3D human body pose estimation using a model trained from unlabeled multi-view data
Learning to estimate a 3D body pose, and likewise the pose of any type of object, from a single 2D image is of great interest for many practical graphics applications and generally relies on neural networks that have been trained with sample data which annotates (labels) each sample 2D image with a known 3D pose. Requiring this labeled training data however has various drawbacks, including for example that traditionally used training data sets lack diversity and therefore limit the extent to which neural networks are able to estimate 3D pose. Expanding these training data sets is also difficult since it requires manually provided annotations for 2D images, which is time consuming and prone to errors. The present disclosure overcomes these and other limitations of existing techniques by providing a model that is trained from unlabeled multi-view data for use in 3D pose estimation. |

Method and system for summarizing user activities of tasks into a single activity score using machine learning to predict probabilities of completeness of the tasks
Activity data of a set of tasks as a training set is obtained from a list of communication platforms associated with the tasks. For each of the tasks in the training set, a set of activity metrics is compiled according to a set of predetermined activity categories based on the activity data of each task. The activity metrics of all of the tasks in the training set are aggregated based on the activity categories to generate a data matrix. A principal component analysis is performed on the metrics of its covariance matrix to derive an activity dimension vector, where the activity dimension vector represents a distribution pattern of the activity metrics of the tasks. The activity dimension vector can be utilized to determine an activity score of a particular task, where the activity score of a task can be utilized to estimate a probability of completeness of the task. |

Dynamic modification of interruptibility settings for network-accessible resources
Methods and apparatus for dynamic modification of interruptibility settings of network-accessible resources are disclosed. A system includes a resource manager and a plurality of resource instances, each of which has an interruptibility setting. In response to an instance acquisition request, the resource manager allocates an instance with a first interruptibility setting, allowing the resource manager to revoke the client's access to the instance without a notification. In response to an approval of an interruptibility upgrade request, the resource manager modifies the interruptibility setting to a second setting that allows the client to retain access to the instance for at least a specified time. Respective billing amounts for the client's use of the instance are determined for each of the interruptibility settings used. |
