What do we mean by intelligence? 
Intelligence is the ability to learn and to use what you have learnt 
in new situations. Intelligence keeps growing – the more we deal 
with new situations, the more our intelligence grows. 
With advances in technology, machines are also becoming 
intelligent, just like humans. This is known as Artificial Intelligence 
(AI) and it is progressing very rapidly – what we did not imagine 
even a few years back is possible now (Figure 4.1). 
Before learning about AI, let us discuss how we learn. Imagine 
that, on the first day of school, you meet many new people. Your 
brain will try to remember their faces and names, but you may 
not be able to remember all of them. After few meetings and 
interactions, your brain will start recognising each person and 
recalling their names as soon as you see them. After few days of 
interaction, you will be able to recall many qualities of that person.
AI works in a similar way. For example, if we want a machine 
to recognise an image, we need to show different images of the 
same object. We do this by uploading these images with proper 
instructions. Suppose, we want a machine to recognise a banyan 
tree. We will upload many different images — banyan tree in the 
shade, in light, different stages of growth (including many pictures 
of saplings), from different angles, in different geographies, full 
photos, partial photos — this will have to be done carefully to 
ensure the machine has maximum possible data related to how a 
banyan tree looks.
We also need to teach the machine to associate images with 
their name — in this case, ‘banyan tree’. Slowly, as you upload 
more data and associate it with the name, the machine will start 
recognising images, even those it has never seen before and 
connect them to the correct name. You can even teach the machine 
to connect to other information related to the banyan tree. In 
this way, you can keep adding the connections the machine can 
make — e.g., scientific name, conditions for growth, uses, animals 
who live in it, and whatever else may be useful for humans. This 
process is called ‘Machine Learning’, and AI makes it possible.

Similarly, you can teach the machine to recognise audio 
recordings of music and sounds — e.g., with a different tone, 
using different musical instruments — and video recordings — 
e.g., different backgrounds, different angles.
AI is being used in various ways to help humans. AI can be used to 
automate repetitive tasks, thus, reducing human efforts and increasing 
productivity.
As its use increases, and scientists and engineers explore how it can be 
expanded, it is fast becoming a part of our everyday lives. 
Right now, we use AI without even thinking of it. Various apps for 
navigation while driving, image recognition, translation, and so on are 
part of our lives. You may have heard of robots that help doctors operate 
from a city far away from the patient, or robots who can teach students. 
Till few years back, some of these functions of AI were part of science 
fiction books and films. And now they are fast becoming a reality.
Even though AI may keep learning by itself, as it gathers more 
information there are certain things it cannot do. For example, can 
we teach AI to feel emotions? AI may be able to identify various 
aspects of nature that make it beautiful, but it will be able to convey 
that an artwork makes you feel good only when you train it to do 
so – it will never be able to feel emotions as humans do.  
What will I be able to do?
At the end of the project, you will be able to:
1. Understand how AI can be a useful tool for humans.
2. Collect data that can be used to create an AI Assistant.
3. Train a machine to recognise data based on your instructions.
4. Create an AI Assistant to help someone learn about your 
locality.

What will I need?
Devices: You will need a computer with a webcam and a 
microphone/speaker or a tablet with Internet access. You will also 
need a camera that can take photographs and record audio data. 
In case you do not have such a device, you can use the smartphone 
of a parent/teacher.
AI Tools: Teachable Machine, Scratch, and any other tool you 
may find useful to build the AI Assistant.
You can search for more AI tools by using these keywords:

How do I keep myself and others safe?
Internet safety: Discuss the safety precautions which should 
be taken while accessing the Internet with the teacher and your 
peers. Make a list of ‘dos’ and ‘don’ts’. Make sure you follow this 
list while working. If in doubt, ask your teacher. Remember to 
limit your screen time as advised by your teacher and family 
members (Figure 4.2).
Sensitivity: Get permission before collecting data or taking 
photos. For example, if you are taking a photograph of a shop, ask 
the shopkeeper for permission. Be respectful to all and try and 
understand the reasons people do 
things that may seem strange to 
you, e.g., a custom that is 
unfamiliar to you. Take care when 
taking photographs of plants and 
animals – ensure they and you are 
both protected from harm.

What do I need to know before I start?
Before you start, you should know basic functions on the 
computer, and how to use the Internet. You should be able to take 
photographs and upload them.
But, before you begin, the first thing you must do is to 
understand what AI can and cannot do. Once you understand this, 
you will be able to make decisions about what the AI Assistant 
should do.
Activity 1: Human vs Machine: Who is Better at What?
Start by exploring three tasks related to what makes humans and 
machines special, and discovering how both work.
1. The speed with which a machine and you can calculate: 
Speed Test. You can do this using pen and paper, and a 
calculator. You can use a watch or borrow your teacher’s 
smartphone to keep track of time.
2. Check how accurately a machine can guess what you 
have drawn: The Creative Guessing Game. Use ‘Quick Draw’ 
or a similar drawing game. Draw and let the computer 
guess what it is.
3. Compare who can better guess the time taken to reach 
school: The Prediction Test. Think of how long it usually 
takes to reach school. Pick any date and predict how long 
you will take to reach school. Now, ask Google Maps how 
long it will take. Compare the predictions.
