santiment analysis with transformer

implement a Transformer model from scratch using TensorFlow and train it to perform sentiment analysis on a given dataset. Task Requirements:

Build the Transformer architecture from scratch (do not use prebuilt Transformer models).

Implement core components manually, including:

  * Multi-Head Self-Attention

  * Positional Encoding

  * Feedforward Neural Network

  * Layer Normalization and Residual Connections

Use TensorFlow/Keras only 

Train your model on a sentiment analysis dataset (e.g., IMDB or similar).
