## Curious how machine learning image classifier work?

Machine learning image classifier utilize Neural networks, the backbone of artificial intelligence, can seem complex. But let's break it down with a simple example. Imagine trying to teach a computer to differentiate between a cross (x) and a circle (o).

We start by representing each image as a grid of pixels, with 1 for a colored pixel and 0 for a white one. Our neural network consists of a single neuron that calculates a weighted sum of these pixel values. If the result is positive, it's classified as a circle; if negative, a cross.

Initially, all weights are equal, leading to incorrect classifications. To improve, we adjust weights based on image characteristics. For example, a higher weight for the center pixel can help distinguish crosses from circles.

While we can achieve perfect classification for these simple shapes, more complex images, like smiley faces, pose challenges. Our simple neuron might struggle to accurately classify all variations.

This example highlights the core concept of neural networks: learning through weight adjustments. However, it also demonstrates the limitations of simple models when faced with complex patterns.

**Key Takeaways machine learning image classifier:**

Neural networks learn by adjusting weights to make accurate predictions.

**Explanation**

The code above implements a simple neural network with a single neuron to classify images of crosses and circles. It demonstrates how the network can learn by adjusting weights based on the training data. However, the code also highlights the limitations of this simple model, as it might not be able to accurately classify more complex images like smiley faces.
