The Big Bang of Deep Learning

Every field has a split point. For deep learning, that year is 2012.

Before 2012, computer vision struggled. Researchers used a database called ImageNet to test systems. The goal was to sort images into 1,000 different categories.

For years, error rates stayed around 25%. Progress stopped. No one knew how to move forward.

Then, a team led by Alex Krizhevsky changed the game. They used a Convolutional Neural Network (CNN).

Instead of humans writing rules for what an image looks like, the network learned directly from the pixels.

The results were massive. They cut the error rate nearly in half in one year.

This shift changed everything. It moved AI from research labs into the real world.

The impact spread fast:

  • Netflix used it for better recommendations.
  • Siemens and GE used it for medical imaging.
  • Car makers used it for autonomous driving.
  • Tech giants like Google and Apple built it into every product.

This success relied on hardware. Training these networks requires massive math. GPUs, originally made for video games, proved perfect for this math. This drove the rise of NVIDIA.

But remember, market trends are complex. NVIDIA's growth also tied to the crypto mining boom. Never assume one single cause for a market shift.

Deep learning also conquered games.

Chess was solved by brute force. Go is different. The possible moves in Go are too many for any computer to count. In 2016, AlphaGo proved that deep learning could learn strategy without human help. It learned by playing against itself.

The lesson is simple.

Old methods failed because humans had to hand-code the rules. We hit a ceiling. Deep learning broke that ceiling because systems now learn their own patterns from raw data.

In this series, I will break down my deep learning course notes. We will look at how these networks actually work.

Next, I will explain what happens inside a network when it learns.
