The separation or suppression of background noise in a given recording to extract clear speech benefits humans with hearing aids and devices such as Automatic Speech Recognition systems. In recent years, various experiments have been conducted to develop a Speech Enhancement (SE) model or framework that would produce high-quality estimations based on classical algorithms or Deep Neural Network techniques. This work investigates the most promising SE approaches, by replicating the experiments and using accurate training and testing criteria and the same set of evaluation metrics, to determine what produces better estimates of the clean speech signal.

Early detection of COVID-19 is of vital importance. The group of scientists’ study is aimed to automatically detect COVID-19 disease from CXR (chest radiography imaging) images while maximizing the accuracy in detection. Their proposed framework involves image enhancement technique using dataset which consists of three classes: COVID-19, viral pneumonia and normal CXR imagery. To establish the robustness of the proposed model, stratified 5-fold cross-validation is carried out. The results suggest that image enhancement, segmentation and future fusion methods used in this study could indeed improve classification results.

"In this research, a study of cross-linguistic speech emotion recognition is performed. For this purpose, emotional data of different languages (English, Lithuanian, German, Spanish, Serbian, and Polish) are collected, resulting in a cross-linguistic speech emotion dataset with the size of more than 10.000 emotional utterances. Despite the bi-modal character of the databases gathered, our focus is on the acoustic representation only. The assumption is that the speech audio signal carries sufficient emotional information to detect and retrieve it. Several two-dimensional acoustic feature spaces, such as cochleagrams, spectrograms, mel-cepstrograms, and fractal dimension-based space, are employed as the representations of speech emotional features. A convolutional neural network (CNN) is used as a classifier. The results show the superiority of cochleagrams over other feature spaces utilized. In the CNN-based speaker-independent cross-linguistic speech emotion recognition (SER) experiment, the accuracy of over 90% is achieved, which is close to the monolingual case of SER. Read article "

Feedback and thanks from doctoral students
"At the Institute of Data Science and Digital Technologies, VU MIF's HPC service infrastructure was used for doctoral studies. The goal of my dissertation research is to investigate deep recurrent neural networks for monitoring the state of sea traffic - predicting the ship's progress. VU MIF's supercomputer resources with GPU calculations were used to create artificial intelligence-based models that solve the regression task. The models created from historical big AIS (Automatic Identification System) data are able to predict the ship's trajectory into the future and this allows to assess the collision risks of ship traffic and detect anomalies at sea. As artificial neural networks are not deterministic, the experiments were repeated several times to ensure the robustness of the results, which was well achieved with the available MIF HPC resources, which can be easily accessed and computed. A great recognition of all this work is the publication of a scientific paper in a highly-ranked EAAI journal, in which the results of the study are presented."
“We used the VU MIF supercomputer for large-scale computations to model chemical processes in electrochemical microscopy. The results have been published in high-level application journals. "
“MIF supercomputer resources are useful in interdisciplinary research with scientists at the VU GMC Institute of Biochemistry. The subject of these investigations is the electrochemical properties of damaged (defective) phospholipid membranes. The supercomputer analyzes a large number of three-dimensional models of these membranes using the finite element method (FEM). This simulation avoids the complexity of working with real membranes in the laboratory and allows you to obtain the required information on the properties of the membranes being studied more quickly."
“At VU MIF Supercomputer, we are conducting research on algorithms for electroencephalogram (EEG) analysis. A supercomputer is especially useful for such research because we can test many algorithm configurations at a time and further explore the best one. Other algorithms we can parallelize, then we get acceleration on the supercomputer. We are currently investigating algorithms for EEG peak search and classification based on diagnosis, and apply the results to writing a doctoral dissertation, preparing scientific publications, and giving presentations at international and national scientific conferences. ”

The graduate, who has successfully completed the VU MIF bachelor's study program "Econometrics" and defended her bachelor's thesis on the topic "Assessing the popularity of youtube videos using publicly available metadata", thanks the Information Technology Open Access Research Center for resources. This paper analyses the video metadata and derived parameters collected by the YouTube Data Application Programming Interface. After assessing significant differences in means among popularity groups by using statistical tests, data clustering algorithms: k-means and self-organising neural networks were applied, to search for trends in the formation of popularity groups. Classification of video popularity was also performed using three machine learning methods: support vector machine, random forest and multinomial logistic regression classifiers. A comparative analysis of the algorithms was carried out and the feature sets that most accurately classify the popularity level were selected. The aim of the final work was to contribute to the development of exception identification algorithms that are able to efficiently process traffic data.

Business and other reviews
The company ZIVE has developed an electrocardiogram device that can be worn on a person's chest and used at home during sports or any other daily activities. Heart activity can be monitored 24x7. When connected to a smartphone or tablet, the app displays detailed heart activity data in real time. After analyzing the data with an AI model, early diagnosis of heart disease can be made, thus providing added value to the user. With the help of MIF scientists and usage of VU MIF HPC resources the AI algorithm was extended with new parameters and their impact on the results was investigated. The developed AI solution is being deployed in medical technology, in collaboration between business and science, using the latest high-performance computing techniques to bring early cardiac diagnostics to the user.
