A bstract The COVID-19 disease has widely spread all over the world since beginning of 2020. On January 30, 2020 World Health Organization (WHO) declared a global health emergency. At time writing this paper number infected about 2 million people worldwide and took 125,000 lives, advanced public systems European countries as well USA were overwhelmed. In paper, we propose an eXplainable Deep Learning approach to detect from computer tomography (CT) - Scan images. rapid detection any case is...
As COVID-19 hounds the world, common cause of finding a swift solution to manage pandemic has brought together researchers, institutions, governments, and society at large. The Internet Things (IoT), artificial intelligence (AI)-including machine learning (ML) Big Data analytics-as well as Robotics Blockchain, are four decisive areas technological innovation that have been ingenuity harnessed fight this future ones. While these highly interrelated smart connected health technologies cannot...
A computer vision approach to classify garbage into recycling categories could be an efficient way process waste. This project aims take waste images and them four classes: glass, paper, metal and, plastic. We use a image database that contains around 400 for each class. The models used in the experiments are Pre-trained VGG-16 (VGG16), AlexNet, Support Vector Machine (SVM), K-Nearest Neighbor (KNN) Random Forest (RF). Experiments showed our reached accuracy 93%.
Traditionally, in supervised machine learning, (a significant) part of the available data (usually 50%-80%) is used for training and rest—for validation. In many problems, however, are highly imbalanced regard to different classes or does not have good coverage feasible space which, turn, creates problems validation usage phase. this paper, we propose a technique synthesizing likely help balance as well boost performance terms confusion matrix overall. The idea, nutshell, synthesize samples...
This article describes a novel approach to the problem of developing explainable machine learning models.

The constitutes mapping from continuous multidimensional state space characterizing vehicle positions and velocities discrete set actions in longitudinal lateral direction. It is obtained by applying customized version double Q-network algorithm [2]. main idea approximate DRL...
Abstract The infection by SARS-CoV-2 which causes the COVID-19 disease has spread widely over whole world since beginning of 2020. Following epidemic started in Wuhan, China on January 30, 2020 World Health Organization (WHO) declared a global health emergency and pandemic. In this paper, we describe publicly available multiclass CT scan dataset for identification. Which currently contains 4173 CT-scans 210 different patients, out 2168 correspond to 80 patients infected with confirmed...
The cold brew method consists of soaking roasted and ground coffee beans either in or ambient water (4–23 °C) for up to 24 h. Using this technique, a drink with unique sensory profile is obtained. This study was conducted determine the shelf life organic (pH~5.0) made from subjected three roast levels: light, medium dark. pasteurized at 90 °C/30 s, ultra-clean filled into high-density polyethylene bottles, stored 4 °C Physicochemical, enzymic tests, instrumental color analysis,...
Abstract Recent advancements in large foundation models have revealed impressive capabilities mastering complex chemical language representations. These undergo a task-agnostic learning phase, characterized by pre-training on extensive unlabeled corpora followed fine-tuning specific downstream tasks. This methodology reduces reliance labeled data, facilitating data acquisition and broadening the scope of representation. However, real-world scenarios often pose challenges due to domain shift,...
Recidivism prediction provides decision makers with an assessment of the likelihood that a criminal defendant will reoffend can be used in pre-trial decision-making. It also for locations where crimes most occur, profiles are more likely to commit violent crimes. While such instruments gaining increasing popularity, their use is controversial as they may present potential discriminatory bias risk assessment. In this paper we propose new fair-by-design approach predict recidivism....
Abstract The Covid-19 disease has spread widely over the whole world since beginning of 2020. Following epidemic which started in Wuhan, China on January 30, 2020 World Health Organization (WHO) declared a global health emergency and pandemic. Researchers different disciplines work along with public officials to understand SARS-CoV-2 pathogenesis jointly policymakers urgently develop strategies control this new disease.
