How computers recognize patterns and make decisions without being explicitly programmed

Back

machine learning

Answer explanation

Machine learning enables computers to recognize patterns and make decisions by learning from data, rather than being explicitly programmed. This encompasses both supervised and unsupervised learning, but the broader term is machine learning.

Front

The inputs that a model uses to make decisions

Back

features

Answer explanation

In machine learning, 'features' are the inputs used by a model to make decisions. They represent the characteristics or attributes of the data, while 'label' refers to the output or target variable.

Front

the output you are trying to decide or predict with a model

Back

label

Answer explanation

The 'label' refers to the output you aim to predict with a model, distinguishing it from 'features' which are the input variables. Thus, 'label' is the correct choice.

Front

When a human trains a model to learn with examples

Back

supervised learning

Answer explanation

Supervised learning occurs when a model is trained using labeled examples, allowing it to learn patterns and make predictions based on input data. This distinguishes it from unsupervised learning, which uses unlabeled data.

Front

a computer program designed to make a decision

Back

model

Answer explanation

A 'model' in computer programs refers to a system that makes decisions based on input data. It is trained using algorithms to recognize patterns and predict outcomes, making it the correct choice for the question.

Front

Finding patterns in data that doesn't have any labels

Back

unsupervised learning

Answer explanation

Unsupervised learning is the correct choice as it involves finding patterns in data without any labels, unlike supervised learning which requires labeled data.

Front

giving examples to a model so it can learn

Back

training

Answer explanation

The process of giving examples to a model so it can learn is called training. During training, the model uses these examples to adjust its parameters and improve its performance on tasks.

Front

data that can be separated into groups

Back

categorical data

Answer explanation

Categorical data refers to data that can be divided into distinct groups or categories. This makes it the correct choice, as it directly describes data that can be separated into groups, unlike the other options.

Front

predicting a category based on other features

Back

classification

Answer explanation

The process of predicting a category based on other features is known as classification. It involves using input features to assign a label to a data point, making 'classification' the correct choice.

Front

data that can be counted or measured

Back

numerical data

Answer explanation

Numerical data refers to data that can be counted or measured, making it the correct choice. In contrast, categorical data represents categories or groups, while features and classification do not specifically pertain to measurable data.
