  • Philips Sonicare – A smart toothbrush that uses AI to analyze the brushing behavior and oral health of users, and provide real-time guidance and personalized recommendations, such as optimal brushing time, pressure, and coverage, to improve their dental hygiene and prevent cavities and gum diseases.

For many years, Philips has been pioneering the development of data-driven algorithms to fuel its innovative solutions across the healthcare continuum. In the diagnostic imaging domain, Philips developed a multitude of ML applications for medical image reconstruction and interpretation, workflow management, and treatment optimization. Also in patient monitoring, image guided therapy, ultrasound and personal health teams have been creating ML algorithms and applications. However, innovation was hampered due to using fragmented AI development environments across teams. These environments ranged from individual laptops and desktops to diverse on-premises computational clusters and cloud-based infrastructure. This heterogeneity initially enabled different teams to move fast in their early AI development efforts, but is now holding back opportunities to scale and improve efficiency of our AI development processes.

It was evident that a fundamental shift towards a unified and standardized environment was imperative to truly unleash the potential of data-driven endeavors at Philips.

Key AI/ML use cases and platform requirements

AI/ML-enabled propositions can transform healthcare by automating administrative tasks done by clinicians. For example:

  • AI can analyze medical images to help radiologists diagnose diseases faster and more accurately
  • AI can predict future medical events by analyzing patient data and improving proactive care
  • AI can recommend personalized treatment tailored to patients’ needs
  • AI can extract and structure information from clinical notes to make record-taking more efficient
  • AI interfaces can provide patient support for queries, reminders, and symptom checkers

Overall, AI/ML promises reduced human error, time and cost savings, optimized patient experiences, and timely, personalized interventions.

One of the key requirements for the ML development and deployment platform was the ability of the platform to support the continuous iterative development and deployment process, as shown in the following figure.

The AI asset development starts in a lab environment, where the data is collected and curated, and then the models are trained and validated. When the model is ready and approved for use, it’s deployed into the real-world production systems. Once deployed, model performance is continuously monitored. The real-world performance and feedback are eventually used for further model improvements with full automation of the model training and deployment.

The more detailed AI ToolSuite requirements were driven by three example use cases:

  • Develop a computer vision application aimed at object detection at the edge. The data science team expected an AI-based automated image annotation workflow to speed up a time-consuming labeling process.
  • Enable a data science team to manage a family of classic ML models for benchmarking statistics across multiple medical units. The project required automation of model deployment, experiment tracking, model monitoring, and more control over the entire process end to end both for auditing and retraining in the future.
  • Improve the quality and time to market for deep learning models in diagnostic medical imaging. The existing computing infrastructure didn’t allow for running many experiments in parallel, which delayed model development. Also, for regulatory purposes, it’s necessary to enable full reproducibility of model training for several years.

Non-functional requirements

Building a scalable and robust AI/ML platform requires careful consideration of non-functional requirements. These requirements go beyond the specific functionalities of the platform and focus on ensuring the following:
