Self-Supervised Transformers for fMRI representation

Itzik Malkiel, Gony Rosenman, Lior Wolf +1

We present TFF, which is a Transformer framework for the analysis of functional Magnetic Resonance Imaging (fMRI) data. TFF employs a two-phase training approach. First, self-super…

Caption Enriched Samples for Improving Hateful Memes Detection

Efrat Blaier, Itzik Malkiel, Lior Wolf

The recently introduced hateful meme challenge demonstrates the difficulty of determining whether a meme is hateful or not. Specifically, both unimodal language models and multimod…

GAM: Explainable Visual Similarity and Classification via Gradient Activation Maps

Oren Barkan, Omri Armstrong, Amir Hertz +4

We present Gradient Activation Maps (GAM) - a machinery for explaining predictions made by visual similarity and classification models. By gleaning localized gradient and activatio…

Self-Supervised Document Similarity Ranking via Contextualized Language Models and Hierarchical Inference

Dvir Ginzburg, Itzik Malkiel, Oren Barkan +2

We present a novel model for the problem of ranking a collection of documents according to their semantic similarity to a source (query) document. While the problem of document-to-…

Adaptive Gradient Balancing for Undersampled MRI Reconstruction and Image-to-Image Translation

Itzik Malkiel, Sangtae Ahn, Valentina Taviani +3

Recent accelerated MRI reconstruction models have used Deep Neural Networks (DNNs) to reconstruct relatively high-quality images from highly undersampled k-space data, enabling muc…
