A Practical Approach to Timeseries Forecasting Using Python - GRU Models

The video tutorial discusses Gated Recurrent Units (GRUs) and compares them with Long Short-Term Memory (LSTM) networks. GRUs are computationally cheaper and faster but less accurate for longer sequences compared to LSTMs. The tutorial explains the three gates of GRUs: update, reset, and current memory gate, and how they function. It also covers the implementation of GRU and simple RNN layers in Python, highlighting the code similarities with LSTMs. The focus then shifts to LSTM models, discussing issues of underfitting and overfitting, and how to address them.
