During development, IBM acquired a number of companies possessing large amounts of health data, but within four years, the project had been shut down at the M.D. IBM announced that they would build Watson for Health in 2013, launching services for cancer care that could recommend treatment regimens based on individual patient data and the latest research. Their later AlphaGo Zero algorithm, while not needing bootstrapping with even the rules of the game, or from records of previous games, benefitted from a novel approach to reinforcement learning in which it learnt outcomes from games it played against itself, generating data about outcomes in a feedback loop.īut what about machine learning and healthcare? Rather than simply applying a brute force, combinatorial approach to generate the best moves from a finite set of possible moves, the team used deep learning to create a continuously-learning algorithm that improved over time such learning provided human players with new insights into tactics and strategy as the algorithm used unconventional and unintuitive moves during its play. Google DeepMind’s AlphaGo took on and defeated one of the World champions of the game Go. As an adaptive algorithm tasked with optimising energy efficiency, the teams have demonstrated an improvement with performance improves over time, as a result of more data being available. After two years, with the benefit of real-world experience as well as a range of additional safety measures, the teams took the decision to make the system directly implement its recommendations. For example, in 2016, Google DeepMind built a automated recommendation algorithm to improve the energy efficiency of Google’s data centres the algorithm analyses data from thousands of sensors and is optimised to minimise energy consumption. Machine learning is already being used in fields outside of image and speech recognition. Modern advances in computationally-intensive methods, such as deep learning, enabled by advances in computing power, have resulted in widespread recent adoption in many domains such as image and speech recognition and excitement about its potential use in healthcare. Machine learning uses statistical methods to allow computers to learn from data in effect, an algorithm is generated by a computer based on data. building robust evaluation processes using a combination of synthetic, randomised controlled and real-life implementation phases.Īn algorithm is simply a list of rules to follow in order to solve a problem.structuring, generating and aggregating clinically meaningful clinical data, and,.developing expertise in data analytics and machine learning,.

I want to convince you that our use of machine learning in healthcare, building algorithms that learn for themselves, depends on:
