How do I tune the K value in my machine learning model?
Tuning the K value involves selecting the optimal number of neighbors for algorithms like K-NN. You can use techniques like cross-validation.
What is cross-validation and how does it help in tuning?
Cross-validation is a technique to assess how the results of a statistical analysis will generalize to an independent dataset. It helps in tuning by providing a more reliable estimate of model performance.
Are there any specific methods for choosing the K value?
Yes, methods like the elbow method, grid search, and random search can help you find the best K value.
What is the elbow method?
The elbow method involves plotting the error rate against different K values and looking for a point where the rate of decrease sharply changes, resembling an 'elbow'.
