FUSION is a family of multimodal large language models that adopts a fully integrated vision-language architecture, enabling comprehensive and fine-grained cross-modal understanding. In contrast to prior approaches that primarily perform shallow or late-stage modality fusion during the LLM decoding phase, FUSION achieves deep, dynamic integration across the entire vision-language processing pipeline.
|
| 23 |
+
|
| 24 |
+
To enable this, FUSION utilizes Text-Guided Unified Vision Encoding, which incorporates textual context directly into the vision encoder. This design allows for pixel-level vision-language alignment and facilitates early-stage cross-modal interaction.
|
| 25 |
+
|
| 26 |
+
During decoding, FUSION employs Context-Aware Recursive Alignment Decoding strategy. This component dynamically aggregates and refines visual features based on the evolving textual context at each decoding step, allowing the model to capture question-level semantics with high precision.
|
| 27 |
+
|
| 28 |
+
To further enhance alignment and reduce the semantic gap between modalities, FUSION integrates Dual-Supervised Semantic Mapping Loss, which provides simultaneous supervision in both visual and textual embedding spaces. This dual-path guidance strengthens the consistency and semantic coherence of the fused representations.

## Training Details

+
**Training Strategies**
|
| 39 |
+
|
| 40 |
+
FUSION is trained with a three-stage training framework, ensuring comprehensive alignment and integration between visual and linguistic modalities.
|
| 41 |
+
|
| 42 |
+
- **Stage1: Foundational Semantic Alignment**: We pretrain the vision encoder using extensive image-caption datasets to establish precise semantic alignment be- tween visual and textual representations.
|
| 43 |
+
- **Stage1.5: Contextual Multimodal Fusion**: In contrast to Stage 1, this intermediate stage incorporates various types of QA data along with image-caption pairs. This phase is designed to enhance the model’s adaptability in aligning vision and language representations across a broad spectrum of scenarios.
|
| 44 |
+
- **Stage2: Visual Instruction Tuning**: At this stage, we expose the model to various visual tasks, enabling it to answer downstream vision-related questions effectively.
|
| 45 |
