41. What Is a Neural Network (Simple Explanation)
41.4 Where Nets Show Up in Apps
Why. Connect nets to apps students already use — without claiming real company internals.
What. Fictional product stories: photo search for groceries, voice-to-text in Hindi/English mix, recommend next pedha flavour from past carts. Deep learning shines when inputs are rich (images, audio, long text).
How.
Match problem → network family (preview)
- Tables with dozens of columns → often classical ML first (Chapter 46).
- Images → CNNs (Chapter 47–48).
- Text / sequences → transformers (Chapter 49–50) and Gen AI course for ChatGPT-style tools.
print("Tables -> try sklearn first")
print("Images -> CNN")
print("Long text -> transformers / LLMs (Gen AI lane for chat apps)")
