Cortical surface electrical potentials are composed of multiple bandlimited frequency components, including high-gamma

Posted by klaurent July 23, 2022August 1, 2022UCSF

Kavli Affiliate: Kristofer Bouchard, Edward Chang | Authors: Jesse A Livezey, Ahyeon Hwang, Kseniya Usovich, Maximilian Dougherty, Edward F Chang and Kristofer E Bouchard | Summary: A common challenge in neuroscience is how to decompose noisy, multi-source signals measured in experiments into biophysically interpretable components. Analysis of cortical surface electrical potentials (CSEPs) measured using electrocorticography […]

A Taxonomy of Recurrent Learning Rules

Posted by klaurent July 23, 2022Delft

Kavli Affiliate: Sander Otte| First 5 Authors: Guillermo Martín-Sánchez, Guillermo Martín-Sánchez, , , | Summary:Backpropagation through time (BPTT) is the de facto standard for training recurrent neural networks (RNNs), but it is non-causal and non-local. Real-time recurrent learning is a causal alternative, but it is highly inefficient. Recently, e-prop was proposed as a causal, local, […]

Measurements of the branching fraction, isospin asymmetry, and lepton-universality ratio in $B to J/ψK$ decays at Belle II

Posted by klaurent July 22, 2022Tokyo

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, F. Abudinén, I. Adachi, R. Adak, K. Adamczyk | Summary: We report a study of $B to J/psi(ell^{+}ell^{-})K$ decays, where $ell$ represents an electron or a muon, using $e^{+}e^{-}$ collisions at the $Upsilon(4S)$ resonance. The data were collected by the Belle II experiment at […]

A quantum electromechanical interface for long-lived phonons

Posted by klaurent July 22, 2022Caltech

Kavli Affiliate: Mohammad Mirhosseini | Summary:Controlling long-lived mechanical oscillators in the quantum regime holds promises for quantum information processing. Here, we present an electromechanical system capable of operating in the GHz-frequency band in a silicon-on-insulator platform. Relying on a novel driving scheme based on an electrostatic field and high-impedance microwave cavities based on TiN superinductors, […]

Two-Stage Fine-Tuning: A Novel Strategy for Learning Class-Imbalanced Data

Posted by klaurent July 22, 2022Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Taha ValizadehAslani, Yiwen Shi, Jing Wang, Ping Ren, Yi Zhang | Summary: Classification on long-tailed distributed data is a challenging problem, which suffers from serious class-imbalance and hence poor performance on tail classes with only a few samples. Owing to this paucity of samples, learning on the […]
