Unintended Effects on Adaptive Learning Rate for Training Neural Network with Output Scale Change

Ryuichi Kanoh, Mahito Sugiyama

A multiplicative constant scaling factor is often applied to the model output to adjust the dynamics of neural network parameters. This has been used as one of the key intervention…

Fast Tucker Rank Reduction for Non-Negative Tensors Using Mean-Field Approximation

Kazu Ghalamkari, Mahito Sugiyama

We present an efficient low-rank approximation algorithm for non-negative tensors. The algorithm is derived from our two findings: First, we show that rank-1 approximation for tens…

Additive Poisson Process: Learning Intensity of Higher-Order Interaction in Stochastic Processes

Simon Luo, Feng Zhou, Lamiae Azizi +1

We present the Additive Poisson Process (APP), a novel framework that can model the higher-order interaction effects of the intensity functions in stochastic processes using lower…

Fast Rank Reduction for Non-negative Matrices via Mean Field Theory

Kazu Ghalamkari, Mahito Sugiyama

We propose an efficient matrix rank reduction method for non-negative matrices, whose time complexity is quadratic in the number of rows or columns of a matrix. Our key insight is…

Double Descent Risk and Volume Saturation Effects: A Geometric Perspective

Prasad Cheema, Mahito Sugiyama

The appearance of the double-descent risk phenomenon has received growing interest in the machine learning and statistics community, as it challenges well-understood notions behind…

Bias-Variance Trade-Off in Hierarchical Probabilistic Models Using Higher-Order Feature Interactions

Simon Luo, Mahito Sugiyama

Hierarchical probabilistic models are able to use a large number of parameters to create a model with a high representation power. However, it is well known that increasing the num…
