An event driven detection model is disclosed. A model operates at a node to identify relevant video data from video streams generated by cameras. Video data that is not relevant is discarded. An objectness score is generated for the relevant video data. The objectness score and position data from position sensors is used to infer an event. When an event is inferred by the model, a decision may be made and performed.

One method includes receiving, at a central node, a respective gradient from each node of a cluster, and each of the gradients comprises a respective update to a global machine learning model maintained at the central node, aggregating, by the central node, the gradients to obtain an aggregated gradient for the cluster, and the aggregated gradient is part of a list of aggregated gradients, running, by the central node, a robust aggregation operation on the aggregated gradients in the list to obtain an outlier score for the cluster, and when the outlier score equals or exceeds a specified value, or falls within a specified range of values, identifying the cluster as an outlier, and identifying nodes within the cluster as suspicious.

Lightweight attacker identification method for federated learning with secure byzantine-robust aggregation via clustering

One example method includes performing various operations in a federated learning environment that includes nodes configured and operable to communicate with a central server. The operations include gathering aggregate gradient information from clusters that each include a respective group of some of the nodes, examining the respective gradient information for each of the clusters, and identifying outlier clusters based on the respective aggregate gradient information of those clusters, for each of the clusters identified as an outlier cluster, setting all the nodes in those clusters as suspect nodes, and performing a clustering operation that comprises reassigning each of the suspect nodes to one of the clusters, and a decision to reassign any given one of the suspect nodes is based on an amount of information expected to be obtained as a result of that decision.

An edge information handling system (IHS) manager includes a storage for storing a labeled data associated with a use counter; and a vehicle counter; and a processor. The processor is programmed to: update an inference module using the labeled data, determine, after the updating, whether the use counter of the labeled data has exceeded a current use threshold, and in response to the use counter of the labeled data exceeding the current use threshold, initiating replacing of the labeled data with new labeled data from a central IHS. The current use threshold is based on the vehicle counter.

One example method includes identifying features for operational actions that are to be performed at an edge node of an edge computing system. The features include information used by the edge node to execute the operational actions. A first set of the features is received during an input processing stage. The first set of the features are used in the execution of the operational actions. In response to the execution of the operational actions, a second set of the one or more features are obtained, In response to retrieving the first set of the features or in response to obtaining the second set of the features, a local map is updated to include the features. The local map includes a subset of a global map, where the local map and the global map represent a shared representation of a map structure.

Peer-based positioning of nodes in an environment is disclosed. A node is able to determine its own position using sources. The sources may include fixed and/or mobile beacons. Each of the sources is associated with a distance error and a position error. These errors, along with distance measurements between the node and each of the sources, are used to determine a position and a total positioning error, which reflects the accuracy of the determined position.

Peer-based positioning of mobile devices

One example method includes receiving at a client node of a federation a global machine-learning model that is to be trained by the client node using a training dataset that is local to the client node. In response to receiving the global machine-learning model, determining at the client node if the global machine-learning model is trending toward an overfitted state using a validation dataset. The overfitted state indicates that the global machine-learning model has not been received from a server that is part of the federation because of a client isolation attack. In response to determining that the global machine-learning model is trending towards the overfitting state, causing the client node to leave the federation. In response to determining that the global machine-learning model is not trending towards the overfitted state, training the global machine-learning model using the training dataset to thereby update the global machine-learning model.

Real-time event detection is performed on nodes in an environment using position data that is not available to a node in real time but is delayed. A node performs real time event detection by predicting a position of the node based at least in part on delayed position data. The delayed position data is aligned to other sensor data. Aligning the position data may include predicting a position based on dead reckoning and/or a machine learning model. One or more collections of data, each collection including sensor data and predicted position data, is input to a model that performs event detection.

One example method includes determining a system aggregate drift metric score based on aggregate drift metric scores received from near-edge nodes associated with a central node. The system aggregate drift metric score indicates a level of model drift across a logistics system. The system aggregate drift metric score is compared with a system drift threshold. Current datasets are received from the near-edge nodes when a system aggregate drift metric score is greater than the system drift threshold. A first dataset is generated comprising a joining of the current datasets received from the plurality of near-edge nodes. A second dataset is received from each the near-edge nodes. The first and second datasets are used to select a machine-learning (ML) model to deploy at each of the near-edge nodes.
