Algorithmic Intuition is focused on technology that gives devices the ability to better understand people and what they are doing. Combining small sensors with advanced algorithms, devices can compute and identify human activity and context. It is only in the past few years that we have seen the convergence of small, low-cost, low-power sensors with advanced machine-learning ("AI") algorithms and light-weight communications technologies. Taken together these advancements open broad new applications for activity recognition that were previously impossible.
Sensor Fusion is the synergy accomplished by combining several sensors to yield a result greater than the sum of the parts. Properly chosen sensors can help compensate for errors, reduce cross-terms and can provide calibration metrics to keep other sensors more accurate. Sensor Fusion was first developed for Inertial Navigation Systems where accelerometers, gyroscope and magnetometers measurements were fused to compute position and attitude. Today, sensor fusion algorithms are critical components of most consumer products, including automobiles (with 100+ sensors), mobile phones (25+ sensors), house hold applianced and Internet of Things.
Machine learning is when computer algorithms are trained on vast sets of data and taught to recognize patterns. This is different from traditional programming where humans are tasked with painstakingly searching for these patterns, often with smaller data sets. Now in a world awash in data, richer and more subtle patterns can be found. With increasing advances in Machine Learning algorithms, such as Deep Neural Networks (DNNs; which attempt to emulate the way the brain works), we are find impossible problems (speech recognition, language translation, etc) to be merely difficult problems. We are applying these advances to the challenges of Human Activity Recognition.
Wearables & Wireless
As sensors keep getting smaller and microelectronics shrink, we can now monitor our activity in ever more precise ways. From tracking our steps, movement, activity and sleep (to name a few), to understanding our heart rate, breathing, blood chemistry and more. These given us a deeper understanding of ourselves. To get these answers we need sensors that go with us and that don't tether us with wires. New technologies are giving us tiny sensors that can go with us day after day and let us leave the wires at home.
