# ResNet50 + LoRA for Bird Classification (CUB-200-2011)

This repository contains LoRA (Low-Rank Adaptation) adapters fine-tuned on the CUB-200-2011 dataset for bird image classification. These adapters are designed to be applied to a standard `torchvision.models.resnet50` base model.

## Model Details

*   **Base Model:** `torchvision.models.resnet50` (pre-trained on ImageNet).
*   **Fine-tuning Method:** Low-Rank Adaptation (LoRA) using the `peft` library.
*   **Dataset:** [Caltech-UCSD Birds-200-2011 (CUB-200-2011)](https://data.caltech.edu/records/65de6-vp158)
*   **Number of Classes:** 200 bird species.
*   **LoRA Configuration:**
    *   Rank (`r`): 8 (as used in training, please verify/update)
    *   Alpha (`lora_alpha`): 16 (as used in training, please verify/update)
    *   Target Modules: ["fc", "conv1", "layer4.0.conv1"] (Please list the actual modules targeted during training)
    *   Dropout: 0.05
    *   Bias: "none"

## How to Use

First, make sure you have `torch`, `torchvision`, and `peft` installed:
```bash
pip install torch torchvision peft Pillow
