Learning Query Expansion over the Nearest Neighbor Graph

no code implementations5 Dec 2021 Benjamin Klein, Lior Wolf

In this work, a hierarchical model, Graph Query Expansion (GQE), is presented, which is learned in a supervised manner and performs aggregation over an extended neighborhood of the query, thus increasing the information used from the database when computing the query expansion, and using the structure of the nearest neighbors graph.

End-to-End Supervised Product Quantization for Image Search and Retrieval

no code implementations CVPR 2019 Benjamin Klein, Lior Wolf

To our knowledge, this is the first work to introduce a dictionary-based representation that is inspired by Product Quantization and which is learned end-to-end, and thus benefits from the supervised signal.

Associating Neural Word Embeddings With Deep Image Representations Using Fisher Vectors

no code implementations CVPR 2015 Benjamin Klein, Guy Lev, Gil Sadeh, Lior Wolf

In this work, we are using the Fisher Vector as a sentence representation by pooling the word2vec embedding of each word in the sentence.

A Dynamic Convolutional Layer for Short Range Weather Prediction

no code implementations CVPR 2015 Benjamin Klein, Lior Wolf, Yehuda Afek

In contrast, the dynamic convolutional layer uses filters that will vary from input to input during testing.

Fisher Vectors Derived from Hybrid Gaussian-Laplacian Mixture Models for Image Annotation

no code implementations26 Nov 2014 Benjamin Klein, Guy Lev, Gil Sadeh, Lior Wolf

The second Mixture Model presented is a Hybrid Gaussian-Laplacian Mixture Model (HGLMM) which is based on a weighted geometric mean of the Gaussian and Laplacian distribution.
