  • Roman Roads
    It’s finally done. A subway-style diagram of the major Roman roads, based on the Empire of ca. 125 AD. Creating this required far more research than I had expected—there is not a single consistent source that was particularly good for this...

  • Work in progress: Portraits of Imaginary People
    For a while now I’ve been experimenting with ways to use generative neural nets to make portraits. Early experiments were based on deepdream-like approaches using backprop to the image but lately I’ve focused on GANs...
  • Self-Normalizing Neural Networks
    Deep Learning has revolutionized vision via convolutional neural networks (CNNs) and natural language processing via recurrent neural networks (RNNs). However, success stories of Deep Learning with standard feed-forward neural networks (FNNs) are rare. FNNs that perform well are typically shallow and, therefore cannot exploit many levels of abstract representations. We introduce self-normalizing neural networks (SNNs) to enable high-level abstract representations...
  • TextureGAN: Controlling Deep Image Synthesis with Texture Patches
    In this paper, we investigate deep image synthesis guided by sketch, color, and texture. Previous image synthesis methods can be controlled by sketch and color strokes but we are the first to examine texture control. We allow a user to place a texture patch on a sketch at arbitrary location and scale to control the desired output texture...


  • Data Scientist - FactSet - NYC

  • Visual Question Answering in Pytorch
    We developed this code in the frame of a research paper called MUTAN: Multimodal Tucker Fusion for VQA which is (as far as we know) the current state-of-the-art on the VQA-1 dataset...
  • Counting Objects with Faster R-CNN
    Below you can find a description of different approaches, common problems, challenges and latest solutions in the Neural Networks object counting field. As a proof of concept, existing model for Faster R-CNN network will be used to count objects on the street with video examples given at the end of the post....
  • Optimizing Python in the Real World: NumPy, Numba, and the NUFFT
    Too often, tutorials about optimizing Python use trivial or toy examples which may not map well to the real world. I've certainly been guilty of this myself. Here, I'm going to take a different route: in this post I will outline the process of understanding, implementing, and optimizing a non-trivial algorithm in Python, in this case the Non-uniform Fast Fourier Transform (NUFFT)...
