Researchers have developed ENCORE, a novel framework designed to enhance the performance of Vision-Language Models (VLMs). ENCORE addresses limitations in current transformer-based visual encoders by preserving object integrity, particularly in lightweight VLMs. The framework incorporates an Entropy-based Cropping Strategy (ECS) during inference to select image crops with minimal entropy, thereby maintaining prompt-relevant regions. Additionally, it uses Entropy Regularization Training (ERT) during training to focus attention on key visual tokens. Experiments on ten VQA benchmarks demonstrate that ENCORE achieves a 1.43% average accuracy gain and sets a new state-of-the-art for 2B-parameter VLMs, with only a 0.14% parameter fine-tuning. AI
IMPACT Enhances VLM performance by improving object integrity and attention, potentially setting new benchmarks for smaller models.
