    Smartwatch Health Data Anomaly Detection

    Sold by: Mphasis 
    Deployed on AWS
    This solution uses an unsupervised anomaly detection approach to identify suspect health metrics in a person using their smartwatch data.

    Overview

    This solution utilizes unsupervised outlier detection methods to detect anomalous health events from multiple sensors providing their heart rate and steps data sequenced over a period of time. Such an approach does not require labelling, as the model learns to detect anomalous values from the provided distribution itself. This provides a convenient method for preemptive analysis making use of limited, relatively easily available data. The solution is meant to provide a quick risk assessment, and should not be used as a diagnostic test. If you believe you are ill, please get medical assistance.

    Highlights

    • In the case of unlabelled data in the healthcare domain, it is essential to be able to accurately diagnose, analyse and determine the problem at hand, despite the lack of labels for specific training. Multiple sources of data, such as heart rate and steps such as considered here, help with increasing the feature space for better model learning. An algorithm was devised to use the different types of together, and an outlier detection model is trained on the derived data values. This model allows us to robustly detect the presence of any outliers in the multimodal data.
    • This solution provides a way of preemptive evaluation given any patient's data. Detecting anomalous values with a high recall rate (minimum false negatives) which indicate the potential of the onset of a health event is quite useful as a precautionary diagnosis tool. While the final detection requires further medical tests, such solution helps identify candidates for further investigation

    Amazon SageMaker algorithm

    An Amazon SageMaker algorithm is a machine learning model that requires your training data to make predictions. Use the included training algorithm to generate your unique model artifact. Then deploy the model on Amazon SageMaker for real-time inference or batch processing. Amazon SageMaker is a fully managed platform for building, training, and deploying machine learning models at scale.

    Deploy the model on Amazon SageMaker AI using the following options:
    Before deploying the model, train it with your data using the algorithm training process. You're billed for software and SageMaker infrastructure costs only during training. Duration depends on the algorithm, instance type, and training data size. When training completes, the model artifacts save to your Amazon S3 bucket. These artifacts load into the model when you deploy for real-time inference or batch processing. For more information, see Use an Algorithm to Run a Training Job  .
    Deploy the model as an API endpoint for your applications. When you send data to the endpoint, SageMaker processes it and returns results by API response. The endpoint runs continuously until you delete it. You're billed for software and SageMaker infrastructure costs while the endpoint runs. AWS Marketplace models don't support Amazon SageMaker Asynchronous Inference. For more information, see Deploy models for real-time inference  .
    Deploy the model to process batches of data stored in Amazon Simple Storage Service (Amazon S3). SageMaker runs the job, processes your data, and returns results to Amazon S3. When complete, SageMaker stops the model. You're billed for software and SageMaker infrastructure costs only during the batch job. Duration depends on your model, instance type, and dataset size. AWS Marketplace models don't support Amazon SageMaker Asynchronous Inference. For more information, see Batch transform for inference with Amazon SageMaker AI  .
