Toddlers' ability to map the meaning of new words in multi-talker environments

Justine Dombroski, Rochelle S. Newman
2014 Journal of the Acoustical Society of America  
Children showed similar accuracy in all three conditions, suggesting that even at a 0 dB SNR, children were successfully able to learn new words.  ...  Three groups of children aged 32-36 months were taught two new words either in quiet, or in the presence of multi-talker babble at a þ5 or 0 dB signal-to-noise ratio (SNR).  ...  Do you see the coopa? Find the coopa! Coopa!"). On baseline trials, the voice did not instruct children to look at a particular object ("Wow, look at that! Do you see that? Ooooo! look!").  ...

Sharper signals: how machine learning is cleaning up microscopy images

Amber Dance
2021 Nature  
"Then came the deep-learning era," says Elad. By passing the images to computers and allowing them to work out the best de-noising approach, researchers have begun to see striking results.  ...  Then, the machine-learning algorithm attempts to de-noise by predicting the centre value for that patch on the basis of surrounding pixels.  ...  "It's really the biologist, the expert, who decides what you're going to use and not use."  ...

Image denoising with multi-layer perceptrons, part 2: training trade-offs and analysis of their mechanisms [article]

Harold Christopher Burger, Christian J. Schuler, Stefan Harmeling
2012 arXiv   pre-print
By analysing the activation patterns of the hidden units we are able to make observations regarding the functioning principle of multi-layer perceptrons trained for image denoising.  ...  Image denoising can be described as the problem of mapping from a noisy image to a noise-free image.  ...  The feature generators look similar to those learned by other MLPs. However, the feature detectors again look somewhat different: many seem to focus on the center area of the input patch.  ...

The Negative Impact of Noise on Adolescents' Executive Function: An Online Study in the Context of Home-Learning During a Pandemic

Brittney Chere, Natasha Kirkham
2021 Frontiers in Psychology  
UNICEF estimates that 1.6 billion children across the world have had their education impacted by COVID-19 and have attempted to continue their learning at home.  ...  In particular, adolescents coming from noisier homes were more likely to report that they studied in a noisy room and that they were annoyed by noise when studying.  ...  Both authors contributed to manuscript revision, read, and approved the submitted version.  ...

Deep Convolutional Generative Adversarial Network for Procedural 3D Landscape Generation Based on DEM [chapter]

Andreas Wulff-Jensen, Niclas Nerup Rant, Tobias Nordvig Møller, Jonas Aksel Billeskov
2018 Lecture Notes of the Institute for Computer Sciences, Social Informatics and Telecommunications Engineering  
Perlin noise is especially interesting as it has been used to generate game maps in previous productions [3, 4] .  ...  The diversity test showed the generated maps had a significantly greater diversity than the Perlin noise maps. Afterwards the heightmaps was converted to 3D maps in Unity3D.  ...  The results got significantly worse when it was set to 0.002, where the network did not learn at all and continued to generate noise.  ...

not when the signal-to-noise ratio (SNR) was 5 dB.  ...  Toddlers (28-to 30-month-olds; n = 26) successfully learned novel words with a 5-dB SNR when they initially heard the labels embedded in fluent speech without background noise, before they were mapped  ...  In this first look at early word learning when background speech is present, we have begun to understand some of the vulnerabilities of learning mechanisms involved in word learning.  ...

Learning to Avoid Errors in GANs by Manipulating Input Spaces [article]

Alexander B. Jung
2017 arXiv   pre-print
The core idea is to apply small changes to each noise vector in order to shift them away from areas in the input space that tend to result in errors.  ...  In this paper, we instead explore methods that enable GANs to actively avoid errors by manipulating the input space.  ...  We train each experiment for 100k batches at a learning rate of 0.0005, followed by 200k batches at a learning rate of 0.0001.  ...

2013 2013 IEEE Conference on Computer Vision and Pattern Recognition  
In a second (and arguably more difficult) step, one then needs to remove the colored noise, typically using a cleverly engineered algorithm.  ...  This step amplifies and colors the noise, and corrupts the image information.  ...  The radius of the actual PSF can be estimated by looking at the position of the first zero-frequency in Fourier domain.  ...
