CanvasGAN: A simple baseline for text to image generation by incrementally patching a canvas
We propose a new recurrent generative model for generating images from text
captions while attending on specific parts of text captions. Our model creates
images by incrementally adding patches on a "canvas" while attending on words
from text caption at each timestep. Finally, the canvas is passed through an
upscaling network to generate images. We also introduce a new method for
generating visual-semantic sentence embeddings based on self-attention over
text. We compare our model's generated images with those generated Reed et.
al.'s model and show that our model is a stronger baseline for text to image
generation tasks.Comment: CVC 201
Isotropization and hydrodynamization in weakly coupled heavy-ion collisions
We numerically solve 2+1D effective kinetic theory of weak coupling QCD under
longitudinal expansion relevant for early stages of heavy-ion collisions. We
find agreement with viscous hydrodynamics and classical Yang-Mills simulations
in the regimes where they are applicable. By choosing initial conditions that
are motivated by color-glass-condensate framework we find that for Q=2GeV and
=0.3 the system is approximately described by viscous hydrodynamics
well before fm/c.Comment: 6 pages, 4 figures. Shortened for PRL, figs. 1 and 2 modifie
