Model Description

Fine-tuned Qwen2-VL-2B-Instruct model for image aesthetic assessment using the RvTC (Regression via Transformer-Based Classification) framework. This checkpoint uses image-only training without textual context.

Base Model

• Architecture: Qwen2-VL-2B-Instruct
• Source: Qwen/Qwen2-VL-2B-Instruct

Training Configuration

• Dataset: AVA (Aesthetic Visual Analysis)
• Training Mode: Image-only (no textual prompts)
• Epochs: 2
• Learning Rate: 1e-5
• Batch Size: 128 (training)
• Optimizer: AdamW with cosine scheduler
• Warmup Ratio: 0.03

Binning Configuration

• Number of Bins: 51
• Value Range: [1.81, 8.60] (range of train set)
• Method: Uniform binning for regression via classification

Performance

Evaluated on AVA test set (19,930 samples):

• Pearson Correlation (PLCC): 0.841
• Spearman Correlation (SRCC): 0.843
