  • Recent Reports Make Machine Learning Sound Like a Sport. It isn’t
    News that Baidu, the Google of China, cheated to take the lead in an international competition for artificial intelligence technology has caused a storm among computer science researchers. It has been called machine learning’s “first cheating scandal” by MIT Technology Review and Baidu is now barred from the competition...
  • Bayesian Dark Knowledge
    We consider the problem of Bayesian parameter estimation for deep neural networks, which is important in problem settings where we may have little data, and/ or where we need accurate posterior predictive densities, e.g., for applications involving bandits or active learning...
  • Kaggle Ensembling Guide
    Model ensembling is a very powerful technique to increase accuracy on a variety of ML tasks. In this article I will share my ensembling approaches for Kaggle Competitions...

  • Fast Lomb-Scargle Periodograms in Python
    The Lomb-Scargle periodogram is a classic method for finding periodicity in irregularly-sampled data. It is in many ways analogous to the more familiar Fourier Power Spectral Density (PSD) often used for detecting periodicity in regularly-sampled data. Despite the importance of this method, until recently there have not been any (in my opinion) solid implementations of the algorithm available for easy use in Python...

  • Signal: Understanding What Matters in a World of Noise

    New release!...

    "In Signal, I provide straightforward and practical instruction in everyday signal detection. Using data visualization methods, I teach how you can apply statistics to gain a comprehensive understanding of your data, which will serve as the context for signal detection. I then adapt the techniques of Statistical Process Control in new ways to detect not just changes in the measures but also significant changes in the patterns that characterize your data..."
