I. Definition

● “The study and design of intelligent agents, where an intelligent agent is a system that perceives its environment and takes actions that maximize its chances of success.”

Russel and Norvig

● “Just as the Industrial Revolution freed up a lot of humanity from physical drudgery, I think AI has the potential to free up humanity from a lot of the mental drudgery.”

Andrew Ng

Definition

Thinking humanly Thinking rationally

“The exciting new effort to make computers think... machines with minds, in the full and literal sense.” (Haugeland, 1985)

“The study of mental faculties through the use of computational models.” (Charniak and McDermott, 1985

Acting humanly Acting rationally

“The study of how to make computers do things which, at the moment, people are better.” (Rich and Knight, 1991)

“Computational Intelligence is the study of the design of intelligent agents.” (Poole et al., 1998)

Definition● AI is a combination of:

○ Philosophy

○ Mathematics

○ Economics

○ Neuroscience

○ Psychology

○ Computer Engineering

○ Control theory and cybernetics

○ Linguistics

Robotic Process Automation (RPA)● High-Volume repeatable tasks

● Different from IT automation because adaptable

● “Just as the Industrial Revolution freed up a lot of

humanity from physical drudgery, I think AI has the

potential to free up humanity from a lot of the mental

drudgery.”

Andrew Ng

Machine Learning● Computer to act without programing

● Deep learning: automation of predictive analytics

● Three types:

○ Supervised learning

○ Unsupervised learning

○ Reinforcement learning

● Good read on current unefficiency of ML:

ng

○ Some “old” AI algorithms are very good and suffice most

applications (“linear/logistic regression, random forests and boosted decision trees”)

○ Deep Neural Networks is the real (“Getting deep learning to work is hard “)

Machine Learning● Supervised learning

○ Sets are labeled → pattern detection → label new data sets

● Unsupervised learning○ Unlabelled sets sortes according to = or ≠

● Reinforcement learning○ Markov decision process - good for processes that

include long-term versus short-term reward trade-off (agent performs action(s) and is given feedback) - AlphaGo

Computer Vision ● Analog-to-digital signal processing

● Compares digital processing to database

● YOLO (You Only Look Once) open source real-time

object detection

arns_to_recognize_objects_instantly/up-next

○ 20ms/image

● Google Image, self-driving cars ...

Natural Language Processing

● Processing of human language by a computer program

● Used very early in spam detection

● Current approach is based on machine learning

Deep Neural Networks

● Algorithms designed after human brain ● Recognise patterns● “Clustering and classification data on top of data you

store and manage”1

● Help group unclassified data ● Classify when given labelled data to train on● “Deep” ⇔ stacked neural networks (multiple layers,

more than one hidden layer)○ Layers are made of nodes

Deep Neural Networks

● Deeper the net, more complex features can nodes recognize = feature hierarchy

● Google photos, Salesforce Einstein● Three steps to neural networks

○ scoring input, calculating loss and applying an update to the model

Starts with linear regression model for binary output but used logistic regression (sigmoïds, Hyperbolic tangents)

Deep Neural Networks

● 1957: Rosenblatt’s perceptron - 1st artificial neuron● 1969: Minsky’s doubts● 1989: LeCun proposes convoluted network ● 1996: Banks start using them for cheque reading● 2011: Watson wins Jeopardy● 2012: 15.3% error percentage ● 2016: Uber’s autonomous vehicles in Pittsburgh● 2017: Alpha Go beats Ke Jie

II. Issues

Prediction

● Predictive recommendation

● To simplify:

○ Consider all past events occurred at random

○ Group your data

○ Find a mathematical model that suits best

○ Iterate

Smarter objects

● Smart Home

○ Smart fridge

■ Samsung FamilyHub fridge (You can go

have a look at it at Boulanger down the street)

○ Apple HomePod, Amazon Alexa, Google

Home, Nest etc.

○ iRobot vacuum cleaner

Self-driving (cars?)

● Computer Vision

● Behavioural Prediction

● Influential companies include:

○ Waymo

○ Apple

○ Mobileye

○ Uber

○ Tesla

Level Name 0 No Driving Automation 1 Driver Assistance 2 Partial Driving Automation 3 Conditional Driving Automation 4 High Driving Automation 5 Full Driving Automation

(Chat)bots

● Human agent interaction platform

● Can be included in ready existing chats

● Or embedded in a website

● Most common uses:

○ Personalised customer experience

○ Virtual Buying assistant

○ Included in a CRM

○ News

○ Productivity tools (slack bots)

Chatbots● A few useful links:

○ Designing a chatbot (no coding)
