HiFC-GAN: Hierarchical Feature-Constrained GAN for Optical-to-SAR Transfer in SAR Target Classification

AAAI 2026technical

The limited availability of high-quality training data poses a persistent challenge for synthetic aperture radar (SAR) target classification. Existing data augmentation methods mainly adopt a simplistic application of GAN-based style transfer techniques to directly synthesize pseudo-SAR images from

Intra-Class Unbiased Prototype Aggregation and Classifier Collaboration for Personalized Federated Learning

AAAI 2026technical

Prototype-based personalized federated learning methods have emerged as a promising strategy due to their ability to represent client-specific class characteristics effectively through learned class prototypes. These prototypes capture salient features of client-local data, facilitating personalized

Revisiting the Data Sampling in Multimodal Post-training from a Difficulty-Distinguish View

AAAI 2026technical

Recent advances in Multimodal Large Language Models (MLLMs) have spurred significant progress in Chain-of-Thought (CoT) reasoning. Building on the success of Deepseek-R1, researchers extended multimodal reasoning to post-training paradigms based on reinforcement learning (RL), focusing predominantly

AIDC: Benchmark for Analytical Learning in Incremental Disease Classification

ICASSP 2025accepted

Class Incremental Learning (CIL) aims to enable models to continuously learn new categories while retaining previous classification abilities. In medical scenarios, where new disease categories frequently emerge, CIL becomes crucial. Traditional CIL approaches often face "catastrophic forgetting". A…

EGDCL: An Adaptive Curriculum Learning Framework for Unbiased Glaucoma Diagnosis

ECCV 2020poster

Today's computer-aided diagnosis (CAD) model is still far from the clinical practice of glaucoma detection, mainly due to the training bias originating from 1) the normal-abnormal class imbalance and 2) the rare but significant hard samples in fundus images. However, debiasing in CAD is not trivial…

Improving Knowledge Distillation via Category Structure

ECCV 2020poster

Most previous knowledge distillation frameworks train the student to mimic the teacher's output of each sample or transfer cross-sample relations from the teacher to the student. Nevertheless, they neglect the structured relations at a category level. In this paper, a novel Category Structure is pro…
