VLM

Qwen-VL is a vision-language model series launched by Alibaba DAMO Academy, extended from the Qwen large language model, adopting a combined architecture of a ViT visual encoder and the Qwen language model, and achieving cross-modal alignment through a position-aware visual-language adapter.

VLMs (Vision Language Models) typically consist of a visual encoder (such as ViT), a language model, and a projection layer connecting the two, with representative models including GPT-4V/4o, Claude 3.5, the LLaVA series, and InternVL

Vision-language models (VLMs) can simultaneously process image and text information and establish semantic associations between the two.

The typical architecture of a VLM (Vision-Language Model) consists of three core components: a visual encoder (such as ViT), a language model (typically a large language model), and a projection layer or adapter module connecting the two.

A VLM consists of three components: a visual encoder, a language model backbone, and a cross-modal alignment module.

A VLM (vision-language model) is a type of model that simultaneously accepts image and text inputs and performs reasoning in a shared representation space.

Unlike traditional RPA, which relies on pre-recorded coordinate scripts, computer use based on vision-language models can understand interface semantics and has stronger generalization capabilities.

The architectural core of a multimodal large model must include a large language model (LLM) as its backbone.

Security surveillance target retrieval, detection of minute lesions in medical imaging, and satellite image analysis share common technical challenges: extremely small target-to-image ratios, strong background interference, and extremely low tolerance for missed detections.

In accuracy-sensitive scenarios, 7B-scale large-model VLMs still have value relative to GUI-JEPA (an 86% to 92% accuracy retention rate implies an 8% to 14% accuracy loss).

Traditional 7-billion-parameter-scale VLM GUI agents suffer from inference speed limited by autoregressive decoding and high deployment costs due to large models residing in memory.

The Dwell framework recasts the VLM as a recurrent latent transition operator, enabling the model to play both the role of world model and policy.

Traditional VLMs take vision as input and language as output; visual information is used only once at the input stage, and the reasoning process occurs entirely in language space.

The paper proposes a self-evolution method that improves VLM performance by searching reasoning programs and model-surrounding code, raising average accuracy from 16.6% to 41.3%.

In scientific chart question answering, VLMs must complete multi-level subtasks such as OCR, legend recognition, axis reading, numerical comparison, and arithmetic reasoning, and a deviation in any step can cause the final answer to mismatch the ground-truth answer.

The evaluated VLM itself remains completely frozen, and all optimization occurs at the level of the reasoning program and surrounding code, requiring no gradient updates, additional training data, or modification of model weights.

Three VLMs all improved in exact-match rate on four scientific chart benchmarks, with a single maximum improvement of 55.2 percentage points.

The paper's conclusion states that a considerable portion of the observed errors originates in the reasoning pipeline itself, and optimizing the pipeline can improve the performance of a frozen VLM without retraining.
