  17. The Interactive Data Explorer from pwc: https://www.pwc.com/gx/en/i ssues/data-and- analytics/publications/artificial -intelligence- study.html#explorer
  18. Neural Networks- crucial to development •“A Neural Network is a computer system designed to work by classifying information in the same way a human brain does. It can be taught to recognize, for example, images, and classify them according to elements they contain.”
  19. Interpretation of a neural network
  20. AI in (Old) Pop Culture • C-3PO • Skynet • Baymax • WOTAN (Doctor Who) • Omnius (Dune) • Cylons • Transformers • The Matrix
  21. AI vs. Machine Learning • AI is the broad category; machine learning is one application of AI • “AI is basically the intelligence – how we make machines intelligent, while machine learning is the implementation of the computer methods that support it.” For examples, if the category was pasta, tortellini would be one type of pasta.
  22. Machine Learning- definition • “Machine learning is an application of artificial intelligence (AI) that provides systems the ability to automatically learn and improve from experience without being explicitly programmed. Machine learning focuses on the development of computer programs that can access data and use it learn for themselves.” • *pattern recognition • ML is really “start of the art” of AI; true AI isn’t a reality yet
  23. Examples of Machine Learning • Virtual Personal Assistants- Siri, Alexis, Cortana • Traffic predictions • Surveillance systems • Computer vision à how Pinterest knows which pins to recommend • Facial recognition • Chatbots- Chatgpt, FB, Replika, Dadbot • Shopping recommendations (Alibaba)
  24. Examples of Machine Learning • Purchase predictions • Video games • Self-driving cars • Fraud detection • News generation • Pandora
  25. AI Industry Leaders
  26. Famous Real AI • Google Bard
  27. Let’s talk about Chatgpt… • What is it? • Chat Generative Pre-Trained Transformer is a Large Language Model (LLM) machine learning chatbot, created by AINOW and released in November 2022 • Why all the excitement? • Chatgpt is the first chatbot of its kind to be able to write and CONVERSE convincingly in English. • How is it being used in the sciences? • Write essays & talks • Summarize literature • Improve papers • Identify research gaps • Write computer code • Perform statistical analyses
  28. Chatgpt- on the positive side… • How might it revolutionize research practices? • Accelerate the innovation process • Shorten time-to-publication • Make science more equitable • Increase the diversity of science perspectives - From “ChatGPT: five priorities for research”
  29. Chatgpt, on the negative side… • Gets things wrong, spurring misinformation- and it’s very convincing • Needs to be carefully monitored/edited by a human subject matter expert • Its writings lack depth • It lacks its own set of ethics, relying on the sources from whom it learns to “create” them
  30. Chatgpt: an example from a friend: “write an incident report for an RA conducting rounds who identified a broken window”
  31. Examples of AI start-ups • Zipline- blood & vaccine delivery via drones • Everlaw- trial preparation through document analysis • Voicera- personal assistant • ShieldAI- drones in combat situations (mapping, identification)
  32. Why AI in healthcare? •Save time/efficiency •Shortage of clinicians •Improve patient outcomes
  33. Why AI in healthcare now? •The perfect storm •Tons of data ("big data") generated by the minute •Robust algorithms •Processing power
  34. Examples of AI in healthcare • Patient self-monitoring (builds on the “quantified self”) • Chronic and acute conditions; post-surgery • PeerWell- AI for total joint replacement • Patients begin using app before surgery. Patients receive customized daily lessons and tasks which require them to input their results directly into the app. Machine learning algorithm adjusts pre- and post-surgery instructions based on patient input. •Extended Visual Assistant (EVA) • Voice-controlled eyewear for the visually impaired • Uses machine learning to recognize objects, text, signs, etc, and verbally describes what it sees
  35. AI & Healthcare • Patient self-monitoring, cont • AI apps for more common ailments • Diabetes management • Palliative care • Congenital heart disease • Clinical trials • Finding the right candidates for trials • Predicting bioactivity of patients in trials • Scheduling • TrueCare’s Baymax bot • Finds a doctor for you and then schedules an appointment
  36. Examples of AI in Healthcare • Pattern recognition • Skin cancer detection • Arterys- AI assistant for radiologists (1st FDA approval) • Disease detection
  37. How AI in Predictive Analytics/Modelling can benefit patients • Increase the accuracy of diagnoses • Improve preventive medicine and public health • Enhance personalized care • Accurately predict insurance costs • Streamline research and development with prediction models • Guide drug development to deliver medications that meet public need • Better patient outcomes
  38. AI in Research •AIs can (and are!): • Analyze data • Clean data • Identify patterns in data • Discovery tools • Gather data; e.g.; drone operators in places that are too remote or dangerous for humans • Analyze & match data; e.g., matching patients to clinical trials
  39. Barriers to use of AI in healthcare •Dirty data (data management has to happen first) •Silo’d data •Discrimination •Patients can’t be adequately served if discriminated against
  40. Barriers to use of AI in healthcare •Lack of infrastructure/data management plan •DMP should be predicated on International Data Corporation (IDC) Third Platform Principles, which are anchored by 4 areas: •Big Data & Analytics •Cloud •Mobile •Social
  41. AI and Discrimination • AI is only as unbiased as: • the people who program it (mostly men; mostly white, in the US) • the data on which its trained • Deep neural networks for images most often trained on ImageNet, which is heavily biased towards white Westerners • Natural language processing algorithms trained on data sets scraped from GoogleImages, GoogleNews, and Wikipedia- all heavily influenced by men, which have led to misogynistic AIs • “… Amazon’s computer models were trained to vet applicants by observing patterns in resumes submitted to the company over a 10-year period. Most came from men, a reflection of male dominance across the tech industry.” – Amazon scraps secret AI recruiting tool that showed bias against women (2018) • the systems & institutions into which AI is deployed
  42. AI & Discrimination: Training Humans • “ first major photography exhibition devoted to training images: the collections of photos used by scientists to train artificial intelligence (AI) systems in how to ‘see’ and categorize the world.” • Explores two fundamental issues: • how humans are represented, interpreted and codified through training datasets • how technological systems harvest, label and use this material
  43. AI & Discrimination: Training Humans • Also of interest to the creators: • Affect-training recognition, a system used by AI in security & hiring systems, etc, to determine a person’s mental & emotional “aims to detect and classify emotions by analyzing any face” • ATR based on the work of Paul Ekman • From his website: “Dr. Ekman identified the six basic emotions as anger, surprise, disgust, enjoyment, fear, and sadness. His research shows the strongest evidence to date of a seventh emotion, which is contempt.” • Ekman’s work is highly disputed by other researchers in both the same and different fields.
  44. Affect- Training Recognition • Now ATR is being used in hiring, security, and other systems to determine whether someone would be a good employee or is a threat. • HireVu • “AI system to extract microexpressions, tone of voice, and other variables from video job interviews, which it used to compare job applicants against a company’s top performers.” • Emotient (Apple) • Claimed to be capable of identifying emotions from images of faces • Affectiva • detecting distracted and “risky” drivers on roads • measuring consumers’ emotional responses to advertising
  45. AI & Discrimination • ImageNet Roulette- And, surprise(!), AI has some pretty racist and misogynistic ideas about people. Or, rather, the dataset ImageNet Roulette draws from, ImageNet, is filled with problematic categories that reflect the bias often inherent in the large datasets that make machine learning possible. • ”Automated systems that replicate, and by extension exacerbate, the biases present in society have the power to codify those very problems.”
  46. Future applications of AI in healthcare • AI-powered predictive care • networked hospitals • better patient and staff experiences
