Abstract: In various examples, the present disclosure describes methods and systems for generating hand state predictions. A hand state prediction system includes a machine learning-based model, such as a neural network model, that is trained to convert inertial motion measurements and surface contact data into predictions of a corresponding hand gesture or gripping posture. For each window of data sampled, motion data and contact data are obtained, processed and fused to generate a fused prediction. The hand state prediction system can operate in continuous mode to automatically detect a start and an end of a hand action, or a user can designate a start and an end of a hand action. A hand state prediction is generated by a multimodal classifier by processing the fused prediction. Instructions represented by a hand action can be acted upon through a command action performed by a computing device or a computer application.

Abstract: In various embodiments, a hindsight application computes a hindsight metric value for evaluation of a video rate selection algorithm. The hindsight application determines a first encoding option associated with a source chunk of a media title based on a network throughput trace and a buffer trellis. The hindsight application determines that the first encoding option is associated with a buffered duration range. The buffered duration range is also associated with a second encoding option that is stored in the buffer trellis. After determining that the first encoding option is associated with a higher visual quality than the second encoding option, the hindsight application stores the first encoding option instead of the second encoding option in the buffer trellis to generate a modified buffer trellis. Finally, the hindsight application computes a hindsight metric value associated with a sequence of encoded chunks of the media title based on the modified buffer trellis.

Abstract: One or more computer processors identify a string within source code associated with a program integrated interface (PII). The one or more computer processors compare the identified string to a string entry comprised in a PII dictionary. The one or more computer processors, responsive to a match between the identified string and the string entry in the PII dictionary, classify the identified string as translatable or non-translatable based on a classification associated with the string entry. The one or more computer processors, responsive to a non-match between the identified string and the string entry in the PII dictionary, classify the identified string as translatable or non-translatable utilizing a hyperplane model trained with a margin (C) derived from unlimited search. The one or more computer processors, responsive to a classified translatable string, translate the classified translatable string.
