Comparing coordination models and architectures using embeddings

Marcello M. Bonsangue, Joost N. Kok, Gianluigi Zavattaro
2003 Science of Computer Programming  
We will use this notion to present equivalence and di erence results for several coordination models based on components that communicate either through an unordered broadcast, through an atomic broadcast  ...  The new notion, called architectural embedding, is suitable for the comparison of di erent communication mechanisms, and gives rise to a natural notion of implementability.  ...  This provides a useful framework for the relative comparison of coordination languages, models, and architectures; for example, it is possible to compare architectures in isolation, i.e., independently  ...

Image Generators with Conditionally-Independent Pixel Synthesis [article]

Ivan Anokhin, Kirill Demochkin, Taras Khakhulin, Gleb Sterkin, Victor Lempitsky, Denis Korzhenkov
2020 arXiv   pre-print
Here, we present a new architecture for image generators, where the color value at each pixel is computed independently given the value of a random latent vector and the coordinate of that pixel.  ...  We analyze the modeling capabilities of such generators when trained in an adversarial fashion, and observe the new generators to achieve similar generation quality to state-of-the-art convolutional generators  ...  To mine the most similar faces, we extract faces using the MTCNN model [33] , and then compute their embeddings using FaceNet [24] (the public implementation of these models 4 was used).  ...
