Draw a tree and on each leaf, write how AI can help different parts of nature. For example, AI
helping forests by monitoring health or AI helping animals by tracking migration patterns.

HOW MACHINES LEARN

Machines learn through a process called machine learning (ML), where they use
examples (data) to identify patterns or make decisions. Rather than being explicitly
programmed for every task, they improve their performance over time by training

on examples. Here's a breakdown of how it works:

 Data Collection: First, a machine is given data. This could be anything from images
to text or numbers. For example, if you wanted a machine to recognise pictures of
dogs, you'd collect a large set of labelled images (some with dogs, some without).

 Training: The machine learns from these examples. This involves running the

data through algorithms, which try to map input (like an image) to an output
(such as "dog" or "not dog"). The system adjusts its internal settings based on
how accurate or inaccurate its predictions are.

 Testing and Adjusting: Once the machine has been trained, it's tested with new

data that it hasn't seen before. This step helps the machine check whether it's
learned the right patterns. If it makes mistakes, the model adjusts its parameters
to improve.
