Denoising Cosine Similarity: A Theory-Driven Approach for Efficient Representation Learning

no code implementations19 Apr 2023 Takumi Nakagawa, Yutaro Sanada, Hiroki Waida, Yuhui Zhang, Yuichiro Wada, Kōsaku Takanashi, Tomonori Yamada, Takafumi Kanamori

To this end, inspired by recent works on denoising and the success of the cosine-similarity-based objective functions in representation learning, we propose the denoising Cosine-Similarity (dCS) loss.

Denoising Representation Learning

Equivariant online predictions of non-stationary time series

no code implementations20 Nov 2019 Kōsaku Takanashi, Kenichiro McAlinn

To analyze the theoretical predictive properties of statistical methods under this setting, we first define the Kullback-Leibler risk, in order to place the problem within a decision theoretic framework.
