摘要： A machine learning model is trained. A feature importance metric is determined for each machine learning feature of a plurality of machine learning features of the machine learning model. Based on the feature importance metrics, one or more machine learning features of the plurality of machine learning features of the machine learning model are managed.

摘要： The disclosure is directed to receiving a digitized content item that is indicated to be shared with users (e.g., all, some, or one) of a social networking system; selecting, based on one or more characteristics of the digitized content item, a second server computing device at which to further compute or store the digitized content item; and transmitting, to the second computing device, the digitized content item for storage at the second computing device. At least one of the characteristics can be a classification of a user who transmitted the digitized content item via the data communications network. By selecting second server computing devices based on characteristics, data communications network performance can be improved.

摘要： In one embodiment, a method includes establishing access to first and second different computing systems. A machine learning model is assigned for training to the first computing system, and the first computing system creates a check-point during training in response to a first predefined triggering event. The check-point may be a record of an execution state in the training of the machine learning model by the first computing system. In response to a second predefined triggering event, the training of the machine learning model on the first computing system is halted, and in response to a third predefined triggering event, the training of the machine learning model is transferred to the second computing system, which continues training the machine learning model starting from the execution state recorded by the check-point.

摘要： A system and method for multi-channel communication with dual in-line memory modules (“DIMMs”) is disclosed. The system retrieves information characterizing a plurality of memory channels, each of each is configurable to facilitate data communication between a DIMM and a memory controller with associated memory channel interfaces. Based on the retrieved information, one of the memory channels is designated as the active memory channel, granting the designated memory channel the ability to issue memory requests or transactions to the DIMM. On a periodic or as-needed basis (e.g., when the active memory channel is stalled or nearly stalled), the system determines whether to designate a different of the memory channels as the active memory channel, thereby enabling the newly-designated active memory channel the ability to issue memory requests or transactions to the DIMM. In some embodiments, only one of the memory channels is active at a time for communication with each DIMM.

摘要： It is determined that a selected server among a pool of servers is eligible to be utilized for machine learning training. At least the selected server is utilized to train at least a portion of a machine learning model. It is determined that the selected server among the pool of servers is no longer eligible to be utilized for machine learning training. A training state of the machine learning model is saved. The selected server is returned for other use in the pool of servers.
