QIP 20222022Phase estimation is a quantum algorithm for measuring the eigenvalues of a Hamiltonian. We propose and rigorously analyze a randomized phase estimation algorithm with two distinctive features. First, our algorithm has complexity independent of the number of terms L in the Hamiltonian. Second, unlike previous L-independent approaches, such as those based on qDRIFT, all sources of error in our algorithm can

IEEE Transactions on Electromagnetic Compatibility2022As more compact designs and more assembled function modules are utilized in modern electronic devices, radiofrequency interference (RFI) source reconstruction is becoming more challenging because different noise sources may contribute simultaneously. This article presents a novel methodology to reconstruct multiple random noise sources on a real-world product, including several double-data-rate (DDR) memory

WACV 20222022This work presents a No-Reference model to detect audio artifacts in video. The model, based upon a Pretrained Audio Neural Network, classifies a 1-second audio segment as either No Defect, Audio Hum, Audio Hiss, Audio Distortion or Audio Clicks. The model achieves a balanced accuracy of 0.986 on our proprietary simulated dataset.

AAAI 2022 Workshop on Combining Learning and Reasoning: Programming Languages, Formalisms, and Representations (CLeaR)2022Language-enabled AI systems can answer complex, multihop questions to high accuracy, but supporting answers with evidence is a more challenging task which is important for the transparency and trustworthiness to users. Prior work in this area typically makes a trade-off between efficiency and accuracy; state-of-the-art deep neural network systems are too cumbersome to be useful in large-scale applications

ICCE 20222022We introduce a two-stage approach using LSTM for voice activity detection with sound event classification. This approach proves to be effective when training data is limited. Moreover, it achieves better performance than pre-trained model using large-scale data set (AudioSet). Apart from clip-level accuracy, we also introduce two metrics for evaluating overall audio segmentation accuracy: mean IoU, and
