Intelligent Matrix Exponentiation
Thomas Fischbacher, Iulia M. Comsa, Krzysztof Potempa +3
We present a novel machine learning architecture that uses the exponential of a single input-dependent matrix as its only nonlinearity. The mathematical simplicity of this architec…
Committee Draft of JPEG XL Image Coding System
Alexander Rhatushnyak, Jan Wassenberg, Jon Sneyers +15
JPEG XL is a practical approach focused on scalable web distribution and efficient compression of high-quality images. It provides various benefits compared to existing image forma…
Temporal Coding in Spiking Neural Networks with Alpha Synaptic Function: Learning with Backpropagation
Iulia M. Comsa, Krzysztof Potempa, Luca Versari +3
The timing of individual neuronal spikes is essential for biological brains to make fast responses to sensory stimuli. However, conventional artificial neural networks lack the int…
Randen - fast backtracking-resistant random generator with AES+Feistel+Reverie
Jan Wassenberg, Robert Obryk, Jyrki Alakuijala +1
Algorithms that rely on a pseudorandom number generator often lose their performance guarantees when adversaries can predict the behavior of the generator. To protect non-cryptogra…
Noise generation for compression algorithms
Renata Khasanova, Jan Wassenberg, Jyrki Alakuijala
In various Computer Vision and Signal Processing applications, noise is typically perceived as a drawback of the image capturing system that ought to be removed. We, on the other h…
Guetzli: Perceptually Guided JPEG Encoder
Jyrki Alakuijala, Robert Obryk, Ostap Stoliarchuk +3
Guetzli is a new JPEG encoder that aims to produce visually indistinguishable images at a lower bit-rate than other common JPEG encoders. It optimizes both the JPEG global quantiza…
