Ringing ReLUs: Harmonic Distortion Analysis of Nonlinear Feedforward Networks

no code implementations ICLR 2021 Christian H.X. Ali Mehmeti-Göpel, David Hartmann, Michael Wand

In this paper, we apply harmonic distortion analysis to understand the effect of nonlinearities in the spectral domain.

Meta-Learning for Recalibration of EMG-Based Upper Limb Prostheses

no code implementations ICML Workshop LifelongML 2020 Krsto Proroković, Michael Wand, Jürgen Schmidhuber

An EMG-based upper limb prosthesis relies on a statistical pattern recognition system to map the EMG signal of residual forearm muscles into the appropriate hand movements.


Deep Non-Line-of-Sight Reconstruction

no code implementations CVPR 2020 Javier Grau Chopite, Matthias B. Hullin, Michael Wand, Julian Iseringhausen

We demonstrate that our feed-forward network, even though it is trained solely on synthetic data, generalizes to measured data from SPAD sensors and is able to obtain results that are competitive with model-based reconstruction methods.

Progressive Stochastic Binarization of Deep Networks

1 code implementation3 Apr 2019 David Hartmann, Michael Wand

By focusing computational attention using progressive sampling, we reduce inference costs on ImageNet further by a factor of up to 33% (before network pruning).

Improving Speaker-Independent Lipreading with Domain-Adversarial Training

no code implementations4 Aug 2017 Michael Wand, Juergen Schmidhuber

We present a Lipreading system, i. e. a speech recognition system using only visual features, which uses domain-adversarial training for speaker independence.

Lipreading with Long Short-Term Memory

no code implementations29 Jan 2016 Michael Wand, Jan Koutník, Jürgen Schmidhuber

Lipreading, i. e. speech recognition from visual-only recordings of a speaker's face, can be achieved with a processing pipeline based solely on neural networks, yielding significantly better accuracy than conventional methods.
