Image Captioning using Transformers

This project implements an image captioning model utilizing CNN and Transformer architectures. The model architecture is as follows:

Architecture

1. CNN as Feature Extractor:

   • We use EfficientNetB0 as the Convolutional Neural Network (CNN) to extract features from the images.

2. Transformer Encoder:

   • The extracted features from the CNN are passed to the encoder, which consists of multiple Transformer layers.
   • These layers process the features and prepare them for decoding.

3. Transformer Decoder:

   • The decoder, which also comprises Transformer layers, generates captions for the images based on the features provided by the encoder.

4. Data

   • Each input image is associated with five captions.
   • Data preprocessing and augmentation techniques are applied to improve the model's robustness and performance.

5. Model Training

   • Once the model is trained, the results, metrics, and the trained model itself are logged using MLFlow and DagsHub for efficient tracking and management of model development.
