 - Initialize weights using [Xavier Initialization](https://d2l.ai/chapter_multilayer-perceptrons/numerical-stability-and-init.html#xavier-initialization) to prevent vanishing/exploding gradients instead of initializing them randomly.
 - Replace LSTM with a [Bidirectional LSTM](https://en.wikipedia.org/wiki/Bidirectional_recurrent_neural_networks) to use both left and right context for predicting sentiment.

 Building a neural network from scratch with NumPy is a great way to learn more about NumPy and about deep learning. However, for real-world applications you should use specialized frameworks — such as PyTorch, JAX or TensorFlow — that provide NumPy-like APIs, have built-in automatic differentiation and GPU support, and are designed for high-performance numerical computing and machine learning.
