Abstract: Techniques for detecting label shift and adjusting training data of predictive models in response are provided. In an embodiment, a first machine-learned model is used to generate a predicted label for each of multiple scoring instances. The first machine-learned model is trained using one or more machine learning techniques based on a plurality of training instances, each of which includes an observed label. In response to detecting a shift in observed labels, for each segment of one or more segments in multiple segments, a portion of training data that corresponds to the segment is identified. For each training instance in a subset of the portion of training data, the training instance is adjusted. The adjusted training instance is added to a final set of training data. The machine learning technique(s) are used to train a second machine-learned model based on the final set of training data.

Abstract: Embodiments of the subject matter described herein relate to generating a decision tree based on data pre-statistics. A plurality of data samples for a node of the decision tree are obtained, and the plurality of data samples have corresponding feature values with respect to a first feature. A target range is determined from a plurality of predefined numerical ranges so that the number of feature values falling into the target range is greater than a predetermined threshold number. Then, the remaining of the feature values other than the feature values falling into the target range are assigned to the respective numerical ranges, and the feature values falling into all the numerical ranges are counted based on the assignment of the remaining of the feature values, for allocation of the plurality of data samples to child nodes of the node. Accordingly, the data processing efficiency is substantially improved.

Abstract: Techniques and tools for reducing latency in video encoding and decoding by constraining latency due to reordering of video frames, and by indicating the constraint on frame reordering latency with one or more syntax elements that accompany encoded data for the video frames. For example, a real-time communication tool with a video encoder sets a syntax element that indicates a constraint on frame reordering latency, which is consistent with inter-frame dependencies between multiple frames of a video sequence, then outputs the syntax element. A corresponding real-time communication tool with a video decoder receives the syntax element that indicates the constraint on frame reordering latency, determines the constraint on frame reordering latency based on the syntax element, and uses the constraint on frame reordering latency to determine when a reconstructed frame is ready for output (in terms of output order).

Abstract: Website assets are optimized for vulnerability scanning using node centrality techniques. A digital footprint of network nodes associated with a domain is determined. A similarity metric is defined using a weighted linear combination of features of a node. After determining a similarity metric for pairs of related nodes in the digital footprint of a domain, a set of centroids is determined. The reduced set of centroids is acted upon for vulnerability scanning.

Abstract: A virtual network interface controller (NIC) associated with a virtual machine in a cloud computing network is configured to support one or more network containers that encapsulate networking configuration data and policies that are applicable to a specific discrete computing workload to thereby enable the virtual machine to simultaneously belong to multiple virtual networks using the single NIC. The network containers supported by the NIC can be associated with a single tenant to enable additional flexibility such quickly switching between virtual networks and support pre-provisioning of additional computing resources with associated networking policies for rapid deployment. The network containers can also be respectively associated with different tenants so that the single NIC can support multi-tenant services on the same virtual machine.

Abstract: Architecture that enables the detection of a user by a user device and interaction with content of the user device by the user before the user physically contacts the device. The detection capability can utilize one or more sensors of the device to identify the user and the proximity (distance) of the user to the device. Based on the user identity and the proximity, the device operates/functions in a certain way. Moreover, ongoing interaction can be enabled by recognition of a natural user interface (NUI) gestures, alone or in combination with other recognition techniques (e.g., speech recognition). Device activity can include causing the device to operate in predetermined ways such as power modes, application launching and manipulation to cause control of hardware and other software (local and/or remote) and, obtaining and presenting specific types of content (e.g., advertisements, notifications, messages, reminders, news, incoming communications, etc.).

Abstract: Runtime errors in a source code program are detected in advance of execution by machine learning models. Features representing a context of a runtime error are extracted from source code programs to train a machine learning model, such as a random forest classifier, to predict the likelihood that a code snippet has a particular type of runtime error. The features are extracted from a syntax-type tree representation of each method in a program. A model is generated for distinct runtime errors, such as arithmetic overflow, and conditionally uninitialized variables.

Abstract: Polynucleotide sequencing generates multiple reads of a polynucleotide molecule. Many or all of the reads contain errors. Trace reconstruction takes multiple reads generated by a polynucleotide sequencer and uses those multiple reads to reconstruct accurately the nucleotide sequence of the polynucleotide molecule. Some reads may contain errors that cannot be corrected. Thus, there may be reads that can be used throughout their entire length and other reads that have indeterminant errors which cannot be corrected. Rather than discarding the entire read when an indeterminant error is found, the portion of the read with the error is skipped and the sequence of the read following the error is used to reconstruct the trace. The amount of the read skipped is determined by the location of subsequence after the error that matches a consensus sequence of the other reads. Analysis resumes at a location determined by the location of the match.

Abstract: A method of and system for selecting users for a rollout process of a feature is carried out by receiving an indication of the rollout process for the feature being rolled out, accessing a rollout plan, the rollout plan including a plurality of stages for the rollout process, and selecting users from a user population for each of the plurality of stages of the rollout process. Selecting the users from a user population includes examining a property to determine if a user in the user population is indicated as opted into being a late-stage receiver, and upon determining that the user is opted into being the late-stage receiver, excluding the user from the user population for one or more early stages of the rollout and including the user into the user population in one or more late stages of the rollout process.

Abstract: Disclosed in some examples are improved storage, replication, and distribution of data related to network-based meetings (e.g., media) in hierarchical records. Data for one or more components of the meeting (e.g., media) may be stored in a child record (called a component record). The network-based meeting may be described by a parent record with links to, and in some examples descriptions of, the meeting component records (the child records). The meeting object may point to local, and/or replicated copies of the child records. As noted, the child records may be or include media objects and, in some examples, the child records may be replicated to one or more locations based upon a demand for the media object. By replicating the media to a location that is close to demand for the media, this provides for more efficient delivery of media of the meeting.

Abstract: A method for a touch-sensitive display device comprises detecting a position of a stylus touch input relative to a plurality of touch-sensing electrodes, the stylus touch input corresponding to proximity of an active stylus to a display surface. A position of a human hand touch input is detected, corresponding to proximity of a human hand to the display surface. Each of the plurality of touch-sensing electrodes are driven with a first drive signal to communicate data to the active stylus. An electrical grounding condition is detected that interferes with reception of the first drive signal by the active stylus. A hand-proximity-subset of the plurality of touch-sensing electrodes within a threshold distance of the position of the human hand touch input are driven with a second drive signal, different from the first drive signal.
