SHIFT15M: Fashion-specific dataset for set-to-set matching with several distribution shifts

2 code implementations30 Aug 2021 Masanari Kimura, Takuma Nakamura, Yuki Saito

This paper addresses the problem of set-to-set matching, which involves matching two different sets of items based on some criteria, especially in the case of high-dimensional items like images.

$α$-Geodesical Skew Divergence

1 code implementation31 Mar 2021 Masanari Kimura, Hideitsu Hino

The asymmetric skew divergence smooths one of the distributions by mixing it, to a degree determined by the parameter $\lambda$, with the other distribution.

Node Centralities and Classification Performance for Characterizing Node Embedding Algorithms

1 code implementation18 Feb 2018 Kento Nozawa, Masanari Kimura, Atsunori Kanemura

Embedding graph nodes into a vector space can allow the use of machine learning to e. g. predict node classes, but the study of node embedding algorithms is immature compared to the natural language processing field because of a diverse nature of graphs.

A Short Survey on Importance Weighting for Machine Learning

no code implementations15 Mar 2024 Masanari Kimura, Hideitsu Hino

Importance weighting is a fundamental procedure in statistics and machine learning that weights the objective function or probability distribution based on the importance of the instance in some sense.

On permutation-invariant neural networks

no code implementations26 Mar 2024 Masanari Kimura, Ryotaro Shimizu, Yuki Hirakawa, Ryosuke Goto, Yuki Saito

From these observations, we show that Deep Sets, one of the well-known permutation-invariant neural networks, can be generalized in the sense of a quasi-arithmetic mean.
