PINet: Improving the Stability of Prototype Networks via Phantasia-Inspired Uncertain Representations

AAAI 2026technical

Self-interpretable models are increasingly valued for their inherent explainability. Among them, part-prototype networks stand out by mimicking human reasoning through the use of learned prototypes. However, their explanations often lack stability, becoming sensitive to subtle input perturbations. I

Shifted Flow Policy: Uncertainty-Aware Time Reparameterization for Visuomotor Learning

ICRA 2026poster

Imitation learning for robotics often uses action chunking to mitigate the compounding errors associated with autoregressive policies. By predicting multiple future actions simultaneously, action chunking limits the accumulation of errors but introduces new difficulties. In particular, it relies on …

Scene Graph Generation Strategy with Co-occurrence Knowledge and Learnable Term Frequency

ICML 2024poster

Scene graph generation (SGG) is an important task in image understanding because it represents the relationships between objects in an image as a graph structure, making it possible to understand the semantic relationships between objects intuitively. Previous SGG studies used a message-passing neur…

ViT-NeT: Interpretable Vision Transformers with Neural Tree Decoder

ICML 2022spotlight

Vision transformers (ViTs), which have demonstrated a state-of-the-art performance in image classification, can also visualize global interpretations through attention-based contributions. However, the complexity of the model makes it difficult to interpret the decision-making process, and the ambig…
