# Self-Supervised Multimodal Learning
|
| 2 |
+
|
| 3 |
+
## Abstract
|
| 4 |
+
|
| 5 |
+
Recent advances in multimodal learning have opened new possibilities. We build on these developments to address self-supervised multimodal learning. Our experiments demonstrate improvements over baseline approaches across multiple benchmarks. We release code and models for reproducibility.
|
| 6 |
+
|
| 7 |
+
## 1. Introduction
|
| 8 |
+
|
| 9 |
+
Multimodal learning has become a central topic in machine learning research. The ability to process and reason across different modalities — images, text, audio — has enabled applications ranging from image captioning to visual question answering.
|
| 10 |
+
|
| 11 |
+
However, scaling multimodal models presents unique challenges. The interplay between modality-specific encoders and cross-modal fusion layers creates a complex design space. In this paper, we focus on self-supervised multimodal learning and make the following contributions:
|
| 12 |
+
|
| 13 |
+
- A novel approach to cross-modal feature alignment
|
| 14 |
+
- An efficient training procedure that reduces computational cost
|
| 15 |
+
- Comprehensive experiments across multiple datasets and settings
|
| 16 |
+
|
| 17 |
+
## 2. Background
|
| 18 |
+
|
| 19 |
+
Several lines of research inform our work. Vision-language pretraining methods such as CLIP and BLIP demonstrated that contrastive objectives on image-text pairs yield strong transferable representations. Subsequent work explored different fusion strategies, including cross-attention and co-attention mechanisms.
|
| 20 |
+
|
| 21 |
+
On the efficiency side, recent progress in attention mechanisms — including linear attention, sparse attention, and flash attention — has made it feasible to train smaller models that remain competitive.
|
| 22 |
+
|
| 23 |
+
## 3. Method
|
| 24 |
+
|
| 25 |
+
### 3.1 Architecture
|
| 26 |
+
|
| 27 |
+
Our model consists of two modality-specific encoders and a fusion module. The image encoder uses a patch-based embedding followed by Transformer blocks. The text encoder uses token embeddings with positional encoding. The fusion module combines features from both encoders using a cross-attention mechanism.
|
| 28 |
+
|
| 29 |
+
### 3.2 Training Objective
|
| 30 |
+
|
| 31 |
+
We employ a combination of contrastive and supervised objectives. The contrastive term aligns image and text representations in a shared embedding space, while the supervised term operates on task-specific labels.
|
| 32 |
+
|
| 33 |
+
### 3.3 Implementation Details
|
| 34 |
+
|
| 35 |
+
The model is trained with the AdamW optimizer using a cosine learning rate schedule. We apply gradient clipping and dropout regularization. Training runs for up to 30 epochs with early stopping.
|
| 36 |
+
|
| 37 |
+
## 4. Experiments
|
| 38 |
+
|
| 39 |
+
### 4.1 Setup
|
| 40 |
+
|
| 41 |
+
We evaluate on standard multimodal benchmarks. All experiments use a batch size of 32 and train on a single GPU.
|
| 42 |
+
|
| 43 |
+
### 4.2 Main Results
|
| 44 |
+
|
| 45 |
+
| Method | Accuracy | Parameters |
|
| 46 |
+
|--------|----------|------------|
|
| 47 |
+
| Baseline | 78.2% | 12M |
|
| 48 |
+
| Ours (small) | 82.5% | 8M |
|
| 49 |
+
| Ours (base) | 85.3% | 15M |
|
| 50 |
+
|
| 51 |
+
Our approach achieves better accuracy with fewer parameters than the baseline, demonstrating the effectiveness of our design choices.
|
| 52 |
+
|
| 53 |
+
### 4.3 Ablation Study
|
| 54 |
+
|
| 55 |
+
We ablate key components of our model to understand their individual contributions. Removing the fusion module drops accuracy by 4.1 points, confirming that cross-modal attention is important.
|
| 56 |
+
|
| 57 |
+
## 5. Conclusion
|
| 58 |
+
|
| 59 |
+
We presented an approach to self-supervised multimodal learning that achieves competitive results with a compact architecture. Our experiments highlight the importance of efficient fusion strategies for small-scale multimodal models. Future work could explore extending our approach to additional modalities and larger-scale pretraining.
