Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Bayesian Approach to Determining the Orientation of Sound-soft Obstacles with Phaseless Data via Wasserstein Distance
Wasserstein距离 贝叶斯方法 无相数据 软声障碍物
2022/12/9
We present a Bayesian approach to inverse scattering problems of reconstructing the rotation angle in clockwise direction of an acoustically sound-soft obstacle from phaseless far-field data in two di...
Columbia Engineering Researchers Use Acoustic Voxels to Embed Sound with Data
Columbia Engineering Researchers Acoustic Voxels Embed Sound with Data
2016/7/18
Columbia Engineering researchers, working with colleagues at Disney Research and MIT, have developed a new method to control sound waves, using a computational approach to inversely design acoustic fi...
Sound, Complete and Scalable Path-Sensitive Analysis
Static analysis path- and context-sensitive analysis strongest necessary/weakest sufficient conditions
2016/5/24
We present a new, precise technique for fully path- and contextsensitive program analysis. Our technique exploits two observations:First, using quantified, recursive formulas, path- and contextsensiti...
Making Sense of Sound: Unsupervised Topic Segmentation over Acoustic Input
Making Sense of Sound Unsupervised Topic Segmentation over Acoustic Input
2014/11/27
We address the task of unsupervised topic segmentation of speech data operating over raw acoustic information. In contrast to existing algorithms for topic segmentation of speech, our approach does no...
Now, University of Minnesota engineering researchers have developed a chip on which both sound wave and light wave are generated and confined together so that the sound can very efficiently control th...
A State Estimation Method for Sound Environment System with Unknown Observation Mechanism by Introducing Fuzzy Inference
State Estimation Sound Environment System Unknown Observation Mechanism Fuzzy Inference
2012/7/27
The observed phenomena in real sound environment system often contain uncertainty such as the additional external noise with unknown statistics. Furthermore, there is complex nonlinear relationship be...
Adaptive Method for State Estimation of Sound Environment System with Uncertainty and its Application to Psychological Evaluation
Adaptive Estimation Sound Environment System Uncertainty Psychological Evaluation
2010/3/16
The actual sound environment system exhibits various types of linear and non-linear characteristics, and it often contains uncertainty. Furthermore, the observations in the sound environment are often...
