Uses

Direct Use

The model can be directly used for analyzing dermatology images, providing insights into potential skin conditions.

Bias, Risks, and Limitations

Skin Tone Bias: The model may have been trained on a dataset that does not adequately represent all skin tones, potentially leading to biased results. Geographic Bias: The model's performance may vary depending on the prevalence of certain conditions in different geographic regions.

How to Get Started with the Model

python

import torch
from transformers import AutoProcessor, PaliGemmaForConditionalGeneration
from PIL import Image

# Load the model and processor
model_id = "brucewayne0459/paligemma_derm"
processor = AutoProcessor.from_pretrained(model_id)
model = PaliGemmaForConditionalGeneration.from_pretrained(model_id, device_map={"": 0})
model.eval()

# Load a sample image and text input
input_text = "Identify the skin condition?"
input_image_path = " Replace with your actual image path"  
input_image = Image.open(input_image_path).convert("RGB")

# Process the input
inputs = processor(text=input_text, images=input_image, return_tensors="pt", padding="longest").to("cuda" if torch.cuda.is_available() else "cpu")

# Set the maximum length for generation
max_new_tokens = 50

# Run inference
with torch.no_grad():
    outputs = model.generate(**inputs, max_new_tokens=max_new_tokens)

# Decode the output
decoded_output = processor.decode(outputs[0], skip_special_tokens=True)
print("Model Output:", decoded_output)

Training Details

Training Data

The model was fine-tuned on a dataset of dermatological images combined with disease names

Training Procedure

The model was fine-tuned using LoRA (Low-Rank Adaptation) for more efficient training. Mixed precision (bfloat16) was used to speed up training and reduce memory usage.

Training Hyperparameters

Training regime: Mixed precision (bfloat16)
Epochs: 10
Learning rate: 2e-5
Batch size: 6
Gradient accumulation steps: 4

Evaluation

Testing Data, Factors & Metrics

Testing Data

The model was evaluated on a separate validation set of dermatological images and Disease Names, distinct from the training data.

Metrics

Validation Loss: The loss was tracked throughout the training process to evaluate model performance.
Accuracy: The primary metric for assessing model predictions.

Results

The model achieved a final validation loss of approximately 0.2214, indicating reasonable performance in predicting skin conditions based on the dataset used.
