A feature set is a crucial object in Continual that comprises a collection of features, metadata, and data associated with them. It is essential for conducting data analysis, as it contains an index and can also have a time index indicating the sequence of the data. If a feature set has a time index, it is known as temporal, and each row is identified uniquely by the combination of the index and time index.
For instance, a feature set named “customer_account_info” might have demographic information about clients, and a column known as “customer_id” would uniquely identify each customer. While another feature set named “customer_transactions” will have information about all transactions with the customers. This feature set will have “customer_id” and “ts” (time index) columns to identify each transaction uniquely.

- The combination of the index and time index uniquely identifies each row in a temporal feature set.
Frequently Asked Questions (FAQs)
What is the significance of a feature set in data analysis?
A feature set is crucial in data analysis as it comprises all the relevant data required to perform the required analysis.
What is the difference between a temporal and nontemporal feature set?
A temporal feature set has a time index indicating the sequence of data, and each row in a temporal feature set is identified uniquely by the combination of the index and time index. In contrast, a nontemporal feature set does not have a time index and is identified uniquely by the index only.
A feature set is a crucial object in the Continual platform, as it contains relevant data required for conducting data analysis. It is identified uniquely by an index and can optionally have a time index indicating the sequence of data. Understanding feature sets’ importance is vital for performing successful data analysis within the Continual platform.
