Arsen Matej Golubovikj is a second-year student of Data Science at UP FAMNIT. He completed his Bachelor's degree in Computer Science at UP Famnit in September 2020, and is now working towards his Master's degree. He will be presenting the topic of his Master's thesis that he is completing under the mentorship of assist. prof. Branko Kavšek and prof. Marko Tkalčič.

NASLOV: Imputing Missing Answers In The World Values Survey
---------------------------------------------------------------------------------------

POVZETEK:

Many areas of science, in particular social sciences, use questionnaires to gather data. The process of collecting data through a questionnaire, called a survey, is often the prime means of gathering data directly from participants, however, it's prone to missing data. In order to keep the full survey sample, researchers must often use imputation to deal with this problem. Methods for imputation can sometimes offer reasonable estimates for the missing data, however, in the case of the survey: (i) imputation can add high noise to the data, which influences the inference, (ii) imputation becomes unreliable when more than 40% of the data is missing.
This thesis attempts to address these issues by evaluating if the usage of methods stemming from collaborative filtering (CF) in recommender systems can yield more accurate imputations of missing values in survey data. The rationale for the usage of these methods is (i) the similarity between the problem framing, methods and data representation used in CF and questionnaire imputation; (ii) the effectiveness of CF-based methods in recommender systems, especially in cases where much of the data is unavailable.
We use data from the World Values Survey, a valuable dataset in social science of high volume and veracity, to compare (i) one simple approach to imputation, (ii) two established imputation approaches (iii) two matrix completion techniques stemming from collaborative filtering.The results show that our chosen matrix completion techniques stemming from collaborative filtering perform comparable, but not better than existing imputation techniques in the case of the survey. The right technique for imputation often depends on the problem, these results beckon the consideration of CF-based techniques in future research on survey imputation.

Seminar bo tokrat izjemoma v torek od 14 uri in bo potekal v angleškem jeziku v Zoom "klepetalnici" na naslovu:

NASLOV: Neural Network Based Classification of Brain Lesions
-------------------------------------------------------------------------------------

POVZETEK:

A brain lesion is an area of tissue injury or disease within the brain. Brain-imaging techniques, such as MRI, produce images of the brain used for diagnosis or prognosis of a wide variety of injuries or conditions. Such images can be used to classify brain lesions. Recently, neural networks have been used to great success in different computer vision domains, including brain image processing. In this work, we develop a convolutional neural network that automatically classifies MRI images in multiple sclerosis patients. The image dataset consists of three-dimensional images with three channels: FLAIR MRI, QSM MRI, and a mask channel indicating lesion location. We describe data augmentation techniques we use for increasing the dataset and present the network architecture and the results of the model. Specifically, we show the results of training the network using different combinations of the three image channels.

ČAS/PROSTOR: 16. maj 2022 ob 16.00 na daljavo

-----------------------------------------
PREDAVATELJ: Vanja MILESKI
-----------------------------------------

After graduating from the Faculty of Computer and Information Science at the University of Ljubljana in 2015, Vanja Mileski started working at the Jožef Stefan Institute (JSI). He was a Master's student at the International Postgraduate School Jožef Stefan and a student researcher at the JSI. After finishing his Master's studies, he applied his knowledge of data mining in the private sector as a Data Scientist in the retail, telecommunications, banking, stock market and insurance sectors.
His current research interests include time-series classification, deep learning, ResNet and Inception architectures.

----------------------------------------------------------------------------------------------------------------
NASLOV: Deep learning for time series data using Inception and ResNet paradigms
----------------------------------------------------------------------------------------------------------------

POVZETEK:

With the advancements in Convolutional Neural Network (CNN) architectures such as Inception modules and ResNet architectures, it is of particular interest to study these advances and apply them on time series data. Time series features can be viewed as one-dimensional vectors, on which we can apply different types of filters using Inception modules, and then train a deeper network using a ResNet-like architecture. We propose an idea of combining these advancements and testing them on real-life data of customer shopping habits obtained from a large retailer in Slovenia with the hopes of beating traditional ML techniques.
