Publication number: 20240112096Abstract: The present disclosure provides a system and method for delay prediction for scheduled public transport. A multi-architectural deep learning approach has been used to predict the delays of a queried vehicle in the scheduled public transport. For this, historical operational data is transformed into temporal, and spatiotemporal data. While, the spatial data is obtained from geographical information. The system uses different combinations of neural networks architectures. A regressor model uses three separate kinds of architecture. One component is the Fully Connected Neural Network (FCNN), which is good at learning from static features, the second is the Long Short Term Memory (LSTM) network which is good at learning from temporal features, and the third is the 3D Convolutional Neural Network (3DCNN) which is good at learning from spatiotemporal features. Learned encoding from each are fed to another FCNN to produce the predicted delay value.Type: ApplicationFiled: August 24, 2023Publication date: April 4, 2024Applicant: Tata Consultancy Services LimitedInventors: ROHITH REGIKUMAR, PRIYANGA KASTHURIRAJAN, RAJESH JAYAPRAKASH, ARVIND RAMANUJAM

Publication number: 20230401442Abstract: The present disclosure predicts a delay associated with a vehicle. Conventional methods are mainly mathematical based and machine learning based networks are not predicting delay accurately. Initially, the present disclosure Initially, the system receives a user query comprising an expected delay of a target vehicle in at least one target station. Further, a real time data associated with the user query in a predefined horizon is obtained. Further, a spatial feature vector, a temporal feature vector and spatiotemporal features are extracted based on the real time data using a feature extraction technique. Finally, the expected is predicted based on the plurality of features using a trained adversarial regression model, wherein the trained adversarial regression model comprises a critic network and a regressor network. The regressor network is trained with a plurality of architectures and a best architecture with minimum Mean Absolute Error (MAE) is selected for delay prediction.Type: ApplicationFiled: May 16, 2023Publication date: December 14, 2023Applicant: Tata Consultancy Services LimitedInventors: KRISHNAN SATHEESH, ROHITH REGIKUMAR, ARVIND RAMANUJAM, RAJESH JAYAPRAKASH

Publication number: 20230125620Abstract: HVAC control system's supervisory control is crucial for energy-efficient thermal comfort in buildings. The control logic is usually specified as ‘if-then-that-else’ rules that capture the domain expertise of HVAC operators, but they often have conflict that may lead to sub-optimal HVAC performance. Embodiments of the present disclosure provide a method and system for optimized Heating, ventilation, and air-conditioning (HVAC) control using domain knowledge combined with Deep Reinforcement Learning (DRL). The system disclosed utilizes Deep Reinforcement Learning (DRL) for conflict resolution in a HVAC control in combination with domain knowledge in form of control logic. The domain knowledge is predefined in an Expressive Decision Tables (EDT) engine via a formal requirement specifier consumable by the EDT engine to capture domain knowledge of a building for the HVAC control.Type: ApplicationFiled: September 26, 2022Publication date: April 27, 2023Applicant: Tata Consultancy Services LimitedInventors: SAGAR KUMAR VERMA, SUPRIYA AGRAWAL, VENKATESH RAMANATHAN, ULKA SHROTRI, SRINARAYANA NAGARATHINAM, RAJESH JAYAPRAKASH, AABRITI DUTTA

Patent number: 11623527Abstract: Vehicle-to-Grid (V2G) technologies are being adopted to reduce peak demand and to take over as energy sources during grid instability. It is necessary to estimate attributes of electric vehicle trips and residual battery charge in order to correctly predict spatio-temporal availability of energy from EVs to form a micro grid. However, it may not be feasible to get the required attributes for all vehicles in a city-scale traffic scenario. Embodiments of the present disclosure and system address the problem of accurately estimating the local energy reserve that is available from parked EVs during a given time of the day. In addition, the system also determines which neighborhoods have the potential to form micro grids using the parked EVs during a given time period. This will help grid operator(s) to plan and design smart grids which can create EV-powered micro grids in neighborhoods during periods of peak demand or during disruptions.Type: GrantFiled: June 27, 2018Date of Patent: April 11, 2023Assignee: TATA CONSULTANCY SERVICES LIMITEDInventors: Arvind Ramanujam, Pandeeswari Indumathi Sankaranarayanan, Arunchandar Vasan, Rajesh Jayaprakash, Venkatesh Sarangan, Anand Sivasubramaniam
