Normalizing Flows: An Introduction and Review of Current Methods

WebThe idea to model a normalizing flow as a time one map y = f (z) = Φ1(z) was presented by [chen2024neural] under the name Neural ODE (NODE) . From the deep learning perspective this can be seen as an “infinitely deep” neural network with the input layer z, the output layer y and continuous weights θ(t). Web6 de out. de 2024 · To this end, we propose a novel fully convolutional cross-scale normalizing flow (CS-Flow) that jointly processes multiple feature maps of different scales. Using normalizing flows to assign meaningful likelihoods to input samples allows for efficient defect detection on image-level. Moreover, due to the preserved spatial … slow cooker ribs 2 https://northernrag.com
