A Black-Box Attack Model for Visually-Aware Recommender Systems
Rami Cohen, Oren Sar Shalom, Dietmar Jannach +1
Due to the advances in deep learning, visually-aware recommender systems (RS) have recently attracted increased research interest. Such systems combine collaborative signals with i…
Understanding Convolutional Neural Networks for Text Classification
Alon Jacovi, Oren Sar Shalom, Yoav Goldberg
We present an analysis into the inner workings of Convolutional Neural Networks (CNNs) for processing text. CNNs used for computer vision can be interpreted by projecting filters i…
Rank and Rate: Multi-task Learning for Recommender Systems
Guy Hadash, Oren Sar Shalom, Rita Osadchy
The two main tasks in the Recommender Systems domain are the ranking and rating prediction tasks. The rating prediction task aims at predicting to what extent a user would like any…
Privacy and Fairness in Recommender Systems via Adversarial Training of User Representations
Yehezkel S. Resheff, Yanai Elazar, Moni Shahar +1
Latent factor models for recommender systems represent users and items as low dimensional vectors. Privacy risks of such systems have previously been studied mostly in the context…
