Abstract: A method and system for providing end-to-end multi-task denoising for joint signal distortion ratio (SDR) and perceptual evaluation of speech quality (PESQ) optimization is herein disclosed. According to one embodiment, an method includes receiving a noisy signal, generating a denoised output signal, determining a signal distortion ratio (SDR) loss function based on the denoised output signal, determining a perceptual evaluation of speech quality (PESQ) loss function based on the denoised output signal, and optimizing an overall loss function based on the PESQ loss function and the SDR loss function.

Abstract: A triboelectric generator includes a first electrode and a second electrode spaced apart from each other, a first charging part on the first electrode, a second charging part on the second electrode, and a grounding unit. The first charging part and the second charging part may be configured to contact each other through a sliding motion. The grounding unit may be configured to intermittently connect a charge reservoir to the second charging part. The grounding unit may be configured to vary the electric potential of the second charging part so as to amplify current flowing between electrodes of the triboelectric generator.
