Abstract: Embodiments relate to generating time-series energy usage forecast predictions for energy consuming entities. Machine learning model(s) can be trained to forecast energy usage for different energy consuming entities. For example, a local coffee shop location and a large grocery store location are both considered retail locations, however their energy usage over days or weeks may differ significantly. Embodiments organize energy consuming entities into different entity segments and store trained machine learning models that forecast energy usage for each of these individual entity segments. For example, a given machine learning model that corresponds to a given entity segment can be trained using energy usage data for entities that match the given entity segment. A forecast manager can generate a forecast prediction for an energy consuming entity by matching the entity to a given entity segment and generating the forecast prediction using the entity segment's trained machine learning model.

The method includes: acquiring an end-of-charge voltage, an end-of-discharge voltage and a rated capacity based on a basic parameter table for a lithium battery, then setting a safety end-of-charge voltage and a safety end-of-discharge voltage to obtain an initial safety discharge capacity, and finally setting a preset discharge capacity of the battery; using an Ampere-hour integration method to estimate a discharged power, taking the preset discharge capacity as a discharge standard, and stopping discharge when the discharged power reaches the preset discharge capacity; and the safety discharge capacity being gradually less than the preset discharge capacity within a battery life cycle, and the battery stopping discharge when the voltage reaches the safety end-of-discharge voltage.

Abstract: Embodiments implement non-intrusive load monitoring using a novel learning scheme. A trained machine learning model configured to disaggregate device energy usage from household energy usage can be stored, where the machine learning model is trained to predict energy usage for a target device from household energy usage. Household energy usage over a period of time can be received, where the household energy usage includes energy consumed by the target device and energy consumed by a plurality of other devices. Using the trained machine learning model, energy usage for the target device over the period of time can be predicted based on the received household energy usage.

Abstract: Techniques for detecting and remediating anomalous intervals in time-series data of a monitored device are disclosed. A system trains a machine learning model on a combination of real data obtained from a monitoring device and false data generated by adding noise to the real data. The model predicts operating values for the device at individual intervals of a time-series data set. The system identifies anomalies in the time-series data based on differences between the predicted values and the real values. If the difference between a predicted value generate by the machine learning model and the real value exceeds a threshold, the system identifies a particular data point, such as a meter reading, as anomalous. The system ranks anomalies to perform remediation operations based on the ranking.

Using the trained machine learning model, multiple discovery predictions for the received instances of source location energy usage can be generated, the discovery predictions comprising a prediction about a presence of target device energy usage within the instances of source location energy usage. And based on the multiple discovery predictions, an overall prediction about a presence of target device energy usage within the given source location's energy usage over the period of time can be generated.

Abstract: A container kernel upgrade based on a programmable container kernel, includes, in response to receiving a container kernel upgrade request, freezing an application container in which a to-be-upgraded first container kernel is located. Current container status data of an application container including first container kernel status data and application status data is stored. The application container is restarted by using a second container kernel used for upgrading a container kernel, where restarted container status data of the restarted application container includes second container kernel status data corresponding to the second container kernel when the application container is restarted. Using the stored current container status data, a corresponding data field is updated in a data structure of the restarted container status data.

Abstract: Embodiments select households using machine learning predictions. One or more trained machine learning models can be stored. For example, at least one machine learning model can be trained to predict household income using time-series energy usage data. Input data including time-series energy usage data for a plurality of households can be received. Using the trained machine learning models, a household income is predicted per household. A subset of the households with a predicted household income that meets one or more campaign criteria can be selected. For example, the selected subset of the households can be targeted by an energy campaign that corresponds to the campaign criteria, and the energy campaign comprise one or more actions to alter energy usage for the targeted households.
