Text-Guided Few-Shot Semantic Segmentation with Training-Free Multimodal Feature Matching

ICASSP 2025accepted

This paper addresses few-shot semantic segmentation (FSS) guided by text, where we classify unseen novel classes using image and text references as in-context examples, without the need for training. We enhance the quality and stability of the segmentation masks generated by FSS by combining the cap…

A Surprisingly Simple Approach to Generalized Few-Shot Semantic Segmentation

NeurIPS 2024poster

The goal of *generalized* few-shot semantic segmentation (GFSS) is to recognize *novel-class* objects through training with a few annotated examples and the *base-class* model that learned the knowledge about the base classes. Unlike the classic few-shot semantic segmentation, GFSS aims to classify…

Probabilistic Feature Matching for Fast Scalable Visual Prompting

IJCAI 2024poster

In this work, we propose a novel framework for image segmentation guided by visual prompting which leverages the power of vision foundation models. Inspired by recent advancements in computer vision, our approach integrates multiple large-scale pretrained models to address the challenges of segment…

Cumulative Stay-time Representation for Electronic Health Records in Medical Event Time Prediction

IJCAI 2022poster

We address the problem of predicting when a disease will develop, i.e., medical event time (MET), from a patient's electronic health record (EHR). The MET of non-communicable diseases like diabetes is highly correlated to cumulative health conditions, more specifically, how much time the patient sp…

Hierarchical Lattice Layer for Partially Monotone Neural Networks

NeurIPS 2022accept

Partially monotone regression is a regression analysis in which the target values are monotonically increasing with respect to a subset of input features. The TensorFlow Lattice library is one of the standard machine learning libraries for partially monotone regression. It consists of several neu…

Variational Inference for Discriminative Learning with Generative Modeling of Feature Incompletion

ICLR 2022oral

We are concerned with the problem of distributional prediction with incomplete features: The goal is to estimate the distribution of target variables given feature vectors with some of the elements missing. A typical approach to this problem is to perform missing-value imputation and regression, sim…

Learning to Estimate Driver Drowsiness from Car Acceleration Sensors Using Weakly Labeled Data

ICASSP 2020accepted

This paper addresses the learning task of estimating driver drowsiness from the signals of car acceleration sensors. Since even drivers themselves cannot perceive their own drowsiness in a timely manner unless they use burdensome invasive sensors, obtaining labeled training data for each timestamp i…

Consistent and Efficient Nonparametric Different-Feature Selection

AISTATS 2017poster

Two-sample feature selection is a ubiquitous problem in both scientific and engineering studies. We propose a feature selection method to find features that describe a difference in two probability distributions. The proposed method is nonparametric and does not assume any specific parametric models…
