictor clarifies the
influence of each cause factor of the disease. Our contribution in this research
is to evaluate Feyn Qlattice machine learning models to detect the influence
of stroke disease's main cause features. We attempt to obtain a correlation
between features of the stroke disease, especially on the gender as a feature,
whether any other features can influence the gender feature. This research

present the design of an expert system that aims to provide the patient with background for suitable
diagnosis and treatment (Especially Angina Pectoris and Myocardial infarction). The proposed
methodology is composed of four stages. The first stage is receiving the symptoms from the patient. The
second stage is requesting from the patient to make some analysis and investigation to help the system to
make a correct decision in the diagnosis. The third stage is doing diagnosis of patient according to
information from patient (symptoms, analysis and investigation). The four stage is determining the name of
appropriate medication or what should be done until the patient recovers (step therapy), so this system is
able to give appropriate diagnosis and treatment for two heart diseases namely; angina pectoris and
infarction. There are several programs used for diagnosis and system analysis, such as CLIPS and
PROLOG. A medical expert system in this search made by Visual Prolog 7.3 is proposed.
A disorder or illness called heart failure results in the heart becoming weak or
damaged. In order to avoid heart failure early on, it is crucial to understand the
causes of heart failure. Based on validation, two experimental processing steps
will be applied to the dataset of clinical records related to heart failure. Testing
will be done in the first step utilizing six different classification algorithms,
including K-nearest neighbor, neural network, random forest, decision tree,
Naïve Bayes, and support vector machine (SVM). Cross-validation was
employed to conduct the test. According to the results, the random forest
algorithm performed better than the other five algorithms in tests employing
the algorithm. Subsequent testing uses an algorithm with the best accuracy
value, which will then be tested again using split validation with varying split
ratios and genetic algorithms as a selection feature. The value generated from
testing using the genetic algorithm selection feature is better than the random
forest algorithm alone, which is recorded to produce an accuracy value of
93.36% in predicting the survival of heart failure patients.

In this paper, three machine learning (ML) techniques −Classification and Regression tree (CART), Neural Networks (NN), and Support vector machine (SVM)− are utilized to find the best attributes for estimating the severity of heart failure. The data is collected from three different resources, then each input attribute used for assessing the severity of heart failure is analyzed individually after implementing the machine learning techniques. Finally, the most important supportive attributes are presented in this paper by which medical staffs can identify heart failure severity fast and more accurately. In fact, by screening important attributes, clinicians can make better decision about right treatment procedures or preventive actions that reduce risk of heart attacks.
Detection of heart pathology using deep learning methodsIJECEIAES
In the directions of modern medicine, a new area of processing and analysis of visual data is actively developing - a radio municipality - a computer technology that allows you to deeply analyze medical images, such as computed tomography (CT), magnetic resonance imaging (MRI), chest radiography (CXR), electrocardiography and electrocardiography. This approach allows us to extract quantitative texture signs from signals and distinguish informative features to describe the heart's pathology, providing a personified approach to diagnosis and treatment. Cardiovascular diseases (SVD) are one of the main causes of death in the world, and early detection is crucial for timely intervention and improvement of results. This experiment aims to increase the accuracy of deep learning algorithms to determine cardiovascular diseases. To achieve the goal, the methods of deep learning were considered used to analyze cardiograms. To solve the tasks set in the work, 50 patients were used who are classified by three indicators,
13 anomalous, 24 nonbeat, and 1 healthy parameter, which is taken from the MIT-BIH Arrhythmia database.
Chronic disease (CD) such as kidney disease and causes severe challenging issues to the people all around the world. Chronic kidney disease (CKD) and diabetes mellitus (DM) are considered in this paper. Predicting the diseases in earlier stage, gives better preventive measures to the people. Healthcare domain leads to tremendous cost savings and improved health status of the society. The main objective of this paper is to develop an algorithm to predict CKD occurrence using machine learning (ML) technique. The commonly used classification algorithms namely logistic regression (LR), random forest (RF), conditional random forest (CRF), and recurrent neural networks (RNN) are considered to predict the disease at an earlier stage. The proposed algorithm in this paper uses medical code data to predict disease at an earlier stage.
