- 9. Artificial intelligence • What is 'Artificial Intelligence - AI' • Artificial intelligence (AI) = simulated intelligence in machines. • These machines are programmed to "think" like a human • mimic the way a person acts. • The ideal characteristic of artificial intelligence • ability to rationalize and take actions that have the best chance of achieving a specific goal • ** although the term can be applied to any machine that exhibits traits associated with a human mind, such as learning and solving problems. https://www.investopedia.com/terms/a/artificial-intelligence-ai.asp

- 21. Examples of projects • Big Data • Big data projects: • Fields: • “omics” data, human • gut microbiome sequencing, • social media, and • cardiac imaging • Too large and heterogeneous, and change too quickly, to be stored, analyzed, and used.

- 31. • “ … CAD system based on one of the most successful object detection frameworks, Faster R-CNN. The system detects and classifies malignant or benign lesions on a mammogram without any human intervention. The proposed method sets the state of the art classification performance on the public INbreast database, AUC = 0.95.”

- 33. • Deep learning architecture • To a clinically heterogeneous set of three-dimensional optical coherence tomography scans • Demonstrate performance in making a referral recommendation that reaches or exceeds that of experts on a range of sight-threatening retinal diseases after training on only 14,884 scans.
- 35. • Detecting lung nodules using deep learning. Tim Salimans, Open AI. • “Lung cancer is the leading cause of cancer-related death worldwide. • However, large-scale implementation of such screening programs requires radiologists to evaluate a huge number of scans, which is costly and error-prone. • Aidence is an Amsterdam start-up developing an AI assistant for helping radiologists with detecting, reporting and tracking of lung nodules. This talk covers the deep learning techniques that we use to obtain state of the art”
- 37. • “Streams, which was developed in partnership with technology company DeepMind, uses a range of test result data to identify which patients could be in danger of developing AKI and means doctors and nurses can respond in minutes rather than hours or days - potentially saving lives. More than 26 doctors and nurses at the Royal Free Hospital are now using Streams and each day it is alerting them to an average of 11 patients at risk of acute kidney injury.” https://www.royalfree.nhs.uk/news-media/news/new-app-helping-to-improve-patient-care/
- 40. • Algorithms have been developed to: • Take raw digital data output by the gamma camera • identify where the heart is, reconstruct it into tomographic images and re- orient those images • Take tomographic images of the heart • evaluate the signals from several hundred portions of the myocardium, comparing the strength of the signals with those expected in a normal heart and generate an exact quantitative measurement of the location, extent and severity of perfusion abnormalities of the heart. • Analyze the dynamic functioning of the heart (i.e., the way it contracts and thickens during its cycle). • A dynamic measurement of the heart cavity volume is performed from electrocardiographically gated three-dimensional nuclear cardiology images by automatically identifying the endocardial and epicardial surfaces and following their motion throughout the cardiac cycle.
- 42. • Despite their differences, EBM and ML can assist one another. • Algorithms can facilitate more precise estimates of individual risk, with implications for choice between diagnostic tests or therapies that can then be compared in prospective, adaptive, randomized controlled trials. • Mendelian randomization and statistical analyses based on directed acyclic graphs and different matching techniques. • validate causal inferences based on ML associations. • Clinical trials can compare ML-based interventions with usual care • to assess their feasibility and validity in routine care. • ML needs to develop common nomenclatures, evaluation and reporting standards, comparative analyses of different algorithms, and training programs for clinicians http://annals.org/aim/article-abstract/2680060/machine-learning-evidence-based-medicine
