Frequently Asked Questions (FAQs):

1. What is the difference between supervised and unsupervised learning? Answer: Supervised learning involves training a model on labeled data, while unsupervised learning works with unlabeled data, identifying patterns and structures on its own.
2. How does overfitting affect machine learning models? Answer: Overfitting occurs when a model learns the training data too well, including noise and outliers, leading to poor performance on new, unseen data.
3. What is the importance of feature selection in machine learning? Answer: Feature selection helps in improving model performance by choosing only the most relevant input variables, reducing model complexity, and enhancing generalization.
4. Can you explain the concept of a neural network? Answer: A neural network is a series of algorithms that mimic the human brain’s operation, designed to recognize patterns and interpret sensory data through machine perception, labeling, and clustering.
5. What are the advantages of using Random Forest over Decision Trees? Answer: Random Forests reduce the risk of overfitting by averaging multiple decision trees, leading to improved accuracy and robustness.
6. How is Principal Component Analysis (PCA) used in machine learning? Answer: PCA is used for dimensionality reduction, simplifying the complexity in high-dimensional data while retaining trends and patterns.
7. What is Q-learning in reinforcement learning? Answer: Q-learning is a model-free reinforcement learning algorithm that seeks to learn the value of an action in a particular state, guiding the agent to the optimal action.
8. Can machine learning be applied in healthcare? Answer: Yes, machine learning is increasingly used in healthcare for applications like disease prediction, personalized treatment, and medical image analysis.
9. What are GANs and how are they used? Answer: Generative Adversarial Networks (GANs) are a class of AI algorithms used in unsupervised machine learning, implemented by a system of two neural networks contesting with each other.
10. What does the term ‘bias’ mean in machine learning? Answer: In machine learning, bias is the tendency of an algorithm to consistently learn the wrong thing by not taking into account all aspects of the applied data.
