I got notified about Neuton AI, when Nordic Semiconductor acquired them last week. I have been playing around with the platform and the tools, and I am actually quite mind blown by what it can do.
Neuton is a no-code TinyML platform that builds ultra-compact neural-network models for small microcontrollers. You upload a CSV, press train & it grows the network, and you export it as a plain-C library that can be put on any microcontroller platform. The ridiculous part is the size of the generated model file is only around 5KB which is usually 10x lower than other ML platforms like TFlite, AutoKeras maintaining same or better accuracy. Small size also means inference time can be around 2ms. Faster inference implies lower battery usage too.
I really wanted to learn how they achieve this extreme size reduction. All the videos and content on the website are slightly vague. Their core tech is proprietary. Seems to have 2 US patents that cover architecture-free self-organisation and a parallel global search for weights and feature selection. What it means in practice is that the model stops growing the moment accuracy stalls, so there is nothing left to trim. They clearly mention they don’t use common training methods like back propagation or stochastic gradient descent. Each new neuron connects only to the most critical inputs or features rather than every possible input. This keeps the weight count low.
The platform keeps validation curves and lets you pick and download any smaller checkpoint if you prefer size to accuracy. It also has a signal processing engine to help with preprocessing of the data. Because the network connects only to the most informative inputs, it plays well with time series from IMUs, vibration sensors, ECG, and radar. I think this will let product teams skip a lot of manual DSPs and focus on features. Platform is also free to use, not sure if Nordic Semi fronting all the costs for the training runs.
For me personally, Neuton feels like a strong player for my future ML projects. Try it out yourself and see if it’s worth it for you.
