❓ Frequently Asked Questions
What is machine learning?
A field of AI where computers learn from data to perform tasks without explicit programming, by identifying patterns and making predictions.
What is supervised learning?
A learning approach using labeled data to teach a model to map inputs to outputs, enabling predictions on new data.
What is unsupervised learning?
A learning approach that finds patterns or structure in unlabeled data, such as clustering or dimensionality reduction.
What is data preprocessing?
Cleaning and transforming raw data before training, including handling missing values, scaling, and encoding categorical features.
What are model training and validation?
Training fits the model to data; validation assesses its performance on unseen data to gauge accuracy and generalization.
