Syllabus for Class 9 AI Olympiad
1. INTRODUCTION TO AI
Algorithms always cast a spell on enthusiastic minds. The mystery behind solving complex work through codes fascinates us. Intrigued by how circuits built by engineers can think and work with minimum human intervention, human beings are easily drawn into technology and its innovations. In the domain of Computer Science, Artificial Intelligence, sometimes called machine intelligence, is intelligence demonstrated by machines that stands in contrast to the natural intelligence exhibited by humans.
Data and algorithms rule the world by providing better and rapid information about the future. Everyone of us is drawn to the ineffable capacity of algorithms that creates more and more data and can program and optimize themselves. To build a rock-solid competence in computing, it is imperative to upgrade our skills and keep going with the flow.
The term “Artificial Intelligence” is used to describe any time a computer does something that would require the intelligence of a human — or anything that mimics human intelligence, whichever way you want to think of it.
AI in marketing is already widespread, and you probably interact with AI on a daily basis. Here are some ways you interact with artificial intelligence:
1. Search engines like Google use AI (algorithms like Rankbrain) to determine the most appropriate result for a search.
2. Automated marketing emails use AI to figure out what emails to send based on how you’ve interacted with a business or website.
3. Various types of online ads use AI to determine who should see a specific ad, based on past behavior, interests and search queries.
4. Chatbots are becoming more common in online messengers so that larger brands can assist customers immediately and efficiently.
A bot is a computer program that is designed to communicate with human users through the internet. It allows a form of interaction between a human and a machine the communication, which happens via messages or voice command. A chatbot is programmed to work independently from a human operator.
5. Voice searches on smart speakers or even smartphones use AI to determine the best result for those long-tail keywords and conversational queries.
- Artificial Intelligence: HISTORY
The advent of modern AI can be traced back to the experiments of classical philosophers that attempt to describe human thinking as a symbolic system. However, the term “artificial intelligence” was first coined during a conference at Dartmouth College, in Hanover, New Hampshire in 1956.
- Artificial Intelligence: NEED
Artificial intelligence uses machine learning to mimic human intelligence. The computer has to learn how to respond to certain actions, so it uses algorithms and historical data to create something called a propensity model.
Propensity models will then start making predictions (like scoring leads or something).
AI can do much more than this, but those are common uses and functionality for marketing. And while it might seem like the machines are ready to rise up and take over, human interventions are still needed to do much of the work.
Mainly, we use AI to save time — adding people to email automation and allowing AI to do much of the work while we work on other tasks.
- Artificial Intelligence: PURPOSE
Having good basics in mathematics along with coding skills help understand the working of the machine learning models. Artificial intelligence (AI) is the simulation of human intelligence processes by machines, especially computer systems. These processes include learning (the acquisition of information and rules for using the information), reasoning (using rules to reach approximate or definite conclusions) and self-correction.
- Artificial Intelligence: POSSIBILITIES
We are in a relentless effort to explore the unfathomable ocean of technology. Every facet of business has become completely digitised. There is a constant drive towards innovation and new technological models that will help humanity evolve, and become better. Buzzwords like AI, automation and quantum technology are trending in social media.
- Artificial Intelligence: ETHICS
Ethics refers to the branch of philosophy concerned with grounding decisions, beliefs, policies, etc. in some sort of framework for deciding right and wrong. Ethics takes into account the questions related to human morality and tries to resolve them through discussions and debates. By deriving some moral system, we can prescribe value to some action or belief.
There are some main areas of study in ethics that can be further broken into subcategories:
1. Applied Ethics — concerned with studying what is right or just and what is valuable.
2. Normative Ethics — study of how people should/ought act
3. Meta-ethics — pursuit of understanding what is good or bad, what do these concepts of good/bad really mean?
2. AI PROJECT CYCLE
The machine learning life cycle refers to the cyclical process that data science projects follow. It defines each step that an organization should follow to take advantage of machine learning and artificial intelligence (AI) to derive practical business value.
- PROBLEM SCOPING
The ultimate goal of artificial intelligence is to create computer programs that can solve problems and achieve goals like human beings could. There is immense scope in developing machines in robotics, computer vision, language detection machine, game playing, expert systems, speech recognition machine and much more.
