Completed ZeroSensors all ready for long term data collection

Finally this is a ZeroSensor all ready to go into full time service, capturing video, audio and environmental data. The goal is to use this data, and that from other cameras around the space, as training data for machine learning systems.

One specific goal is to create an anomaly detector with minimal supervision. As much as possible, it will learn from experience. This is kind of tricky as it requires detection of unknown length sequences depending on the circumstances. I am intrigued by the ideas behind the Universal Translator but not sure how much could carry over to this application. This paper reviews some of the techniques usually applied, at least for video processing. The situation here is a little different as there are quite different types of features involved. My plan is to preprocess video and audio to recognize salient features (using object detection or whatever) and then input these features, along with environmental sensor data, in the form of uniform time-slotted data sets to the anomaly detector. This doesn’t help with detecting the length of an interesting sequence – that’s the fun part of the project.
