Abstract: Embodiments of the present invention provide an approach for applying cognitive diagnostic modeling (CDM) and deep learning algorithms to improve knowledge transfer (KT) progress. Specifically, the approach aims to improve the process of transferring knowledge by breaking down a learning task into smaller subtasks that are related to a specific learning goal. The provided responses for each subtask are then evaluated using a deep learning algorithm, which generates a continuous score based on the difference between the provided response and the expected response. Each continuous score is then converted into a binary value to obtain a set of binary values. Based on the set of binary values, a diagnostic report is generated that reflects the progress of knowledge transfer for the assigned learning task. This approach allows for a more detailed and accurate assessment of the learning process, which can help to identify areas where further improvement is needed.

Abstract: A method and a device for reducing noise of a wireless-earphone, a wireless-earphone and a computer-readable storage medium are provided. In the method, a first electromagnetic signal from a slave earphone is received, and the first electromagnetic signal is converted to an audio signal. The first electromagnetic signal is obtained by a coil inducing an audio signal acquired by a microphone in the slave earphone. A to-be-denoised earphone is determined based on audio signals acquired by microphones in the earphones. It is determined whether an audio signal acquired by a microphone in the to-be-denoised earphone has a voice feature. Noise reduction processing is performed on the audio signal acquired by the microphone in the to-be-denoised earphone by using a filter in a case that the audio signal acquired by the microphone in the to-be-denoise earphone has the voice feature.
