A Fashion Item Recommendation Model in Hyperbolic Space

Ryotaro Shimizu, Yu Wang, Masanari Kimura +4

In this work, we propose a fashion item recommendation model that incorporates hyperbolic geometry into user and item representations. Using hyperbolic space, our model aims to cap…

Explaining Black-box Model Predictions via Two-level Nested Feature Attributions with Consistency Property

Yuya Yoshikawa, Masanari Kimura, Ryotaro Shimizu +1

Techniques that explain the predictions of black-box machine learning models are crucial to make the models transparent, thereby increasing trust in AI systems. The input features…

On permutation-invariant neural networks

Masanari Kimura, Ryotaro Shimizu, Yuki Hirakawa +2

Conventional machine learning algorithms have traditionally been designed under the assumption that input data follows a vector-based format, with an emphasis on vector-centric par…

A Short Survey on Importance Weighting for Machine Learning

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 in…

Understanding Test-Time Augmentation

Masanari Kimura

Test-Time Augmentation (TTA) is a very powerful heuristic that takes advantage of data augmentation during testing to produce averaged output. Despite the experimental effectivenes…

Information Geometrically Generalized Covariate Shift Adaptation

Masanari Kimura, Hideitsu Hino

Many machine learning methods assume that the training and test data follow the same distribution. However, in the real world, this assumption is very often violated. In particular…

Generalization Bounds for Set-to-Set Matching with Negative Sampling

Masanari Kimura

The problem of matching two sets of multiple elements, namely set-to-set matching, has received a great deal of attention in recent years. In particular, it has been reported that…

Fashion-Specific Attributes Interpretation via Dual Gaussian Visual-Semantic Embedding

Ryotaro Shimizu, Masanari Kimura, Masayuki Goto

Several techniques to map various types of components, such as words, attributes, and images, into the embedded space have been studied. Most of them estimate the embedded represen…

-Geodesical Skew Divergence

Masanari Kimura, Hideitsu Hino

The asymmetric skew divergence smooths one of the distributions by mixing it, to a degree determined by the parameter , with the other distribution. Such divergence is an approx…
