Poultry-Meat-Freshness-Classification-with-Transfer-Learning-using-ResNet-Architecture

The utilization of the ResNet architecture and Transfer Learning methods to classify Poultry Meat Freshness images into two categories, namely Fresh and Rotten.

About The Project

• In this repository, we leverage the power of the Residual Networks (ResNet) architecture and Transfer Learning techniques to accurately classify the freshness of poultry meat. By utilizing pre-trained ResNet weights, sourced from ImageNet, our model gains the ability to make fine-grained distinctions in poultry meat freshness.
• The pre-trained weights from the ImageNet dataset, which includes a wide range of object categories, are used to enhance the model's ability to recognize and classify fresh and rotten poultry meat images.
• This repository provides a comprehensive implementation of the classification process and serves as a valuable resource for exploring the world of Transfer Learning with ResNet architecture.
• Key Features
  • Implementation of Transfer Learning with ResNet architecture.
  • Classification of poultry meat freshness into different categories.
  • Utilizes a pre-trained model to enhance classification accuracy.
  • Implement hyperparameter tuning using Grid Search to obtain the best model/ set of parameters.
  • Helps in maintaining food safety and quality standards.

  • Batch = 10 (100 steps per epoch, because the number of training data is 1000)
  • Optimizer = Mini Batch Gradient Descent
  • Loss/ Cost Function = Binary Cross Entropy
  • Metrics = Accuracy
• Hyperparameters (Fine Tuned with Grid Search):
  • Epoch:
    • 100
    • 200
  • Learning rate:
    • 0.0001
    • 0.0003
    • 0.0007
  • Momentum:
    • 0.0
    • 0.9
