    Abstract: The subject technology receives information associated with a machine learning model. The subject technology determines a set of metrics based at least in part on the information associated with the machine learning model, where the set of metrics corresponds to respective indicators of performance of the machine learning model based on input data from a data set, the set of metrics further including a number of errors produced by the machine learning model when applied to the input data from the data set. Further, the subject technology displays a user interface based at least in part on the set of metrics, where the user interface includes a set of graphical elements, and the set of graphical elements further includes representations of the set of metrics, and representations of the input data from the data set utilized by the machine learning model.

    Abstract: The subject technology receives, in an application on an electronic device, a message, the message being associated with a user and including information in a header portion of the message. The subject technology determines, on the electronic device, a current state of messaging activity of the user based at least in part on a log of previous events associated with the user, where the log of previous events includes information that has been hashed using a cryptographic hash function. The subject technology determines, on the electronic device using a set of rules provided by a machine learning model, that the user is likely to view the message based on the current state of the messaging activity of the user. The subject technology sets, on the electronic device, an indication that the message is important based on the determining.

    Abstract: The subject technology provides for generating a set of nodes representing a tree structure, each node comprising a feature index, a flag field indicating branch directions, an execution index storing locations related to the branch directions, and a feature value for comparing with the value stored in the input feature vector. The subject technology generates evaluation data, the evaluation data comprising a first array containing index values, and a second array containing evaluation values respectively corresponding to the index values, the evaluation data representing values of leaf nodes from the set of nodes. Further, the subject technology stores the set of nodes and the evaluation data as a contiguous block of data, where the set of nodes includes a first node and a second node, the second node corresponding to a likely execution path from the first node being physically stored adjacent to the first node.
