Direct Feedback Alignment With Sparse Connections for Local Learning [PDF]

Frontiers in Neuroscience, 2019
Recent advances in deep neural networks (DNNs) owe their success to training algorithms that use backpropagation and gradient-descent. Backpropagation, while highly effective on von Neumann architectures, becomes inefficient when scaling to large ...

Controlling entanglement by direct quantum feedback [PDF]

Physical Review A, 2008
We discuss the generation of entanglement between electronic states of two atoms in a cavity using direct quantum feedback schemes. We compare the effects of different control Hamiltonians and detection processes in the performance of entanglement ...

Global and regional importance of the direct dust-climate feedback [PDF]

Nature Communications, 2018
Feedbacks between desert dust and climate might have amplified past climate changes, yet their role in future climate change is unclear. Here the authors find that dust feedbacks could play a key role in the future climates of Northern Africa, the Sahel,

Nonlinear cochlear mechanics without direct vibration-amplification feedback [PDF]

Physical Review Research, 2020
Recent in vivo recordings from the mammalian cochlea indicate that although the motion of the basilar membrane appears actively amplified and nonlinear only at frequencies relatively close to the peak of the response, the internal motions of the organ of

Cardiorespiratory monitoring during neonatal resuscitation for direct feedback and audit [PDF]

Frontiers in Pediatrics, 2016
Neonatal resuscitation is one of the most frequently performed procedures and it is often successful if the ventilation applied is adequate. Over the last decade, interest in seeking objectivity in evaluating the infant’s condition at birth or the ...

Comparative Effects of Direct and Metalinguistic Computer-Mediated Feedback on L2 Learners’ Writing Ability and Willingness-to-Write [PDF]

Journal of Modern Research in English Language Studies, 2022
The present study investigated the probable effects of asynchronous direct and metalinguistic computer-mediated corrective feedback (CMCF) on the writing ability (WA) and willingness-to-write (WTW) of upper-intermediate L2 learners.

The Differential Effects of Direct and Indirect Corrective Feedback on Impulsive and Reflective EFL Learners’ Writing Accuracy [PDF]

Journal of English Language Teaching and Learning, 2023
Given the significant role of corrective feedback and individual differences in the process of foreign language acquisition, in the present study we set out to investigate the effect of direct and indirect corrective feedback on impulsive and reflective ...
