    Abstract: A system for retrieving information from an instructional document, includes a processor configured to: receive a query from a user; compare the query with one or more text sections in the instructional document; obtain, from the one or more text sections, top x text sections relevant to the query using a pre-trained encoder; compare the query with one or more images in the instructional document; obtain, from the images, top y images relevant to the query; generate top y image-text sections based on the top y images; obtain top k sections from the top x text sections and the top y image-text sections; obtain one or more most relevant sections from the top k sections using a domain-specific pre-trained encoder and a sequential classification model; and generate an answer based on the one or more most relevant sections and device context information using the domain-specific pre-trained encoder.

    Abstract: A system and method are provided for generating a signal strength map by a master device. The method includes operations for receiving, from a set of fixed transmitting devices, registration information including location, a type of signal and a device identifier (ID), receiving, from at least one receiving device, a set of parameters including location of the receiving device, strength of a first signal as received by the receiving device at a first location, type of the first signal, strength of a second signal as received by the receiving device at the first location, and type of the second signal, receiving at least one of the first or the second signal from at least one of the fixed transmitting devices, storing the received set of parameters, and generating a signal strength map representing strength of the first and the second signals at the first location.