- DATA ACQUISITION
Data acquisition is the process of measuring physical world conditions and phenomena such as electricity, sound, temperature and pressure. This is done through the use of various sensors which sample the environment’s analog signals and transform them to digital signals using an analog-to-digital converter.
Data acquisition plays a critical role in various fields such as life science research, civil engineering and industrial maintenance, to name a few. On walking into any steel mill, public utility or research laboratory in the world, you are sure to find some sort of data acquisition device, quietly monitoring one parameter or another. The data gathered can be used to enhance efficiency, ensure reliability or to make certain that machinery is operating safely. Recorded data is retrieved to ensure that the system under test performed as expected, and to identify problem areas that need adjustments. Real time data acquisition systems generate and display measurements without delay.
- DATA EXPLORATION
Data Exploration is an approach similar to initial data analysis, whereby a data analyst uses visual exploration to understand what is in a dataset and the characteristics of the data. Actually, it is an initial data analysis. Exploration precedes any statistical analysis and machine learning model.
- DATA MODELING
Data modeling in software engineering is the process of creating a data model for an information system by applying certain formal techniques.
3. NEURAL NETWORK
A neural network is either a system software or hardware that works similar to the tasks performed by neurons of human brain. Neural networks include various technologies like deep learning, and machine learning as a part of Artificial Intelligence (AI).Olympiad Exam for Class 9
Artificial neural networks (ANN) is the key tool of machine learning. These are systems developed by the inspiration of neuron functionality in the brain, which will replicate the way human beings learn. Neural networks (NN) constitute both the input & output layer, as well as a hidden layer containing units that change input into the output so that the output layer can utilise the value. These are the tools for finding patterns that are numerous & complex for programmers to retrieve and train the machine to recognize the patterns.
- FUNCTION OF NEURAL NETWORK
Neural Networks are considered Universal Function Approximators. It means that they can compute and learn any function at all. Almost any process we can think of can be represented as a functional computation in Neural Networks.
Neural networks have a remarkable ability to retrieve meaningful data from imprecise data, that is used in detecting trends and extracting patterns that are difficult to understand either by computer or humans. A trained NN can be made an “expert” in the information that has been given to analyse and can be used for providing projections. Olympiad Exam for Class 9
Python is an interpreted, high-level, general-purpose programming language. Created by Guido van Rossum and first released in 1991, Python’s design philosophy emphasizes code readability with its notable use of significant whitespace.
- PYTHON – VARIABLE
Python is dynamically typed, which means that you don’t have to declare what type each variable is. In Python, variables are a storage placeholder for texts and numbers. It must have a name so that you can find it again. The variable is always assigned with the equal sign, followed by the value of the variable.
- BASIC OPERATORS IN PYTHON
Arithmetic operators are used to performing mathematical operations like addition, subtraction, multiplication and division. Assignment operators: Assignment operators are used to assigning values to the variables.
- EXPRESSIONS IN PYTHON
Expressions represent something, like a number, a string, or an instance of a class.
- PYTHON – DATA
Python Data Types: Data types are the classification or categorization of data items. Data types represent a kind of value that determines what operations can be performed on that data. Numeric, non-numeric and Boolean (true/false) data are the most used data types.
int (signed integers) − They are often called just integers or ints, which are positive or negative whole numbers with no decimal point. The real part of the number is a, and the imaginary part is b. Complex numbers are not used much in Python programming. Olympiad Exam for Class 9
The float type in Python designates a floating-point number. Float values are specified with a decimal point.
float (floating point real values) − Also called floats, they represent real numbers and are written with a decimal point dividing the integer and fractional parts. The real part of the number is a, and the imaginary part is b. Complex numbers are not used much in Python programming.
A string in Python is a sequence of characters. Strings are immutable. This means that once defined, they cannot be changed.
Like many other popular programming languages, strings in Python are arrays of bytes representing Unicode characters. However, Python does not have a character data type, a single character is simply a string with a length of 1. Square brackets can be used to access elements of the string. Olympiad Exam for Class 9
