In Plain Words

Classification is like sorting laundry into labeled baskets. Even the weird shirt must pick a basket.

It puts each input into a fixed category. You see it in photo labels and spam filters. It also checks text.

Supervised Learning
Classification is one of the most common tasks in Supervised Learning.

Cross-Entropy Loss
Cross-Entropy Loss measures the gap between the prediction and the true label.

Softmax
Softmax turns model scores into probabilities for each category.

CNN
Image classification helped make CNNs popular.
