❓ Frequently Asked Questions
AI is the broader concept of machines performing tasks that typically require human intelligence, while machine learning is a subset of AI that focuses on learning from data.
Neural networks learn through backpropagation, where errors are propagated backward through the network to adjust weights and biases, gradually improving performance.
Supervised learning uses labeled data to train models, while unsupervised learning finds patterns in data without explicit labels or targets.
Overfitting can be prevented through techniques like regularization, dropout, early stopping, data augmentation, and using validation sets to monitor performance.
Deep learning uses multi-layer neural networks to automatically learn features from data, while traditional ML often requires manual feature engineering.
Activation function choice depends on the problem type: ReLU for hidden layers, sigmoid for binary classification, softmax for multi-class, and tanh for bounded outputs.
Batch size determines how many samples are processed before updating weights, while learning rate controls the step size of weight updates during optimization.
Model performance is evaluated using metrics like accuracy, precision, recall, F1-score, and area under the curve (AUC), depending on the problem type.
Training is the process of learning model parameters from data, while inference is using the trained model to make predictions on new, unseen data.
