Abstract: The present disclosure provides a method and system for efficiently and securely managing human motion data. In one aspect, a human-motion-data-managing system first receives a sequence of video images including a first person. Next, for each image in the sequence of video images, the human-motion-data-managing system detects the first person in the video image; and subsequently extracts a skeleton figure of the detected first person from the image, wherein the skeleton figure is composed of a set of human keypoints. Next, human-motion-data-managing system combines a sequence of extracted skeleton figures of the detected first person from the sequence of video images to form a skeleton sequence of the detected first person which depicts a continuous motion of the first person. The human-motion-data-managing system subsequently transmits the skeleton sequence to a server in place of the actual images of the first person to preserve the privacy of the first person.

Abstract: Disclosed techniques and solutions can provide improved snapshot replication. Typically, an initial replica obtained using snapshot replication is periodically updated. However, the update process can unnecessarily consume computing resources if data in a source data object has not changed with respect to data in a replica data object. Disclosed techniques check to determine whether a snapshot replica is out of date before obtaining a new snapshot. The checks can be performed on manual request or on the occurrence of triggers, such as receiving a query that accesses the replica data object or according to a schedule. Information for current and prior versions of the remote data object can be compared to determine whether a replica is out of date, such as digest values of contents of the remote data object or timestamps associated with the remote data object.

Abstract: Methods and systems are described for providing hierarchical demand forecasting for state space reduction. Using a hierarchical architecture, a base model may be trained to capture a range of shared structure in a first data set that can be used to draw inferences on using smaller sets of data representative of the “whole picture.” For example, training data may be sampled and prepared and used to train a base model in a first stage. In a next stage, one or more downstream models may be trained on the structure and samples of uncensored demand generated by the base model to produce forecasts for items and locations, including items and locations for which there may be little or no historical data. The downstream models that would otherwise require a large amount of data for training can be generated on demand using less training data, training time, computing processing, and memory.
