Optimization of Trading Performance Using Both Brain State Models and Operational Performance Models
Publication number: 20240005398Abstract: A method includes generating a trading performance model for a trading activity involving a set of decisions by a set of expert traders. The trading performance model includes a set of input data sets, a set of data processing workflows operating on the input data sets, and a set of trading decision outputs resulting from interaction of the expert traders with a user interface representing the trading performance model. The method includes generating a brain state model representing a sequential set of brain states of the set of expert traders that characterize brain states measured during the interactions of the expert traders with the user interface representing the trading performance model, assessing the quality of the trading decisions, determining a preferred pattern of trader brain state sequences, and modifying a subsequent trading activity.Type: ApplicationFiled: June 28, 2023Publication date: January 4, 2024Inventors: Paul Sajda, Jacek Dmochowski, Pawel Gucik, Ben Londergan, Paul DeGuzman, Sam DeWitt -
Publication number: 20230309885Abstract: To identify physiological states that are predictive of a person's performance, a system provides physiological and behavioral interfaces and a data processing pipeline. Physiological sensors generate physiological data about the person while performing a task. The behavioral interface generates performance data about the person while performing the task. The pipeline collects the physiological and performance data along with reference data from a population of people performing the same or similar tasks. In various implementations, the physiological states are brain states. In one implementation, the pipeline computes bandpower ratios.Type: ApplicationFiled: February 28, 2023Publication date: October 5, 2023Inventors: David Bach, Suhas Chelian, Paul DeGuzman, Jacek Dmochowski, Amy Kruse, Will McBurnett, Steven L. Miller, Thomas F. Nugent, III, Paul Sajda

Publication number: 20220374739Abstract: A method of predicting response to a sensory stimulus includes, with a processor, automatically receiving behavioral data representing the response of a first population of subjects to a reference stimulus. Data representing the neurological responses of a second, different population of subjects to the reference sensory stimulus are received and processed to provide group-representative data indicating commonality between the neurological responses of at least two members of the second population. A mapping from the group-representative data to the received behavioral data is produced. Test data representing the neurological responses of a third population of subjects to a test sensory stimulus are received and processed to provide test group-representative data indicating commonality between the neurological responses to the test sensory stimulus of at least two members of the third population. The mapping is applied to the test group-representative data to provide predicted behavioral data.Type: ApplicationFiled: May 16, 2022Publication date: November 24, 2022Inventors: Lucas Parra, Jacek Dmochowski

Publication number: 20210022637Abstract: Methods are disclosed for determining an efficacy of a stimulus based on one or more measurable physiological responses to one or more stimuli including one or more stimulus features. Data is acquired on physiological responses of a group of one or more subjects to presentation of one or more stimuli including one or more stimulus features. The data on the one or more physiological responses of the one or more subjects is correlated with the presentation of the one or more stimulus features included in the one or more stimuli. The correlated data on the one or more physiological responses are associated with a separately-determined efficacy of the one or more stimuli to form a stimulus efficacy model. From this information, a projected efficacy of a stimulus is determinable by comparing one or more subsequently-measured physiological responses to the stimulus with the stimulus efficacy model.Type: ApplicationFiled: October 1, 2020Publication date: January 28, 2021Inventors: Lucas Parra, Paul Sajda, Paul Deguzman, Daniel Rosenthal, Charles Phillip Cloud, Jacek Dmochowski

Patent number: 8144896Abstract: A system that facilitates blind source separation in a distributed microphone meeting environment for improved teleconferencing. Input sensor (e.g., microphone) signals are transformed to the frequency-domain and independent component analysis is applied to compute estimates of frequency-domain processing matrices. Modified permutations of the processing matrices are obtained based upon a maximum magnitude based de-permutation scheme. Estimates of the plurality of source signals are provided based upon the modified frequency-domain processing matrices and input sensor signals. Optionally, segments during which the set of active sources is a subset of the set of all sources can be exploited to compute more accurate estimates of frequency-domain mixing matrices. Source activity detection can be applied to determine which speaker(s), if any, are active.Type: GrantFiled: February 22, 2008Date of Patent: March 27, 2012Assignee: Microsoft CorporationInventors: Zicheng Liu, Philip Andrew Chou, Jacek Dmochowski
