Focused Training: The cross-attention blocks and Perceiver Resampler are specifically trained to integrate visual embeddings with textual data.
Component-Freezing: While these components are trained, other parts of the model remain frozen, allowing for focused enhancement of the integration process.
LLaVA Training Methodology
LLaVA's training methodology is designed to refine the multimodal LLM through a two-stage process, ensuring that the model excels in visual and textual tasks.
The significant steps in LLaVA's training include:
Stage 1: Image Captioning with Frozen Vision Encoder and LLM
Initial Training: The first stage involves training the model on image captioning tasks while keeping the vision encoder and the language model frozen.
Capturing Details: This stage ensures that the model learns to describe images accurately, laying a solidfoundation for integrating visual and textual data.
Stage 2: Fine-Tuning on Synthetic Instruction-Following Dataset
Instruction Following: In the second stage, LLaVA is fine-tuned on a synthetic dataset designed for instruction-following tasks.
Enhancing Precision: This fine-tuning improves the model's ability to follow and respond to detailed instructions, making it more effective in real-world applications. It is crucial to ensure AI meets regulatory compliance standards. In the real world both visual and textual data are involved, such as generating bookkeeping tips from mixed-media inputs.
The training methodologies behind Flamingo and LLaVA illustrate the careful planning and execution required to create powerful multimodal LLMs. These methodologies ensure that the models are not only accurate but also versatile and capable of handling diverse data types with equal proficiency.
During the second stage of LLaVA's training, the fine-tuning process on a synthetic instruction-following dataset becomes crucial, particularly in refining the model's ability to handle complex tasks. This stage is akin to what is demonstrated in RagaAI Catalyst which tests and fixes all issues in your LLM Application, where fine-tuning plays a vital role in ensuring the model's effectiveness in real-world scenarios.
