What is unsupervised learning?

Back

Unsupervised learning is a type of machine learning where the model learns patterns from data without labeled responses.

Front

True or False: Unsupervised learning is more about predicting variable values than relationships between variables.

Back

False

Front

What does the Curse of Dimensionality refer to?

Back

It refers to the challenges that arise when working with high-dimensional datasets, such as overfitting and loss of information.

Front

What is a kernel in convolutional neural networks used for?

Back

A kernel is used for multiplying and aggregating small chunks of an image.

Front

What is a common loss function used in linear regression?

Back

Mean absolute error.

Front

What is anomaly detection?

Back

Anomaly detection is identifying unusual patterns or outliers in data.

Front

Give an example of anomaly detection.

Back

Identifying unusual purchases on a credit card.

Front

What is overfitting in machine learning?

Back

Overfitting occurs when a model learns the training data too well, including noise, and performs poorly on new data.

Front

What is underfitting in machine learning?

Back

Underfitting happens when a model is too simple to capture the underlying patterns in the data.

Front

What is a dataset?

Back

A dataset is a collection of data points used for analysis or training a model.
