Ran Balicer - AI-Driven Healthcare: Innovation in practice

מערכות בריאות בעולם הולכות ומפנימות שהסטטוס קוו אינו בר קיימא, ושנדרש עיצוב מחדש של שירותי הבריאות בעידן הנוכחי.

ההתקדמות הטכנולוגית המואצת מייצרת הזדמנויות אך המערכות הנוקשות מתקשות להסתגל.

Tal Shapira - FlowPic: Encrypted Internet Traffic Classification is as Easy as Image Recognition

Internet traffic classification has been intensively studied over the past decade due to its importance for traffic engineering and cyber security. However, identifying the type of a network flow or a specific application become harder in recent years due to the use of encryption, e.g., by VPN and Tor.

Teddy Lazebnik: A SAT-Pruned Explainable Machine Learning Model To Predict Acute Kidney Injury Following Open Partial Nephrectomy Treatment

A decision tree (DT) is one of the most popular and efficient techniques in data mining. Specifically, in the clinical domain, DTs have been widely used thanks to their relatively easy explainable nature, efficient computation time, and relatively accurate predictions. However, some DT constriction algorithms may produce a large tree-size structure which is difficult to understand and often leads to misclassification of data in the testing process due to poor generalization.

Meitar Ronen - DeepDPM: Deep Clustering With an Unknown Number of Clusters

Deep Learning (DL) has shown great promise in the unsupervised task of clustering. That said, while in classical (i.e., non-deep) clustering the benefits of the nonparametric approach are well known, most deep-clustering methods are parametric: namely, they require a predefined and fixed number of clusters, denoted by K. When K is unknown, however, using model-selection criteria to choose its optimal value might become computationally expensive, especially in DL as the training process would have to be repeated numerous times.

Ben Galili - From Stable Statistics to Robust Differentially Expressed Genes

Statistical hypothesis test is a fundamental tool in statistics, where one can determine whether to accept or reject the null hypothesis (the default statement of no difference). Rejecting the null hypothesis means that the probability of getting the observed results is very low - lower than a predetermined significance level. This probability is called a p-value and the lower the p-value is the more significant the results.

Nati Linial - Graphs as geometric objects

Many of the basic algorithmic questions deal with the geometry of graphs. We know many variations on the theme of computing the metric of edge-weighted graphs. E.g., “all-pairs shortest paths”. As I will try to convey in this lecture, there is much that we know beyond that as well as broad barely charted territories. For example, let G=(V,E) be a graph and let w(e)>0 be given positive real numbers associated with every edge e in E.
