Thoughts on Artificial Intelligence in Health


Thoughts on Artificial Intelligence in Health (last updated 27 Feb 2016)

Key points:

  1. Current edge in AI is self-teaching systems
  2. Data scientists offer a unique edge to information-dense, complex systems - make better decisions in the oncoming period of disruption.
  3. The use of AI in Healthcare will aim to reduce the downside of the critical human element (eg fatigue, mistakes, gaps in knowledge) and augment the benefits (more patient-doctor time, comprehension / observation of complex emotional situations, comfort, human touch and compassion)

Latest News:


  1. 26 Feb 2016: Google AI group, DeepMind, launches DeepMind Health with two initial apps: Streams, to find patients at high risk of acute kidney injury; Hark, to manage clinical tasks and interventions. Here's Imperial College London's experience with Hark.
  2. Artificial intelligence startup MedyMatch launches, former Philips exec tapped as CEO


Current Weaknesses in the System


  1. Dependent on the accuracy of structured data
  2. Ability to interpret unstructured data still rapidly developing
  3. Disease is multifactorial - and treatment success is in part driven by patient compliance (human factor again)





Artificial Intelligence and its Impact on Health


The aim of this post is to capture some static points on AI, catch up myself and readers on AI's history, definitions and touchpoints. Also cos the original post was getting super long.

For the latest updates and more interpretative components, you should read this post.


Where AI was
Here's a great article summarising the key milestones of AI and predicting where the technology is trending.

This was a particularly seminal moment: "In 2011, IBM's AI system, dubbed "Watson," won a game of Jeopardy against the top two all-time champions" but it wasn't til I played with Google Photos on a walk through Hobart that I realised this amazing potential spanned data in all its forms - not just words, but images, sound, light...

A Rose by any other name
Business Intelligence, Data Mining, Sensing, Pervasiveness, Ubiquity and Intelligent Agent

... essentially, data gathering + pattern recognition + prediction + learning / modifying rules = AI

AI in Health

From the 2015 EPIA conference in Coimbra, the organisers provided an overview of the expansive range of topics that fall under the AI banner, loosely:

Medical methodologies, architectures, environments and systems:

Agents for information retrieval;
AI in Medical Education and Clinical Management;
Wellbeing and lifestyle support;
Interoperability, Security, Pervasiveness, Ubiquity and Cloud Computing in Medicine;
Methodological, philosophical, ethical, and social issues of AI in Medicine;
Pervasive Healthcare Environments;
Software architectures.

Knowledge engineering and Decision Support Systems:

AI-based clinical decision making and Clinical Decision Support Systems;
Automated reasoning, Case-Based Reasoning or Reasoning with medical knowledge;
Business Intelligence in Health Care;
Clinical Data Mining;
Data Streaming;
Diagnostic assistance;
Expert, agent-based or knowledge-based systems;
Medical knowledge engineering;
Pervasive or Real-Time Intelligent Decision Support Systems in Critical Health Care.

Medical Applications and Devices:

Computational intelligence in bio- and clinical medicine;
Electronic Health Records (eHealth);
Image recognition and interpretation;
Intelligent devices and instruments;
Sensor-based applications;
Telemedicine and mHealth solutions;
Ubiquitous devices in the storage, update, and transmission of patient data;
Usability and acceptability.

AI in Healthcare Information Systems:

Autonomous systems to support independent living;
Healthcare System Based on Cloud Computing;
Intelligent Healthcare information systems;
Pervasive Information Systems;
Pervasiveness and Security in Clinical Systems;
Smart homes, hospitals and Intelligent Systems;
Simulation Computer systems.

Essentially: ... data drives decisions in large complex systems, and that's not a bad thing. Dan Sullivan from Strategic Coach, in a podcast on healthcare and education, observed: "to the degree that hospitals have data scientists, those are the ones that will have great breakthroughs".

What is the impact of that?
The human element is a strength and a weakness - so the use of AI will aim to reduce the downside of that (eg fatigue, mistakes, gaps in knowledge) and augment the benefits (more patient-doctor time, comprehension / observation of complex emotional situations, comfort, human touch and compassion).

See Fastcompany's assessment on how AI will fit into the hospital workflow:

"Robots won't steal doctors' jobs, says [Venkat] Rajan, but they will spare overworked docs some of the dangerous fatigue that can lead to mistakes. "They're stressed, they’ve got a million different things they're looking at, so [there's] stuff they might have missed."

*Venkat Rajan, Global Director, Visionary Healthcare program, at Frost & Sullivan.

Hope and Future Nanotechnologies

"A Leader is a dealer in Hope" - Napoleon Bonaparte.

(... Notice it doesn't say *false* hope.)

This year at the Abundance 360 summit, I had the distinct delight of meeting Ray Kurzweil.


Described as the "rightful heir to Thomas Edison", and a prediction success rate of 86%, Mr Kurzweil's predictions about the future of human consciousness are:
  • in 2029 (or well, 2045), we will reach the singularity
  • in 2030, human brains will be able to connect to the cloud, allowing us to send emails and photos directly to the brain and to back up our thoughts and memories - via nanorobots
(The singularity is Mr Kurzweil's prediction of a point in time when improvements in artificial intelligence generates an intelligence explosion and surpasses human intelligence. Read more: Wikipedia and Kurzweil.AI)

Imagine what this means for the capacity of cognition, emotion, engagement, experiences... the presence and management of mental health conditions, intellectual pursuits and physical endeavours?

Read more: coverage on Huffington Post and Ray Kurzweil's talk on TED.

Neuro nanorobotics. The idea itself is appealing... to reach the corners of the human mind that have been hard to sweep clean, to scratch the itch that lies beyond the blood-brain barrier.

It is the ultimate in personalised medicine: robots derived from and integrating with your own DNA strands... Add to the trend of shrinking the size of technology and you have your own diagnostic, investigative and therapeutic agent swimming around your bloodstream.

Even better than that, according to Mr Kurzweil, is the augmentation of thought: the hybridisation of logical and emotional intelligence. Expansion of physical or quantitative (read: sheer volume) of the brain will lead to a qualitative leap in culture and technology. Want proof? We did it before - humans have a frontal cortex and our primate cousins do not.

Fortunately, we've got 14 years to get there.

And his answer to my question: "Where could I join the nanorobotics revolution?" (after all, it is the ultimate in personalised patient-centric medicine (hence my fascination): robots derived from and integrating with your own DNA strands...)

With a smile he said, "Why don't you apply to Singularity University?". :)


What are your suggestions? Where is the edge of neurorobotics research and who (or which institute) leads the field?
