Hyperbolic PHATE: Visualizing Continuous Hierarchy of Latent Differentiation Structures

ICASSP 2025accepted

This paper proposes a method for embedding diffusion potentials into a hyperbolic space in order to visualize the differentiation structure consisting of diffusion and branching inherent in high-dimensional data. In recent years, the rapid development of single-cell sequencing in the field of biolog…

Warped Diffusion for Latent Differentiation Inference

AISTATS 2024poster

This paper proposes a Bayesian nonparametric diffusion model with a black-box warping function represented by a Gaussian process to infer potential diffusion structures latent in observed data, such as differentiation mechanisms of living cells and phylogenetic evolution processes of media informati…

Nonparametric Relational Models with Superrectangulation

AISTATS 2022poster

This paper addresses the question, ”What is the smallest object that contains all rectangular partitions with n or fewer blocks?” and shows its application to relational data analysis using a new strategy we call super Bayes as an alternative to Bayesian nonparametric (BNP) methods. Conventionally,…

Permuton-induced Chinese Restaurant Process

NeurIPS 2021poster

This paper proposes the permuton-induced Chinese restaurant process (PCRP), a stochastic process on rectangular partitioning of a matrix. This distribution is suitable for use as a prior distribution in Bayesian nonparametric relational model to find hidden clusters in matrices and network data. Our…

Machine Learning Based Skill-Level Classification for Personal Mobility Devices Using Only Operational Characteristics

IROS 2018poster

Some electric-powered wheelchairs are recently redefined as personal mobility devices. Their users are not only elderly or handicapped people, but also passengers with large baggage or pedestrians going from station to destination, i.e., last-mile transport. Consequently, people with different opera…
