MYOPIA: Understanding the Limits of Tree-Based Reasoning in Vision-Language Models

Tree-Based Reasoning in Vision-Language Models MYOPIA is a benchmark for testing whether vision-language models (VLMs) classify images better when they follow a human-designed decision tree, one question at a time, than when they are asked for the label directly (zero-shot).

MYOPIA: Understanding the Limits of Tree-Based Reasoning in Vision-Language Models

MYOPIA is a benchmark for testing whether vision-language models (VLMs) classify images better when they follow a human-designed decision tree, one question at a time, than when they are asked for the label directly (zero-shot). It provides:

Four fixed evaluation subsets: GTSRB (901 images, 43 classes), MNIST (1,000, 10), CIFAR-10 (1,000, 10), and single-object MSCOCO (850, 90).
