Run or Walk (Part 2): Collecting Device Motion Data the Right Way

Read previous part: “Run or Walk (Part 1): Detecting Motion Data Activity with Machine Learning and Core ML” Being motivated to develop a machine learning model that accurately predicts whether the user walks or runs, I needed data. A quick search for the publicly available datasets which contain such activities…

Run or Walk (Part 1): Detecting Motion Activity with Machine Learning and Core ML

There were a lot of announcements during recent Apple WWDC conference in June. One of the most remarkable is the release of Core ML framework that provides on-device machine learning capabilities to every developer. And this is revolutionary. Revolutionary means that earlier, the one who wanted to use any somewhat…
