Entropy measures randomness in data, while information gain measures the reduction in uncertainty after splitting data.
Entropy is used in decision trees to measure impurity in a dataset before splitting it.
Information gain is used in decision trees to measure the effectiveness of a split in reducing uncertainty.
Entropy ranges from 0 (pure dataset) to 1 (completely impure dataset).
Information gain is calculated as the d...
LSTM for longer sequences, GRU for faster training and less complex models.
Use LSTM for tasks requiring long-term dependencies and memory retention.
Use GRU for faster training and simpler models with fewer parameters.
Consider using LSTM for tasks like language translation or speech recognition.
Consider using GRU for tasks like sentiment analysis or text generation.
