Minimax Optimal Estimation of Transport-Growth Pairs in Unbalanced Optimal Transport
Donlapark Ponnoprat, Noboru Isobe, Masaaki Imaizumi
Unbalanced optimal transport (UOT) extends classical optimal transport to measures with different total masses, but statistical guarantees for Monge-type estimation remain limited.…
Conditional Counterfactual Mean Embeddings: Doubly Robust Estimation and Learning Rates
Thatchanon Anancharoenkij, Donlapark Ponnoprat
A complete understanding of heterogeneous treatment effects involves characterizing the full conditional distribution of potential outcomes. To this end, we propose the Conditional…
Counting Graphlets of Size under Local Differential Privacy
Vorapong Suppakitpaisarn, Donlapark Ponnoprat, Nicha Hirankarn +1
The problem of counting subgraphs or graphlets under local differential privacy is an important challenge that has attracted significant attention from researchers. However, much o…
Minimax Rates of Estimation for Optimal Transport Map between Infinite-Dimensional Spaces
Donlapark Ponnoprat, Masaaki Imaizumi
We investigate the estimation of an optimal transport map between probability measures on an infinite-dimensional space and reveal its minimax optimal rate. Optimal transport theor…

Panisara Meehinkong, Donlapark Ponnoprat
Conformal prediction provides a framework for uncertainty quantification, specifically in the forms of prediction intervals and sets with distribution-free guaranteed coverage. Whi…
Investigating Privacy Leakage in Dimensionality Reduction Methods via Reconstruction Attack
Chayadon Lumbut, Donlapark Ponnoprat
This study investigates privacy leakage in dimensionality reduction methods through a novel machine learning-based reconstruction attack. Employing an informed adversary threat mod…
Uniform Confidence Band for Optimal Transport Map on One-Dimensional Data
Donlapark Ponnoprat, Ryo Okano, Masaaki Imaizumi
We develop a statistical inference method for an optimal transport map between distributions on real numbers with uniform confidence bands. The concept of optimal transport (OT) is…
Developing A Visual-Interactive Interface for Electronic Health Record Labeling: An Explainable Machine Learning Approach
Donlapark Ponnoprat, Parichart Pattarapanitchai, Phimphaka Taninpong +3
Labeling a large number of electronic health records is expensive and time consuming, and having a labeling assistant tool can significantly reduce medical experts' workload. Never…
Detecting Anomalous LAN Activities under Differential Privacy
Norrathep Rattanavipanon, Donlapark Ponnoprat, Hideya Ochiai +3
Anomaly detection has emerged as a popular technique for detecting malicious activities in local area networks (LANs). Various aspects of LAN anomaly detection have been widely stu…
Dirichlet Mechanism for Differentially Private KL Divergence Minimization
Donlapark Ponnoprat
Given an empirical distribution of sensitive data , we consider the task of minimizing over a probability simplex, while protecting t…
Universal consistency of Wasserstein -NN classifier: Negative and Positive Results
Donlapark Ponnoprat
The Wasserstein distance provides a notion of dissimilarities between probability measures, which has recent applications in learning of structured data with varying size such as i…
