7.8 Evaluation Limits

Similarly to the rest of resources in BigML, evaluations have some limits in the number of classes, terms, and items allowed per field:

• Classes: a maximum number of 1,000 distinct classes per field is allowed.

• Terms: BigML can handle up to 1,000 tokens in total. In case multiple text fields are defined, then the token limit per field is evenly divided by the number of text fields, e.g., a dataset with two text fields would result in 500 terms per text field. BigML selects those terms with most significant frequency, discarding both those that appear either too often or too infrequently. Moreover, a maximum of 256 characters are allowed.

• Items: a maximum number of 10,000 distinct items per field is allowed.
