The Hidden Attention of Mamba Models

1 code implementation3 Mar 2024 Ameen Ali, Itamar Zimerman, Lior Wolf

The Mamba layer offers an efficient selective state space model (SSM) that is highly effective in modeling multiple domains, including NLP, long-range sequence processing, and computer vision.

Degree-based stratification of nodes in Graph Neural Networks

no code implementations16 Dec 2023 Ameen Ali, Hakan Cevikalp, Lior Wolf

Here, we propose a different approach that is based on a stratification of the graph nodes.

Centered Self-Attention Layers

no code implementations2 Jun 2023 Ameen Ali, Tomer Galanti, Lior Wolf

The self-attention mechanism in transformers and the message-passing mechanism in graph neural networks are repeatedly applied within deep learning architectures.

Video and Text Matching with Conditioned Embeddings

1 code implementation21 Oct 2021 Ameen Ali, Idan Schwartz, Tamir Hazan, Lior Wolf

Traditionally video and text matching is done by learning a shared embedding space and the encoding of one modality is independent of the other.

Weakly Supervised Recovery of Semantic Attributes

no code implementations22 Mar 2021 Ameen Ali, Tomer Galanti, Evgeniy Zheltonozhskiy, Chaim Baskin, Lior Wolf

We consider the problem of the extraction of semantic attributes, supervised only with classification labels.

Visualization of Supervised and Self-Supervised Neural Networks via Attribution Guided Factorization

1 code implementation3 Dec 2020 Shir Gur, Ameen Ali, Lior Wolf

However, as we show, these methods are limited in their ability to identify the support for alternative classifications, an effect we name {\em the saliency bias} hypothesis.