ENHANCING ACCURACY IN HEART DISEASE PREDICTION: A HYBRID APPROACHindexPub
Predicting the onset of heart disease accurately is essential for early diagnosis and prevention of this global pandemic. The paper suggests a hybrid method to improve heart disease prediction. The research examines several machine learning (ML) models for detecting heart illness and assesses how well they predict heart disease. To enhance precision, the hybrid method employs not one but many machine learning methods. The hybrid method employs SVMs, random forests, and neural networks as its machine- learning algorithms. When it comes to classification, SVM is a very effective method. The data points are separated into classes, and the optimal hyperplane to do this is the goal. SVM can learn the boundaries and patterns between various risk variables and efficiently categorize people as having heart disease or not. Random forests are a kind of ensemble learning that uses several individual decision trees to make a final determination. The characteristics used to construct each decision tree are chosen at random. Each decision tree contributes to the overall forecast, which is then aggregated. Due to their versatility, random forests may be used to the prediction of cardiovascular disease. Neural networks are a kind of algorithm that takes their cues from the way the human brain operates. They are made up of several layers of artificial neurons working together to learn intricate patterns from data. Medical diagnosis is only one field where neural networks have been shown to be useful. In the hybrid method, neural networks may learn complex associations between risk factors and cardiovascular disease and provide reliable prognoses based on this information. The hybrid method enhances the accuracy of heart disease prediction by combining the benefits of various machine-learning techniques
Detection of myocardial infarction on recent dataset using machine learningIJICTJOURNAL
In developing countries such as India, with a large aging population and limited access to medical facilities, remote and timely diagnosis of myocardial infarction (MI) has the potential to save the life of many. An electrocardiogram is the primary clinical tool utilized in the onset or detection of a previous MI incident. Artificial intelligence has made a great impact on every area of research as well as in medical diagnosis. In medical diagnosis, the hypothesis might be doctors' experience which would be used as input to predict a disease that saves the life of mankind. It is been observed that a properly cleaned and pruned dataset provides far better accuracy than an unclean one with missing values. Selection of suitable techniques for data cleaning alongside proper classification algorithms will cause the event of prediction systems that give enhanced accuracy. In this proposal detection of myocardial infarction using new parameters is proposed with increased accuracy and efficiency of the existing model. Additional parameters are used to predict MI with more accuracy. The proposed model is used to predict an early diagnosis of MI with the help of expertise experiences and data gathered from hospitals.
An internet of things-based automatic brain tumor detection systemIJEECSIAES
Due to the advances in information and communication technologies, the usage of the internet of things (IoT) has reached an evolutionary process in the development of the modern health care environment. In the recent human health care analysis system, the amount of brain tumor patients has increased severely and placed in the 10th position of the leading cause of death. Previous state-of-the-art techniques based on magnetic resonance imaging (MRI) faces challenges in brain tumor detection as it requires accurate image segmentation. A wide variety of algorithms were developed earlier to classify MRI images which are computationally very complex and expensive. In this paper, a cost-effective stochastic method for the automatic detection of brain tumors using the IoT is proposed. The proposed system uses the physical activities of the brain to detect brain tumors. To track the daily brain activities, a portable wrist band named Mi Band 2, temperature, and blood pressure monitoring sensors embedded with Arduino-Uno are used and the system achieved an accuracy of 99.3%. Experimental results show the effectiveness of the designed method in detecting brain tumors automatically and produce better accuracy in comparison to previous approaches.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Erwin Panggabean (Comparative Analysis Of Dempster Shafer Method With Certainty Factor Method For Diagnose
Stroke Diseases)
diagnosis of stroke are: Lack of information
about the types and symptoms and stroke, so
people do not know to take appropriate
action to deal with stroke [9]. Limitations of
a good expert in situations that can not reach
all places and memory and stamina are
reduced due to age, which in diagnosing
could have made a mistake so as to continue
to the results of the solution taken [10].
II. Methods
The authors conducted a study at
Bhayangkara Hospital Medan which is
located on Jalan KH. Wahid Hasyim No.01,
Merdeka, Medan, Medan City. The author
conducted an interview with a specialist
neurologist dr. Meity, M.B., SpS. In this
hospital there is only one neurologist who
still diagnose stroke patients in the patient
manually, in the sense of stroke diagnosis
results rely heavily on examination and
decision of the expert. While the schedule of
practice of neurologist at Bhayangkara
Hospital is on Monday, Wednesday and
Thursday of the week. So the patient must
wait for the day in accordance with the
doctor's schedule at the hospital to get the
services of a specialist neurologist in poly
nerve Hospital Bhayangkara[11].
Here the author will explain about the use of
two methods used to draw conclusions from
the table type of disease and symptoms.
There are four types of diseases directed by
K01, K02, ... KO4 and 30 symptoms
addressed by G01, G02, ..., G030. Of the 30
symptoms compiled and 4 types of diseases
are arranged as conclusions. This symptom is
a knowledge base to make a conclusion into a
goal. The following is a table of types of
illnesses and symptoms[12].
