Dataset

How it is used

Countable: one dataset, two datasets. Engineers collect, clean, split, label and version datasets, and well-known public ones are referred to by name. In ML it is written as one word; 'data set' also appears in statistics.

Example sentences

1. We split the dataset into training, validation and test sets.

2. Is this dataset licensed for commercial use?

Related terms

• training dataThe examples a model learns from during training. Their quality, size and variety largely decide how well the model works on new data.
• test setA part of the data kept aside and used only at the end, to measure how well a finished model works on examples it has never seen.
• validation setA part of the data kept out of training and used during development to compare models, tune settings and decide when to stop training.
• labelThe correct answer attached to a training example, such as 'spam' for an email or 'cat' for a photo, which a supervised model learns to predict.
• annotationThe work of adding labels or notes to raw data, such as drawing boxes around objects in images or marking the topic of each sentence, so that it can be used for training or evaluation.
