Posit AI Weblog: AO, NAO, ENSO: A wavelet evaluation instance

Not too long ago, we confirmed find out how to use torch for wavelet evaluation. A member of the household of spectral evaluation strategies, wavelet evaluation bears some similarity to the Fourier Rework, and particularly, to its common two-dimensional utility, the spectrogram. As defined in that e book excerpt, although, there are important variations. For…

Posit AI Weblog: Implementing rotation equivariance: Group-equivariant CNN from scratch

Convolutional neural networks (CNNs) are nice – they’re in a position to detect options in a picture irrespective of the place. Properly, not precisely. They’re not detached to only any sort of motion. Shifting up or down, or left or proper, is okay; rotating round an axis will not be. That’s due to how convolution…

Posit AI Weblog: De-noising Diffusion with torch

A Preamble, kind of As we’re scripting this – it’s April, 2023 – it’s exhausting to overstate the eye going to, the hopes related to, and the fears surrounding deep-learning-powered picture and textual content technology. Impacts on society, politics, and human well-being deserve greater than a brief, dutiful paragraph. We thus defer acceptable therapy of…