III. Result
Where the bell value (believe) is the value of
weight inputted by the expert [13]. Sample
case study:
A father has the following symptoms: G03
(Difficulty speaking); G04 (Paralysis and
sensory deficit on right arm and leg); G011
(high blood pressure); G016 (Can not move
limbs at all). The first characteristic is blurred
vision, which is characteristic of a brief brain
attack (K01), brain tissue death (K02), and
spontaneous subarkhnoid haemorrhage (K03)
[14].
m_1 {K01, K02, K03} = 0.4
m_1 {Ө} = 1 - 0.4 = 0.6
The second characteristic is the paralysis and
sensory deficits of the right arm and leg that
are characteristic of the classification of
Death of Brain Network or K02 [15].
m_2 {K02} = 0.6
m_2 {Ө} = 1 - 0.6 = 0.4
The formula for calculating the new density
using the formula [3]:
To facilitate the calculation of the sub-
assemblies brought into shape Table. The
first column contains all the sets on the first
characteristic with m_1 as the density
function. The first row contains all subsets
of the second symptom with m_ (2) as a
density function.
Table 1 Density Function m_1 and m_ (2)
{K01,K02,K03} = =
0,4
{K02} = = 0,36
{Ө} = = 0,24
The third characteristic is high blood
pressure, which is characteristic of the
Classification of Brain Attack (K01), Death

Erwin Panggabean (Comparative Analysis Of Dempster Shafer Method With Certainty Factor Method For
Diagnose Stroke Diseases)
of Brain Network (K02), Spontaneous
Subarkhnoid Bleeding (K03), Intra-Cellular
Bleeding (K04).
{K01,K02,K03,K04} = 0,6
{Ө} = 1 – 0,6 = 0,4
Then we have to recalculate the new
density values for each subset with the m_5
density function. As in the previous step, we
compile the table with the first column
containing the result set of combinations of
characteristics 1, characteristic 2, and
characteristic 3, with the density function
m_3. Whereas the first line contains subsets
on characteristics 1, characteristic 2,
characteristic 3, and characteristic 4 with the
density function m_4.
Table 2 Density Function m_3 and m_ (4)
Next is calculated the new density for
combination (m_5):
{K01,K02,K03} = =
0,4424778761
{K02} = =
0,3982300885
{K01,K02,K03,K04} = =
0,1592920354
{Ө} = = 0,1061946903
The fourth characteristic is that it can not
move the limbs at all which is characteristic
of the classification of Brain Death Network
(K02).
m_6 {K02} = 0.8
m_6 {Ө} = 1 - 0.8 = 0.2
Table 3 Density Function m_5 and m_6
Here the author will again lift the example
of the same case study that is a father who
has symptoms of the disease as follows: G03
(Difficulty speaking); G04 (Paralysis and
sensory deficit on the right arm and limb);
G011 (high blood pressure); G016 (Can not
move arms and legs at all).
CF [h, e] = MB [h, e] - MD [h, e]
To calculate the value of Dempster Shafer
stroke is selected using the Measure of Belief
(MB) and Measure of Disbelief (MD) values
that have been determined on each symptom.
Table 4 Measure Table
To find the value of CF can be obtained
from:
MB value = 0.9808 - MD value =
0.21960448 = 0.76119552.Diagnosis Result:
You are indicated by Death of Brain Disease
(Thick Infarction)
CF value: 0.76119552

Vol. 2, No. 1, June 2018, pp.32-37
Erwin Panggabean (Comparative Analysis Of Dempster Shafer Method With Certainty Factor Method For Diagnose
Stroke Diseases)
Improvement of infant neonate infarction
condition if lag time between attack and
handling still less than three hours and
immediately opening the blockage, then can
still be expected optimal recovery in patient.
In addition to this, efforts to reduce risk
factors for the occurrence of infarct among
other things, by maintaining the stability of
blood pressure, maintaining the balance of
weight badaa, as well as the stability of blood
sugar and cholesterol levels by improving
diet and not smoking.
IV. Conclusion
Based on the results of analysis of stroke
diagnosis result between Dempster Shafer
method with Certainty Factor method, it can
be concluded:
1. Dempster Shafer's method of diagnosing
stroke in Medan City is better than
Certainty Factor method. Level of
accuracy of expert system diagnosis with
Certainty Factor method is 80%, while
expert system diagnosis result with
Dempster Shafer method is 85%.
2. The amount of Certainty Factor (CF) value
generated from the Certainty Factor
method and the density value generated
from the Dempster Shafer method and the
diagnosis result of each method
determined by the number of matches
between the input symptoms and the
belief value of each symptom.
3. The magnitude of the Certainty Factor
(CF) value resulting from the Certainty
Factor method of each possible illness is
always between 0 and 1, with the highest
Certainty Factor value being the strongest
possible diagnosis of the disease.
