Latest Patents

One of his latest patents is titled "Infer text classifiers for large text collections." This invention provides an approach that calculates at least one weighting factor based on a word frequency analysis of an unlabeled document against a set of word frequencies corresponding to a set of labeled documents. The method computes an a posteriori classification probability of the unlabeled document based on the weighting factor and creates an inferred classifier based on this probability. The approach ultimately classifies the unlabeled document using the inferred classifier.

Another significant patent is "Detecting motion-sensor data anomalies." This invention focuses on detecting anomalies in motion-sensor data by registering an event associated with received motion-detector sensor data at a current timestamp. It calculates a timestamp delta between a previous timestamp and the current timestamp, counting transitions between a set of timestamp deltas using a finite state machine. The anomaly detection process also utilizes a Markov chain transition matrix to determine the probability of transitioning from a current state to a next state associated with the event, registering an anomaly when this probability is less than a predetermined value.
