Confidence Values If you’ve ever learned any basic statistics or probability then you’ve probably encountered the 68-95-99.7 rule at some point. This rule is simply the statement that, for a normally distributed variable, roughly 68% of values will fall within one standard deviation of the mean, 95% of values within two standard deviations, and 99.7% within three standard deviations. These confidence values are quite useful to memorize because values that are computed from data are often approximately normally distributed due to the central limit theorem.

A Bug on Linux? Why, I never! I’ve been using GNU/Linux for about fifteen years and, I’ve got to admit, it used to be pretty rough around the edges (to put it lightly). A lot can change over fifteen years though; most of the things that were once major problem areas haven’t required a second thought in years. Laptop suspension, WIFI, advanced function keys, sound, and pretty much everything else all typically “just work” these days, and this has been the case for quite a while.
Choosing Weights: Small Changes, Big Differences There are a number of important, and sometimes subtle, choices that need to be made when building and training a neural network. You have to decide which loss function to use, how many layers to have, what stride and kernel size to use for each convolution layer, which optimization algorithm is best suited for the network, etc. With so many things that need to be decided, the choice of initial weights may, at first glance, seem like just another relatively minor pre-training detail, but weight initialization can actually have a profound impact on both the convergence rate and final quality of a network.
Intoli is Joining the NVIDIA Family We’re very pleased to announce today that Intoli will officially be joining the NVIDIA Inception Program for exceptional technology startups who are revolutionizing their industries with advances in artificial intelligence (AI) and data science. NVIDIA has been instrumental in the resurgence of neural networks in machine learning over the last several years. The rise of GPU-accelerated neural network training has allowed for major advances in the field of deep learning and NVIDIA’s GPU lines, Deep Learning SDK, and investment in AI startups have all undoubtedly played an immense role in that.
Update: This article is regularly updated in order to accurately reflect improvements in Firefox’s headless browsing capabilities. Note: Check out Running Selenium with Healdess Chrome if you’d rather use Google’s browser. Using Selenium with Headless Firefox (on Windows) Ever since Chrome implemented headless browsing support back in April, the other major browsers started following suit. In particular, Mozilla has since then expanded support for Firefox’s headless mode from Linux to its Windows and macOS builds, and fixed a number of bugs that might have been in the way of early adopters.
Introduction I’ve been doing a lot of technical writing recently and, with that experience, I’ve grown to more deeply appreciate the writing of others. It’s easy to take the effort behind an article for granted when you’ve grown accustomed to there being new high-quality content posted every day on Hacker News and Twitter. The truth is that a really good article can take days or more to put together and it isn’t easy to write even one article that really takes off, let alone a steady stream of them.
Introduction Over the years, I’ve collected a handful of videos that I deeply enjoy and that have had a significant impact on me as a developer. These are videos that I love introducing people to and I’m happy to have the chance to share them with you here. I find them all inspirational in their own ways and they serve as a continuous reminder for me to keep an open mind and to take creative approaches to problems.
