MarshallAI provides an Agile Focused Signal Analytics platform and end-user applications provided on it. MarshallAI is an end-to-end fully-fledged deep-learning platform for replication of human sensing. It has integrated tools for data acquisition, data annotation, model training, AI application (inference process) creation & management and result-data analysis & data forwarding. The platform can be operated via a web-GUI with an integrated visual programming system (VPS) or headless APIs. The system supports common computing platforms (x86, ARM, Windows, Linux) and can be run in its entirety on battery powered edge devices, as well as in data center scale setups. A key feature is the ability to utilise feedback loops for semi-unsupervised and active-learning methods.
