Summary

Planning a workout that meets a user’s specific needs can be challenging. Researchers at the University of California, San Diego, have developed a deep learning-based system to better estimate a runner’s heart rate during a workout and predict a recommended route. This system, named FitRec-Attn, uses a Long Short Term Memory (LSTM) based model trained on a dataset of over 250,000 workout records from more than 1,000 runners. The model can predict the speed and heart rate on a specific future workout time and routes, and even recommend alternate routes for users working towards a specific heart rate.

Personalized Workout Recommendations with AI

The Challenge of Tailored Workouts

Creating a workout plan that is tailored to an individual’s needs can be difficult. Traditional methods often rely on general guidelines and do not account for the unique characteristics and goals of each user. This can lead to ineffective workouts and a lack of motivation.

Introducing FitRec-Attn

FitRec-Attn is a deep learning-based system designed to provide personalized workout recommendations. Developed by researchers at the University of California, San Diego, this system uses a Long Short Term Memory (LSTM) based model to predict a runner’s heart rate during a workout and recommend a suitable route.

How FitRec-Attn Works

FitRec-Attn was trained on a dataset of over 250,000 workout records from more than 1,000 runners. The model uses this data to learn embedded representations from auxiliary information such as user identity, sport type, and historical workout sequences. This information is then used to predict the speed and heart rate on a specific future workout time and routes.

Key Features of FitRec-Attn

  • Heart Rate Prediction: FitRec-Attn can accurately predict a runner’s heart rate during a workout, allowing for more effective planning and monitoring.
  • Route Recommendation: The system can recommend routes based on the user’s goals and preferences, including alternate routes for users working towards a specific heart rate.
  • Personalization: FitRec-Attn provides personalized recommendations based on the user’s unique characteristics and workout history.

Training and Testing

FitRec-Attn was trained using NVIDIA GeForce GTX 1080 TI GPUs with the cuDNN-accelerated PyTorch and TensorFlow deep learning frameworks. The model was tested against three other models, including Windows MLP, Seq2Seq, and DA-RNN, and was found to outperform all of them.

Potential Applications

FitRec-Attn has the potential to improve fitness tracking apps and devices by providing more accurate and personalized workout recommendations. The system could also be used to help users achieve specific fitness goals, such as training for a marathon or improving cardiovascular health.

Future Developments

While FitRec-Attn is still a proof of concept, the researchers hope to make the system available in commercial fitness apps in the future. The dataset and corresponding code used in this work will be released to the public, allowing other researchers and developers to build upon this technology.
