Abstract: The present application discloses a WebRTC communication method. The method includes acquiring first device information of a calling terminal device and second device information of a called terminal device; determining, based on the first device information and the second device information, whether there is nonessential information with respect to establishing a connection; and in response to determining that there is the nonessential information, establishing a WebRTC connection between the calling terminal device and the called terminal device with the nonessential information being excluded and implementing communications between the calling terminal device and the called terminal device. According to the technical solution disclosed in the present application, a network bandwidth and performance consumption of a signaling server can be reduced by over 30%, without affecting a success rate of establishing the WebRTC connection between the two terminal devices.

Abstract: Technologies described herein relate to training and compressing a computer-implemented model. To that end, an untrained computer-implemented model is obtained, where the untrained computer-implemented model is to be trained and compressed. The untrained computer-implemented model includes an operator that comprises a structure. Further, training data is obtained, where the training data is to be employed to train the computer-implemented model. Upon receipt of a request from a user, the untrained computer-implemented model is trained and compressed based upon the training data. The untrained computer-implemented model is trained and compressed without further input from the user, such that a trained and compressed computer-implemented model is generated. The trained and compressed model does not include the structure.

Abstract: A computer-implemented method includes identifying offline evaluation metrics that indicate, for a given feedback loop in a recommendation system, various feedback loop characteristics that are detrimental to the feedback loop. The method also includes generating a predictive machine learning (ML) model that correlates the identified offline evaluation metrics with indications of those feedback loop characteristics that are detrimental to the feedback loop. The method further includes instantiating the predictive ML model to predict, using the correlated offline evaluation metrics and the detrimental feedback loop characteristics, how the feedback loop will be negatively affected over time, and providing, to at least one entity, an indication of how the feedback loop will be negatively affected over time due to the detrimental feedback loop characteristics. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: Embodiments relate to automatic determination of a directed spend program eligibility for items offered by retailers associated with an online system. The online system provides inputs into a computer model, where the inputs include information about at least one property for each candidate item in a set of candidate items and at least one requirement for a directed spend program. The online system applies the computer model to generate, based on the inputs, an output that comprises an indication of an eligibility for each candidate item in the set for the at least one directed spend program. The online system sends a message causing a device of a user of the online system to display a user interface including an option for the user to add into a cart at least one of the candidate items determined to be eligible for the directed spend program.

Abstract: Techniques of integrating lateral HBT devices into a silicon on insulator (SOI) CMOS process. Similar approaches could also be applied to Fin Field-Effect Transistors (FinFETs). A first technique makes use of a CMOS replacement gate process that is typically associated with a partially depleted SOI (PDSOI) or fully depleted SOI (FDSOI) process. A second technique is independent of the CMOS process. Both techniques can accommodate silicon germanium (SiGe) and/or III-V materials, include a self-aligned base contact, and can be used to construct both NPN and PNP transistors with varied peak fT and breakdown voltages.
