Patent number: 11893354Abstract: The present invention provides for improving training dataset by identifying errors in training dataset and generating improvement recommendations. In operation, the present invention provides for identifying and correcting duplicate utterances in training dataset comprising utterances-intent pairs. Further, a plurality of Natural Language ML models are trained with the corrected training dataset to obtain diverse set of trained ML models. Each utterance of training dataset are fed as input to trained ML models, and a probability of error associated with each utterances-intent pairs of training dataset are evaluated based on analysis of respective intent predictions received from each of the trained ML models. Furthermore, spelling errors in the dataset are identified and data-imbalances in the training dataset are evaluated.Type: GrantFiled: June 15, 2021Date of Patent: February 6, 2024Assignee: COGNIZANT TECHNOLOGY SOLUTIONS INDIA PVT. LTD.Inventors: Jithu R Jacob, Siddhartha Das

Publication number: 20220390401Abstract: A method of preparing electronically conductive polyaniline that forms a self-supporting dispersion in water is described. The binder-free dispersion was coated on a pair of interdigitated metal electrodes to form a gas sensing layer of a chemical sensor. The chemical sensor utilizes electrochemical impedance spectroscopy (EIS) to detect and characterize a chemical compound in a gaseous state in contact with the sensing layer. Impedance of the sensing layer is measured over a range of alternating current frequencies. The impedance data allows identification and concentration of the chemical compound to be determined when compared to reference impedance data. The analysis of the impedance measurements is adaptable to machine learning.Type: ApplicationFiled: May 11, 2021Publication date: December 8, 2022Inventors: Tim Erdmann, Angelo Milone, Linda Karin Sundberg, Siddhartha Das, Ronald R.

Patent number: 11221318Abstract: Provided is a system for detection and discrimination of gases, such as volatile organic compounds (VOCs), in a sample comprising two chambers, a first chamber equipped with a crystalline microporous material (CMM) and a second chamber equipped with a gas detector. A gas sample is introduced first into the second chamber for detection by the gas detector and is then re-routed to the first chamber for adsorption/desorption on the CMM. The gas detector in the second chamber produces electronic signals that correspond to the adsorption/desorption profile for the gas, which allows for discrimination of the gas in the sample from other possible gas samples.Type: GrantFiled: July 24, 2019Date of Patent: January 11, 2022Assignee: International Business Machines CorporationInventors: Siddhartha Das, Andrea Fasoli, Luisa Dominica Bozano

Patent number: 5540346Abstract: Manufacturing techniques for forming waveguide channels and devices. A trench is formed in a cladding layer through an opening in a conductive layer. The trench is then filled with an active waveguide polymer and the conductive layer is patterned such that the active waveguide polymer may be poled. Also, a trench may be isotropically etched through a cladding layer to an underlying etch stop layer. The etch stop layer is thereafter removed from within the trench region to expose a previously formed, smooth, underlying cladding layer. Finally, a waveguide formed in a cladding layer, bounded in width by an overlying barrier layer, underlies a masking layer having a gap formed therein. Within the gap, a portion of the waveguide channel along with juxtaposing sections of the barrier layer are exposed. An etch is thereafter performed to remove the portion of the waveguide polymer in the waveguide channel bounded by both the masking layer and the barrier layer.Type: GrantFiled: June 28, 1995Date of Patent: July 30, 1996Assignee: Intel CorporationInventors: Harry H.
