Abstract: Technical interviewing is important for organizations for assessing a candidate to make hiring decision. For effective technical interviewing, predicting difficulty of long form technical questions is crucial. The present disclosure provides systems and methods for predicting difficulty of long form technical questions using weak supervision from textbooks. Further, zero shot pre-trained large language models and unsupervised template-based technique are used for generating questions. Furthermore, a difficulty score is assigned to the generated questions based on context difficulty and task difficulty. The context difficulty for the generated questions is computed using hierarchical structure of the textbooks, and the task difficulty is computed by determining a similarity between the generated questions and Bloom's taxonomy levels.

Abstract: The present disclosure a method for document structure based unsupervised long-form technical question generation. Initially, the system receives a textbook document. Further, a PDF metadata is extracted from the textbook document using a Natural Language Processing (NLP) technique. Further, a plurality of structures from the textbook document based on the PDF metadata using an NLP based filtering technique. Further, a plurality of index based question templates and Table of Contents (TOC) based question templates are obtained from a plurality of predefined question templates using the plurality of structures. Further, the generated plurality of long-form technical questions are generated using the obtained index and TOC based question templates. The plurality of long-form technical questions are further evaluated by the system using plurality of metrics.

Abstract: The present invention is a magnetic field gradient coil, assembly and system for use in imaging techniques requiring a magnetic field gradient. The magnetic field gradient coil includes a plurality of conductors wherein each conductor is arranged in a substantially spatially parallel relationship with respect to the other conductors for generating a magnetic field gradient. The plurality of substantially spatially parallel conductors may be integrated in a flexible structure. The flexible structure may be ribbon cable. The magnetic field gradient coil may further include a plurality of layers of the substantially spatially parallel conductors wherein each layer substantially overlies the preceding layer. A selected number of the substantially spatially parallel conductors may be electrically connected in parallel thereby providing a desired switching speed, or a desired field gradient strength, or a desired match of the output impedance of an electrical power source.
