Causality-Induced Positional Encoding for Transformer-Based Representation Learning of Non-Sequential Features

NeurIPS 2025poster

Positional encoding is essential for supplementing transformer with positional information of tokens. Existing positional encoding methods demand predefined token/feature order, rendering them unsuitable for real-world data with non-sequential yet causally-related features. To address this limitatio…

MEATRD: Multimodal Anomalous Tissue Region Detection Enhanced with Spatial Transcriptomics

AAAI 2025technical

The detection of anomalous tissue regions (ATRs) within affected tissues is crucial in clinical diagnosis and pathological studies. Conventional automated ATR detection methods, primarily based on histology images alone, falter in cases where ATRs and normal tissues have subtle visual differences. T…

Domain Adaptive and Fine-grained Anomaly Detection for Single-cell Sequencing Data and Beyond

IJCAI 2024poster

Fined-grained anomalous cell detection from affected tissues is critical for clinical diagnosis and pathological research. Single-cell sequencing data provide unprecedented opportunities for this task. However, current anomaly detection methods struggle to handle domain shifts prevalent in multi-sam…

Soft Robot Skin With Conformal Adaptability for On-Body Tactile Perception of Collaborative Robots

RA-L 2022

Robot skin, as the physical interface between collaborative robots (cobots) and the external environments, could mediate on-body tactile signals for cobots to respond timely once a collision occurs during tasks and thus avoid damages to both cobots and surroundings. To achieve effective on-body tact
