Publication number: 20250131320Abstract: Systems and methods for identifying substitute elements for computer-implemented processes are disclosed. A substitution request identifying an anchor element is received. A set of candidate substitution elements is generated by a trained candidate selection model configured to receive the anchor element, a feature set, and a set of catalog elements. The set of candidate substitution elements is ranked by a trained ranking model configured to receive the anchor element, the feature set, and the set of candidate substitution elements. At least one substitution element is selected from the set of candidate substitution elements and feedback data representative of the suitability of the selected at least one substitution element with respect to the anchor element is received. At least one of the trained candidate selection model or the trained ranking model is updated by applying an iterative training process incorporating at least a portion of the feedback data.Type: ApplicationFiled: October 18, 2023Publication date: April 24, 2025Inventors: Priyanshu Chandra, Nikhil Kumar, Romal Rajesh Jaiswal, Shubham Jain, Kamiya Motwani, Rahul Ghosh, Kannan Achan

Publication number: 20250113123Abstract: Networks and network elements having an optical power control block, service and power control orchestrator, used to activate, deactivate and perform optical control of channels is disclosed hereby. The invention introduces the idea that, user created service would be activated or deactivated in smaller increments which would help to mitigate power transient on the transmission line. This approach of incremental activation or deactivation would help to correct against undesirable power changes on rest of the optical channels sharing the common optical path. In addition, it provides a way to monitor the health of increment under activation throughout the activation and if necessary optical power thresholds being not met, it can be rolled back. During the process of such an incremental activation or deactivation, the already activated portion of the channel would continue to be optically controlled independently.Type: ApplicationFiled: September 30, 2024Publication date: April 3, 2025Inventors: Aryabhata Deshpande, Nikhil Kumar Satyarthi, Baranidhar Ramanathan
