Fun with Machine Learning

What is Machine Learning?

• Machine Learning is a programming language for data analysis.

• Machine Learning is a type of computer hardware.

• Machine Learning is a method for manual data entry.

• Machine Learning is a field of artificial intelligence that focuses on the development of algorithms that allow computers to learn from and make predictions based on data.

What are the two main types of Machine Learning?

• Active Learning and Batch Learning

• Deep Learning and Transfer Learning

• Supervised Learning and Unsupervised Learning

• Reinforcement Learning and Semi-supervised Learning

Can you name a simple algorithm used in Machine Learning?

• Linear Regression

• Support Vector Machine

• Decision Tree

• K-Means Clustering

Why do we need to preprocess data?

• To reduce the size of the dataset for faster processing.

• To eliminate all data points that are not useful for any analysis.

• To create random data for testing purposes.

• We need to preprocess data to ensure its quality and suitability for analysis.

What is one way to evaluate a model's performance?

• Use random guesses

• Evaluate based on model size

• Use performance metrics like accuracy or F1 score.

• Ignore the training data

Can you give an example of where Machine Learning is used?

• Email filtering (spam detection)

• Stock market analysis

• Social media engagement

• Weather forecasting

What does supervised learning mean?

• Supervised learning is a machine learning approach that uses labeled data to train models.

• Supervised learning is a type of reinforcement learning.

• Supervised learning is a method that requires no data for training.

• Unsupervised learning uses labeled data to train models.

What is unsupervised learning?

• A method that requires labeled data for training.

• A technique used only for classification tasks.

• An approach that predicts future outcomes based on past data.

• Unsupervised learning is a machine learning approach that finds patterns in data without labeled outcomes.

What is a common technique for cleaning data?

• Changing data types

• Removing duplicates

• Adding random noise

• Sorting data

How can Machine Learning help in everyday life?

• Machine Learning helps in everyday life by personalizing experiences, automating tasks, and improving decision-making.

• Machine Learning is primarily for gaming and entertainment.

• Machine Learning can only be used in scientific research.

• Machine Learning has no impact on personal finance.
