Machine learning may be personalized to individual users of computing devices, and can be used to increase machine learning prediction accuracy and speed, and/or reduce memory footprint. Personalizing machine learning can include hosting, by a computing device, a consensus machine learning model and collecting information, locally by the computing device, associated with an application executed by the client device. Personalizing machine learning can also include modifying the consensus machine learning model accessible by the application based, at least in part, on the information collected locally by the client device. Modifying the consensus machine learning model can generate a personalized machine learning model. Personalizing machine learning can also include transmitting the personalized machine learning model to a server that updates the consensus machine learning model.

The method of claim 8, further comprising: transmitting the updated personalized machine learning model to the server; and receiving an updated global machine learning model from the server, wherein the updated global machine learning model is based, at least in part, on i) the updated personalized machine learning model transmitted to the server and ii) an aggregation of a plurality of other updated personalized machine learning models transmitted from at least a portion of the plurality of other client devices to the server. 10. A method comprising: hosting, by a server, a global machine learning model; receiving, from a plurality of client devices, personalized machine learning models, wherein the personalized machine learning models are based, at least in part, on information collected locally by each of the plurality of client devices; modifying the global machine learning model based, at least in part, on the personalized machine learning models received from the plurality of client devices, wherein modifying the global machine learning model generates a modified global machine learning model; and transmitting the modified global machine learning model to at least a portion of the plurality of client devices. 11. The method of claim 10, wherein modifying the global machine learning model is further based, at least in part, on a hinge loss function including vectors representing (i) an aggregation of the information collected locally by the plurality of client devices, (ii) target labels of the modified global machine learning model, (iii) the modified global machine learning model, and the transpose of the vector representing the modified global machine learning model. 12. The method of claim 11, wherein modifying the global machine learning model is further based, at least in part, on a minimization operation of a product of the global machine learning model and an estimate of a Lagrange multiplier. 13. The method of claim 10, wherein the personalized machine learning models received by the server include de-identified data representative of the information collected locally by the client devices. 14. The method of claim 13, wherein the de-identified data comprises private information of users of the client devices. 15. The method of claim 10, wherein modifying the global machine learning model and/or transmitting the modified global machine learning model is performed asynchronously with the plurality of the client devices. 16. The method of claim 10, wherein information collected locally by each of the plurality of client devices information comprises one or more of the following: a captured image of a user of the client device, a captured voice sample of the user of the client device, or a received search query from the user of the client device. 17. The method of claim 10, further comprising: further modifying the global machine learning model based, at least in part, on additional information collected locally by at least a portion of the client devices, wherein further modifying the global machine learning model generates an updated global machine learning model; and transmitting the updated global machine learning model to at least another portion of the plurality of the client devices. 18. Computer-readable storage media of a client device storing computer-executable instructions that, when executed by one or more processors of the client device, configure the one or more processors to perform operations comprising: hosting, by the client device, a consensus machine learning model; collecting information, locally by the client device, associated with an application executed by the client device; and modifying the consensus machine learning model accessible by the application based, at least in part, on the information collected locally by the client device, wherein modifying the consensus machine learning model generates a personalized machine learning model; transmitting the personalized machine learning model to a server; and receiving a global machine learning model from the server, wherein the global machine learning model is based, at least in part, on i) the personalized machine learning model transmitted to the server and ii) an aggregation of a plurality of other personalized machine learning models transmitted from a plurality of other client devices to the server. 19.
