Imagine if you had built an artificial life simulator, and you sample a different neural network to control the behavior of each ant inside an ant colony. Using the Simple Evolution Strategy for this task will optimise for traits and behaviours that benefit individual ants, and with each successive generation, our population will be full of alpha ants who only care about their own well-being.A Visual Guide to Evolution Strategies
An unpredictable reward schedule is one of the basic mechanics in poker machines, and indeed many games. Because the time until a reward is given is uncertain, it keeps people interested in playing and therefore keeps them playing longer. Poker machine manufacturers refer to this as increasing the 'time on device'.Hooked: how pokies are designed to be addictive
When we train neural networks we usually use Gradient Descent to optimize the weights. At each iteration we use back-propagation to calculate the derivative of the loss function with respect to each weight and subtract it from that weight. Learning rate determines how quickly or how slowly you want to update your weight(parameter) values.Everything you need to know about Neural Networks
At Uber, event forecasting enables us to future-proof our services based on anticipated user demand. The goal is to accurately predict where, when, and how many ride requests Uber will receive at any given time.Engineering Extreme Event Forecasting at Uber with Recurrent Neural Networks
Using names of billionaires I created their Forbes profile URLs and collected the data I needed using RSelenium and rvest. I’ll be frank. It was not sexy at all. I did a lot of Excel VLOOKUPS, manual inspections and string manipulation to get a workable data set.A Data Driven Guide To Becoming a Consistent Billionaire
The first thing I tried was using an optical character recognition library called SwiftOCR. The problem with using SwiftOCR for my use case was that it is designed for reading strings (like giftcard codes) rather than individual numbers. I also couldn’t get it to differentiate between “this is an empty square” and “I couldn’t read this digit”. Behind the Magic: How we built the ARKit Sudoku Solver
