What is colsmolvlm-alpha?
ColSmolVLM-alpha is an innovative visual language model designed for efficient document retrieval. It extends SmolVLM by incorporating ColBERT-style multi-vector representations for both text and images. This version was trained with a batch size of 128 for 3 epochs, utilizing the PEFT (Parameter Efficient Fine-Tuning) approach with LoRA adapters.
Implementation Details
The model employs bfloat16 format and uses LoRA with alpha=32 and r=32 on transformer layers. It's trained using a paged_adamw_8bit optimizer on a 4 GPU setup with data parallelism, featuring a learning rate of 5e-4 with linear decay and 2.5% warmup steps.
- Trained on 127,460 query-page pairs (63% academic datasets, 37% synthetic data)
- Uses flash attention 2 for efficient processing
- Implements ColBERT late interaction mechanism
Core Capabilities
- Multi-vector representation generation for both text and images
- Efficient document indexing from visual features
- Zero-shot generalization to non-English languages
- PDF document processing and retrieval
