public sealed class FeatureMap : IMessage<FeatureMap>, IEquatable<FeatureMap>, IDeepCloneable<FeatureMap>, IBufferMessage, IMessage
Reference documentation and code samples for the Recommendations AI v1beta1 API class FeatureMap.
FeatureMap represents extra features that customers want to include in the
recommendation model for catalogs/user events as categorical/numerical
features.
public MapField<string, FeatureMap.Types.StringList> CategoricalFeatures { get; }
Categorical features that can take on one of a limited number of possible
values. Some examples would be the brand/maker of a product, or country of
a customer.
Feature names and values must be UTF-8 encoded strings.
For example: { "colors": {"value": ["yellow", "green"]},
"sizes": {"value":["S", "M"]}
