Arduino UNO R4: Empowering Machine Learning at the Edge for FIFA Match Predictions

Category articles

Microcontroller technology is constantly advancing, as evidenced by the new Arduino UNO R4. Based around Renesas RA4M1 microcontroller, this next-gen microcontroller takes great strides forward with upgrades in RAM, flash memory and CPU performance compared to its predecessor – UNO R3. These upgrades open up exciting opportunities such as running machine learning algorithms at the edge for inferencing of data streams; one individual who saw its potential was Roni Bandini who trained a model using his UNO R4 Minima to predict FIFA matches results using his UNO R4 Minima to predict FIFA matches outcomes using its RAM memory upgrades compared to predecessor – UNO R3.

Bandini began his project by collecting a massive dataset containing historical FIFA match data, such as participating countries, teams, opponents, rankings and whether matches were held at neutral locations. Armed with this wealth of information he integrated the dataset into Edge impulse – an innovative platform designed for developing and deploying machine learning models on edge devices – as a time series dataset, thus becoming training grounds for Keras classifier ML blocks within Edge impulse that would ultimately predict outcomes as either wins or draws in matches played over time. This combination would allow him to generate powerful predictions of match outcomes like “wins/draw” values or create valuable predictions of match outcomes by categorising match outcomes into “win/lose/draw” categories allowing him to accurately predict match outcomes using either “win/lose/draw” values

By engaging in intensive training sessions, this model achieved an outstanding accuracy rate of 69% – evidence of its ability to make reasonably accurate predictions. Furthermore, its loss value of 0.58 demonstrated its efficiency in understanding patterns and factors contributing to team’s success in FIFA matches.

Bandini integrated a DFRobot LCD shield into his setup to facilitate user interaction and input for predictions, making the selection of desired countries and ranks simple and user-friendly. Once selected values had been entered into the input tensor of his trained model, these values allowed it to be invoked and deliver classification results.

Bandini’s project stands as an impressive testament to the advanced capabilities of the Arduino UNO R4, in comparison with its predecessor, the R3. Boasting 16 times more RAM, 8 times flash memory and an increased processing power thanks to an exponentially faster CPU, the UNO R4 provides unparalleled processing power allowing for edge machine learning algorithms allowing real-time analysis and decision-making without external resources.

Applications for this sophisticated technology are many and varied, from predicting sports match outcomes to recognizing patterns across industries – the Arduino UNO R4 is an enabler of both developers and enthusiasts to harness machine learning at its edge. As it gains more momentum, we should expect more innovative projects using its power to meet future applications’ demands.

Running machine learning at the edge refers to deploying machine learning models directly on edge devices, such as microcontrollers or IoT devices, rather than using cloud servers for processing. This approach provides real-time data analysis without relying on constant connectivity with remote servers in the cloud.

To perform inferencing of data at the edge with machine learning, the Arduino UNO R4 microcontroller is utilized. Equipped with enhanced capabilities compared to its predecessor (UNO R3) such as increased RAM, flash memory, and faster CPU speed; this makes it capable of handling more complex computational tasks such as running machine learning algorithms.

Roni Bandini uses his Arduino UNO R4 Minima to train a model that predicts the likelihood of a FIFA team winning their match. To do this, he starts by downloading historical FIFA matches which contain details such as country, team name, opponent team name, rank order and neutral location information.

Edge impulse, a platform for creating and deploying machine learning models on edge devices, then integrates this dataset. It is formatted as a time series dataset before being fed to a Keras classifier – an artificial intelligence algorithm designed for classification tasks – for training on historical match data to learn patterns and make predictions.

Once trained, the model reached an accuracy of 69% with an overall loss value of 0.58. Bandini utilized a DFRobot LCD shield allowing user interaction with an Arduino UNO R4 to input country and rank predictions; once selected values are fed into input tensor of trained model, and invoked for classification by it.

Bandini showcased the increased processing power and capabilities of the Arduino UNO R4 by employing machine learning at its edge on it, which enabled real-time inferencing of incoming data for real-time analysis and decision making without using cloud resources.
