What is the primary difference between the 'Validation' and 'Test' datasets?

Validation dataset is used to measure model performance, while the Test dataset contains unknown data for evaluating the model's performance.

What is the main objective of Dimensionality Reduction in machine learning?

To remove irrelevant and redundant information from the data.

In machine learning, what does Transfer Learning involve?

Re-using a pre-trained neural network and adapting it to a similar task.

What is the primary function of Natural Language Processing (NLP) in machine learning?

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?

Dimensionality reduction

What is a key requirement for deep learning to capture non-linear patterns?
