Questions & Answers

Q: What is the significance of transfer potential in neural networks?

Transfer potential combines inputs from various nodes, applying weights to learn features and patterns critical for model learning and predictions.

Q: How does feature scaling impact data processing in neural networks?

Feature scaling normalizes data, ensuring consistent ranges for inputs to stabilize network training and prevent biases from dominating model outputs.

Q: Why is softmax activation used in output layers for classification tasks?

Softmax normalizes outputs to probability distributions, ensuring predictions sum to 1 and allowing the model to make confident class predictions.

Q: How does K-fold cross-validation help in training and evaluating neural networks?

K-fold partitioning ensures robust model evaluation by dividing data into multiple subsets for iterative training and validation, reducing bias and variance errors.
