  • Publication number: 20240046115
    Abstract: A prediction system of an online system deploys one or more machine-learned architectures to generate predictions. In one embodiment, the machine-learned architecture is a stacked ensemble model. The stacked ensemble model includes a plurality of base models, where a base model is coupled to receive input data and generate a base prediction for the input data. The stacked ensemble model includes a meta model that combines the base predictions to generate a meta prediction for the input data. The prediction system also generates a reliability measure that takes advantage of the base predictions to evaluate the reliability of the meta prediction. In this manner, while the quality of individual predictions may differ from one another depending on the values of the input data, the prediction system can dynamically generate the reliability measure to account for this variation.

  • Publication number: 20220150143
    Abstract: A processing system including at least one processor may generate a binary traffic vector from a traffic flow in a communication network. The binary traffic vector may comprise a plurality of elements, each associated with a respective time period and comprising one of: a first value or a second value. For each time period the traffic flow comprises a transfer of a data unit, a corresponding element comprises the first value, and for time period the traffic flow does not comprise a transfer of a data unit, a corresponding element comprises the second value. The processing system may then apply a traffic flow record comprising the binary traffic vector as an input to a deep learning classifier trained to classify traffic flow records into traffic categories, and determine a traffic category from an output of the deep learning classifier in accordance with the traffic flow record as the input.
