Classical AI

ADVANCED ARTIFICIAL INTELLIGENCE Syllabus Topic 1 Modern AI (5)

Classical AI • Machines will be capable of doing any work human can do.

ADVANCED ARTIFICIAL INTELLIGENCE Syllabus Topic 1 Modern AI (6)

Classical AI • The goal of classical AI was to explicitly represent human knowledge using facts and rules. • That is you program a machine with some rules and when you input a query, it gives the answer based on the rules. • Taking the example of the calculator, it is programmed with the rules of mathematical operations and when you input 2+3, it returns 5.

ADVANCED ARTIFICIAL INTELLIGENCE Syllabus Topic 1 Modern AI (7)

Classical AI • Classical AI worked very well in certain situation, but it still suffered from a major problem, that of rules. • What if there are lots of rules or if the rules are not well defined. • It becomes difficult to codify or specify the rules explicitly. • Example, if you want a machine to identify a cat, what rules would you specify to be able to identify it?

Modern AI (2008+) • Modern AI is capable to handle many of the weaknesses of classical AI. • Unlike classical AI, modern AI doesn’t need people to explicitly specify rules for it. • It is capable of learning rules on it own. • It can infer and extract the rules and patterns required to get from the input to the output.

ADVANCED ARTIFICIAL INTELLIGENCE Syllabus Topic 1 Modern AI (9)

Modern AI • Modern AI is in short a powerful method of pattern recognition and in many ways mimics how people learn. • Example, if you want a machine to be able to identify cats, you give it tons of cat pictures and have it understand what are the common features of cats. • Then whenever it sees another cat it is able to match its features and identify it as one.

ADVANCED ARTIFICIAL INTELLIGENCE Syllabus Topic 1 Modern AI (10)

Modern AI • The rise in modern AI can be attributed to three factors: ü Data Volume ü Statistical models ü Computing power

ADVANCED ARTIFICIAL INTELLIGENCE Syllabus Topic 1 Modern AI (11)

Modern AI • Data, and not just any volume of data but huge volume of data. • With a small volume of data, modern AI becomes very narrow. • You might have lots of data, and is extremely important for modern AI.

ADVANCED ARTIFICIAL INTELLIGENCE Syllabus Topic 1 Modern AI (12)

Modern AI • The rise in computing power due to better CPUs and GPUs means that the huge data volume aren’t simply stored in databases but can now be used. • This allows for applying new statistical models on the huge data volume using better computing resources to extract valuable information and patterns. • We can in short call this as Data Science.

ADVANCED ARTIFICIAL INTELLIGENCE Syllabus Topic 1 Modern AI (13)

Data Science • The term “Data science” was introduced in early 2008 by two data team leads from Linkedin & Facebook. (DJ Patel & Jeff Hammerbacher). • A look at the evolution of the data landscape, AI becomes the tool that helps data science get results and the solutions for specific problems.

How Data Science intersects the AI world? 14

ADVANCED ARTIFICIAL INTELLIGENCE Syllabus Topic 1 Modern AI (15)

Data Science vs. the world of AI • Some people say Data Science and Artificial Intelligence are synonyms. • Some say that one is a subset of the another and some say that these terms are completely unrelated.

ADVANCED ARTIFICIAL INTELLIGENCE Syllabus Topic 1 Modern AI (16)

AI - Data Science related terminology • Data Science and Artificial Intelligence typically have different objectives. • AI and Data Science overlaps at two cores of sub-knowledge, Data and Machine Learning. 16

What is Data Science? • Data Science is the science of collecting, storing, processing, describing and modelling data. 17

ADVANCED ARTIFICIAL INTELLIGENCE Syllabus Topic 1 Modern AI (18)

1. Collecting data • Collecting data depends on the question which is raised and the business environment. 18

ADVANCED ARTIFICIAL INTELLIGENCE Syllabus Topic 1 Modern AI (19)

Collecting data - Example 1 • Assume the data scientist is working for an e -commerce company. • A question the data scientist may be interested in, is Which items do customers buy? • Here the data already exists within the organisation and the data scientist must have knowledge of accessing the database using SQL etc. 19

ADVANCED ARTIFICIAL INTELLIGENCE Syllabus Topic 1 Modern AI (20)

Collecting data - Example 2 • Assume the Data scientist is working for a political party. A question the data scientist may be interested in, is What is people’s opinion about the new agenda of the party? • Here the data exists (in from of tweets, Facebook posts…) but not within the organisation. • So the data scientist must have web crawling (scraping) and other skills apart from programming skills. 20

ADVANCED ARTIFICIAL INTELLIGENCE Syllabus Topic 1 Modern AI (21)

Collecting data - Example 3 • Assume the Data scientist is working with farmers. • A question the data scientist may be interested in, is Effect of type of seed, fertiliser, irrigation on yield? • Here the data is not available and the data scientist needs to design experiments to collect data using Statistics etc. 21

ADVANCED ARTIFICIAL INTELLIGENCE Syllabus Topic 1 Modern AI (22)

Collecting data - Needed skills • Knowledge of Databases • Intermediate Programming • Knowledge of Statistics 22

ADVANCED ARTIFICIAL INTELLIGENCE Syllabus Topic 1 Modern AI (23)

2. Storing data • Data Warehouse ü used for analytical and reporting purposes. ü comes under OLAP (Online Analytical Processing). ü capable of both relational and multidimensional data. • Database ü used for transactional purposes. ü comes under OLTP (Online Transaction Processing). ü capable of storing relational data. 23
