Confusion-Aware Spectral Regularizer for Long-Tailed Recognition

CVPR 2026

Long-tailed image classification remains a long-standing challenge, as real-world data typically follow highly imbalanced distributions where a few head classes dominate and many tail classes contain only limited samples. This imbalance biases feature learning toward head categories and leads to sig

Dual-Kernel Adapter: Expanding Spatial Horizons for Data-Constrained Medical Image Analysis

ICLR 2026poster

Adapters have become a widely adopted strategy for efficient fine-tuning of foundation models, particularly in resource-constrained settings. However, their performance under extreme data scarcity—common in medical imaging due to high annotation costs, privacy regulations, and fragmented datasets—re…

SPAM: Spike-Aware Adam with Momentum Reset for Stable LLM Training

ICLR 2025poster

Large Language Models (LLMs) have demonstrated exceptional performance across diverse tasks, yet their training remains highly resource intensive and susceptible to critical challenges such as training instability. A predominant source of this instability stems from gradient and loss spikes, which d…
