Discover the magic behind AI and machine learning through interactive visualizations and fun examples!
Neural networks are computer systems inspired by the human brain! Just like our brain has neurons that connect and pass information, artificial neural networks have digital "neurons" that work together to solve problems.
Think of them as a team of tiny workers, each specialized in a small task. When they work together, they can do amazing things like recognizing your face in photos, understanding what you say to voice assistants, or even creating art!
Neural networks learn through a process called training. Let's explore this step by step!
The input layer is like the front door of a neural network. It's where the network receives information to process.
For example, if a neural network is identifying animals in pictures, the input layer would receive the pixel values of the image. Each neuron in the input layer might represent one pixel's color value!
The output layer gives us the final result. Each neuron in the output layer represents a possible answer.
In our animal identification example, there might be neurons for "cat", "dog", "bird", etc. The network activates the neuron that best matches what it sees in the image!

Training a neural network is like teaching a student with practice problems and feedback:
The network makes a prediction based on its current knowledge.
We compare the prediction with the correct answer to see how wrong it was.
The network adjusts its internal connections to reduce the error next time.
We repeat this process with many examples until the network gets good at the task!
Watch how data flows through a neural network, from input to output!
Adjust the parameters below to see how they affect the neural network's performance in recognizing handwritten digits!
Just like there are different types of tools for different jobs, there are different types of neural networks for different tasks!
The simplest type where information flows in one direction, like a one-way street!
Specialized for images, like having special glasses to see pictures better!
Great for sequences like text or speech, like remembering what happened before!
Two networks competing to create new things, like an artist and a critic working together!
The human brain has about 86 billion neurons! While artificial neural networks are much simpler, they're inspired by how our brain works.
Some neural networks called GANs can create stunning images, music, and even poetry that look like they were made by humans!
Just like children learn by seeing many examples, neural networks learn by processing lots of data. The more examples they see, the better they get!
