To enable computers to understand, interpret, and generate human language in a valuable manner.

What is the key purpose of Ensemble Methods in machine learning?

To reduce both bias and variance of a learning model.

What is the main objective of Anomaly Detection in unsupervised learning?

To identify unusual data points or patterns that deviate from normal behavior within a dataset.

What is the purpose of the 'Validation' dataset?

To measure performance of known data against algorithms

Which process involves filtering data from unwanted entries such as irrelevant, duplicated, and missing data?

Data Cleaning

What is the primary objective of supervised learning?

Make predictions based on input and output data

Which machine learning method is used to compress data using fewer numbers?
