Patent number: 12277510Abstract: Quantum Information Processing (QIP) with the availability of Noisy Intermediate-Scale Quantum (NISQ) device(s) are available to work on quantum algorithms. Different problems, which are hard to solve by classical computation, but can be sped up (significantly in some cases) are also being populated. However, current approaches solve only two cluster max-cut problems. Mining the two cluster Max-Cut problem within the framework of quantum Ising model, embodiments of the present disclosure solve Quadratic Unconstrained D-ary Optimization (QUDO) problems by quantum computing with the identification of an appropriate Hamiltonian. More specifically, the problem is mapped to an Ising model to obtain a d-ray Quantum Ising Hamiltonian. The d-ray Quantum Ising Hamiltonian is then executed on one or more qudit processors, to obtain one or more resultant quantum states which are measured in a qudit computational basis to obtain at least one solution.Type: GrantFiled: April 2, 2021Date of Patent: April 15, 2025Assignee: Tata Consultancy Services LimitedInventors: Sayantan Pramanik, Mariswamy Girish Chandra

Publication number: 20250068892Abstract: Existing Convolutional Dictionary Learning (CDL) based machine fault classification do not utilize label information while learning the dictionary, hence the representation learned are not class-discriminative. Method and system disclosed herein provide a label-consistent convolutional dictionary learning approach for machine fault classification. The approach involves generating a training data for a classifier, wherein coefficients forming a plurality of class-discriminative features form the training data. The training data is then used to train a classifier, which is then used to perform machine fault classification for a given test data.Type: ApplicationFiled: August 2, 2024Publication date: February 27, 2025Applicant: Tata Consultancy Services LimitedInventors: SAURABH SAHU, KRITI KUMAR, ACHANNA ANIL KUMAR, MARISWAMY GIRISH CHANDRA, ANGSHUL MAJUMDAR

Publication number: 20250012675Abstract: The disclosure generally relates to methods and systems for graph assisted unsupervised domain adaptation for machine fault diagnosis. The present disclosure solves the technical problems in the art using a Graph Assisted Unsupervised Domain Adaptation (GA-UDA) technique for the machine fault diagnosis. The GA-UDA technique carries out the domain adaptation in two stages. In the first stage, a Class-wise maximum mean discrepancy (CMMD) loss is minimized to transform the data from both source and target domains to a shared feature space. In the second stage, the augmented transformed (projected) data from both the source and the target domains are utilized to construct a joint graph. Subsequently, the labels of target domain data are estimated through label propagation over the joint graph. The GA-UDA technique of the present disclosure helps in addressing significant distribution shift between the two domains.Type: ApplicationFiled: June 25, 2024Publication date: January 9, 2025Applicant: Tata Consultancy Services LimitedInventors: NAIBEDYA PATTNAIK, KRITI KUMAR, MARISWAMY GIRISH CHANDRA, ACHANNA ANIL KUMAR

Publication number: 20240151690Abstract: In industrial inspection scenarios, early detection of machine malfunction is extremely essential as it helps in preventing any significant damage and the associated economic losses. Embodiments herein provide a method and system for an acoustic based anomaly detection in industrial machines using a beamforming and a sequential transform learning. Herein, the system employs two-stage multi-channel source separation technique that uses the well-known delay and sum beamforming followed by a recent data-driven sequential transform learning (STL) approach to obtain clean sources. The STL is a solution to linear state-space model where operators/matrices are learnt from data and is used here to model the dynamics of time-varying source signals for source separation. Subsequently, a reference template matching is employed on each separated source to detect an anomaly.Type: ApplicationFiled: September 25, 2023Publication date: May 9, 2024Applicant: Tata Consultancy Services LimitedInventors: Saurabh SAHU, Mariswamy Girish CHANDRA, Kriti KUMAR, Achanna Anil KUMAR, Angshul MAJUMDAR
