Passive-aggressive classifier for embedded devices

When working with memory constrained devices you may not able to keep all the training data in memory: passive-aggressive classifiers may help solve your memory problems.

How to train a IRIS classification Machine learning classifier directly on your Arduino board

In this hands-on guide about on-board SVM training we're going to see a classifier in action, training it on the Iris dataset and evaluating its performance.

So you want to train an ML classifier directly on an Arduino board?

As of now, we know it is possible to run Machine learning inference on tiny microcontrollers thanks to Tensorflow for Micro and my very own library MicroML. What if you could train a classifier directly on the microcontroller, too?

Handwritten digit classification with Arduino and MicroML

We continue exploring the endless possibilities on the MicroML (Machine Learning for Microcontrollers) framework on Arduino and ESP32 boards: in this post we're back to image classification. In particular, we'll distinguish handwritten digits using an ESP32 camera.

Even smaller Machine learning models for your MCU: up to -82% code size

So far we've used SVM (Support Vector Machine) as our main classifier to port a Machine learning model to a microcontroller: but recently I found an interesting alternative which could be waaaay smaller, mantaining a similar accuracy.

RVM vs SVM support vectors

Apple or Orange? Image recognition with ESP32 and Arduino

Do you have an ESP32 camera?

Want to do image recognition directly on your ESP32, without a PC?

In this post we'll look into a very basic image recognition task: distinguish apples from oranges with machine learning.

Word classification using Arduino and MicroML

In this Arduno Machine learning tutorial we're going to use a microphone to identify the word you speak.
This is going to run on an Arduino Nano (old generation), equipped with 32 kb of flash and only 2 kb of RAM.
