This disclosure relates generally to system and methods for dynamic scheduling and rescheduling using heterogeneous multi-agent fleet. The embodiments of present disclosure herein address unresolved problem of task allocation using a single solution which is not sufficient for handling various scenarios of multi-agent task allocation problems. For instance, the task allocation becomes more challenging in a scenario where each task has a deadline associated with it and execution time of the tasks cannot be pre-computed as they are dependent on previous tasks. The method of present disclosure provides a scalable solution for dynamic scheduling and rescheduling that handles tasks with multiple pickup and drop locations and dynamic execution time using the agents with heterogeneous speed in a more efficient manner, reducing indirect operating costs and increasing revenue potential while minimizing additional penalty due to run time delays that an agent may encounter.

Accuracy of transcript is of foremost importance in Automatic Speech Recognition (ASR). State of the art system mostly rely on spelling correction based contextual improvement in ASR, which is generally a static vocabulary based biasing approach. Embodiments of the present disclosure provide a method and system for visual context aware ASR. The method provides biasing using shallow fusion biasing approach with a modified beam search decoding technique, which introduces a non-greedy pruning strategy to allow biasing at the sub-word level. The biasing algorithm brings in the visual context of the robot to the speech recognizer based on a dynamic biasing vocabulary, improving the transcription accuracy. The dynamic biasing vocabulary, comprising objects in a current environment accompanied by their self and relational attributes, is generated using a bias prediction network that explicitly adds label to objects, which are detected and captioned via a state of the art dense image captioning network.
