on a daily basis, so also the work that has to be done. • This has led to the increase of manpower in organizations, thereby reducing efficiency. • We can use Artificial Intelligence technologies to automate these routine labor, understand speech or image, make diagnosis in medicine thereby saving manpower as well as increasing productivity and efficiency. Artificial Intelligence - Why?
simply the science of getting the computer to learn without explicit programming. Machine Learning allows us to extract knowledge from data to form a prediction What is Machine Learning? 1 2
Artificial Intelligence can be used to build facial recognition system which are a viable option for authentication as well as identification. Chatbots • Many organizations embed AI chatbots on their websites to provide online customer care service/assistance.
its daily weather conditions. Diabetic Retinopathy • Artificial intelligence is also widely in healthcare. An example is predicting the different levels of diabetic retinopathy, an eye disease using images of the retina. Some Practical Applications of Machine Learning
that concerns systems of linear equations and their representations through matrices and vector spaces Numerical Computation This refers to algorithms that solve mathematical problems by methods that update estimates of the solution via an iterative process Probability & Statistics Probability is the measure of the likelihood that an event will occur in a Random Experiment. Essential Math for Machine Learning
• Image Processing • Image Classification • One - Hot Encoding • Natural Language Processing • Linear Regression • Recommenders Systems • Deep Learning • etc A B C D 1 0 0 1 1 0 1 1 0 1 0 0
Matrices and Tensors • Multiplying Matrices and vectors • Identity and Inverse Matrices • The Determinant • Linear Dependence and Span • Norms • Diagonal and Orthogonal Matrices • Eigen Decomposition • Singular Value Decomposition • Principal Component Analysis
framework for representing uncertain statements. Therefore; • The laws of probability tells us how AI systems should reason, so we design our algorithms to compute or approximate various expressions derived using probability theory. • We use probability and statistics to theoretically analyze the behaviour of proposed AI Systems
Machine Learning, our goal is to learn from labeled data. Data being labeled means that for some inputs X, we know the desired outputs Y • Some possible tasks are: - Identify what’s in an image - Predict the price of a stock given some features about the company - Detect if a file is malicious etc
together (clustering) • Taking high dimensional data and projecting it into a meaningful lower dimensional space • Representing data with a distribution • Reinforcement Learning; agents taking actions in their environment and observing reward signals based on their behavior.
finding the value of an argument that minimizes or maximizes a function • Evaluating a mathematical function on a digital computer can be difficult when the functions involves real numbers, which cannot be represented precisely using a finite amount of memory • The goal of Machine Learning model is to reduce the error that a certain prediction makes to get the highest possible accuracy from the model.
is capable of automating business intelligence and analytics processes, thereby providing end-to-end solutions. Fraud Detection • Companies like Teradata is an AI firm that sells fraud detection solution to banks. Their platform uses Machine Learning to enhance banking fraud detection. Online Customer Support • Companies like DigitalGenius is an AI-powered customer service tool that uses machine learning and natural language processing to completely automate the consumer support process
by enabling quick and cost-effective diagnosis of birth asphyxia from infant cry using machine learning system that can take as input the infant cry, analyse the amplitude and frequency patterns in the cry 18 Machine Learning in Business Cybersecurity Defense • Companies like DarkTrace are focused on using unsupervised Machine Learning to analyze network data at scale thereby responding to cyber threat somewhere in the world every 3 seconds
Company 1. Examine how your competitors are using AI e.g How are Hospitals using AI? How is Google using AI? etc 2. Decide what AI can do for your business 3. Search for and compare vendors 4. Implement an AI Project
value 1. Business Problem (Definition, value, stakeholders, priority, investment) - start small and narrow until you realize what the business value is 2. Data (Availability, provenance, security, coverage, cleaning, augmentation, annotation, refreshing, pipeline development) 3. Model Building (Feature extraction, hyperparameters, tuning, selection, benchmarking) 4. Deploy & Measure (Business value measurement, AB testing, versioning, business process integration) 5.
