Publication number: 20230376793Abstract: Systems, methods, and software for training a machine learning model. The system utilizes training data to train the machine learning model across multiple epochs. The system prepares additional training data by: selecting a set of samples that are unclassified, operating the machine learning model to predict labels that classify the samples, determining an uncertainty of the labels predicted by the machine learning model, calculating a ranking score for each of the samples in the set, selecting a subset of the samples that have more than a threshold ranking score, and submitting the subset to a client for replacement labels. The system receives the replacement labels from the client, and trains the machine learning model, using the subset of the samples as the training data. The labels predicted by the machine learning model for the subset are replaced with corresponding replacement labels from the client.Type: ApplicationFiled: May 20, 2022Publication date: November 23, 2023Inventors: Gerald Lehmann, Dan Kushnir, Maria Able, Gerald Meyer, Huseyin Uzunalioglu, Robert Seidl

Publication number: 20200202210Abstract: The present disclosure describes systems and methods for training a neural network. A representative embodiment includes selecting one or more candidate data points to label from a pool set of unlabeled data points where the candidate data point is selected such that the selective addition of the candidate data point and its correct label to a training set of correctly labeled data points used to train the neural network most reduces the label entropy of a test set of unlabeled data points used to test the neural network. The active learning neural network is further (e.g., iteratively) trained using the augmented set of correctly labeled training data points.Type: ApplicationFiled: December 24, 2018Publication date: June 25, 2020Inventors: Dan Kushnir, Tam Nguyen

Patent number: 10541880Abstract: Systems and methods for regulating data traffic using active learning techniques. In one embodiment, a global monitor communicates with a plurality of sensors over a wide area network. The global monitor builds a global model for a data analytics service that maps elements to values based on data reported by the sensors. The global monitor generates a query for the data from the sensors, selects one or more candidate elements from the elements in the global model, generates a global policy specifying that the data requested from the sensors is limited to the data targeted to the candidate element(s), and sends the query indicating the global policy to the sensors. The global monitor receives the data targeted to the candidate element(s) from the sensors according to the global policy, and adjusts the global model based on the data targeted to the candidate element(s).Type: GrantFiled: December 12, 2017Date of Patent: January 21, 2020Assignee: Nokia Technologies OyInventor: Dan Kushnir

Patent number: 9571976Abstract: Embodiments described herein provide improvements to the accuracy of location estimates. In one embodiment, an apparatus stores a first plurality of RF signal strength values that are mapped to known locations, and stores a second plurality of RF signal strength values that are not mapped to known locations. The apparatus estimates locations where the second plurality of RF signal strength values was measured based on the first plurality of RF signal strength values and their corresponding known locations, calculates an uncertainty for the estimated locations, and identifies an estimated location having a highest uncertainty. The apparatus directs a measurement device to measure an RF signal strength value at a known location that corresponds with the estimated location, and adds the RF signal strength value to the first plurality of RF signal strength values to reduce an uncertainty in subsequent estimates of locations within the broadcast area.Type: GrantFiled: December 17, 2015Date of Patent: February 14, 2017Assignee: Alcatel-Lucent USA Inc.Inventor: Dan Kushnir

Patent number: 9159077Abstract: A method for deriving a composite tie metric for an edge between nodes of a telecommunication call graph includes receiving descriptive data with original values for descriptive attributes associated with a telecommunication call graph formed by edges between nodes. Each edge relates to two nodes. Each original value relates to an edge and a descriptive attribute forming an edge-attribute pair for the corresponding original value. The descriptive data is stored in a local storage device. Scaling factors for each descriptive attribute are determined taking into account a distribution of the original values for the corresponding descriptive attribute and a common base for the descriptive attributes. Weighting factors are determined for each descriptive attribute. The composite tie metric is computed for an edge based on the original value, scaling factor, and weighting factor for the descriptive attributes.Type: GrantFiled: July 25, 2012Date of Patent: October 13, 2015Assignee: Alcatel LucentInventors: Veena B.
