Kaustubh Kulkarnikaustubhk.hashnode.dev·Sep 23, 2024Bias-Variance Trade-offIn machine learning, the bias-variance trade-off is a fundamental concept used to evaluate the performance of a model. It helps explain the sources of error in predictions. The total error (expected loss) of a model can be decomposed into three compo...Introduction to Machine Learningweek1

Kaustubh Kulkarnikaustubhk.hashnode.dev·Sep 20, 2024Bias in k-NN classifierIn the case of K-nearest neighbors (KNN) classifiers, the bias typically increases as the value of K increases. Here's why: When K is small (e.g., K=1), the model tends to overfit the training data, as it is highly sensitive to noise and anomalies. ...Introduction to Machine Learningweek1
Kaustubh Kulkarnikaustubhk.hashnode.dev·Sep 18, 2024Policy in Reinforcement LearningIn reinforcement learning, a policy is a function or strategy that determines the action an agent should take given a particular state. It essentially maps states to actions, guiding the agent’s behaviour in the environment. The policy can be determi...Introduction to Machine Learningweek1
