What Is AI?
Two words: Artificial. Intelligence. Break them apart and the whole idea clicks.
Amazing Things AI Can Do
Talks, sees, draws, drives, helps doctors. The wild stuff AI is already doing today.
AI or Just a Program?
Some gadgets look smart but aren't. The test: does it learn from experience?
80 Years of AI
From Turing's wild question to ChatGPT — the whole story in one scrubbable timeline.
Three Ways AI Learns
Supervised, unsupervised, reinforcement — three recipes for the same big idea.
Humans Pick, or Machines Learn
Every program is a box with knobs. Until now, WE set them. What if the computer could?
When Does AI Even Make Sense?
The 5-minute rule: if you can write the rule in 5 minutes, don't use AI.
Data Is the Teacher
Every AI has one teacher: data. If the teacher is biased, the AI is too. Garbage in, garbage out.
What Does "Learn" Mean?
Guess. Check. Adjust. Repeat. That's it — that's learning.
Fit the Line
Watch a computer adjust its knobs until its "wrongness" number shrinks.
When AI Memorises Too Much
Learning answers vs learning the pattern. Hide some examples (train/test split) and see if the AI truly gets it.
A Single Neuron
The box with knobs, revealed: inputs, weights, a squish — that's a neuron.
A Network of Neurons
Stack neurons. Feed outputs into inputs. Now you have a brain of sorts.
Where Knowledge Lives
The weights ARE the AI. Training fills them in (weeks). Inference runs new input through them (milliseconds).
Types of Neural Networks
CNN sees. RNN reads in order. Transformer understands context. Three shapes, three superpowers.
The AI Lifecycle
AI is never "done". Collect → Train → Use → See new data → Improve → Repeat.
Is the AI Sure?
AI always guesses. It shows confidence, not truth. And sometimes confidently wrong — hallucinations and all.
AI Ethics & Bias
Bias starts in the data. Fairness is everyone's job — including yours.
Privacy & Safety with AI
Your data is yours. AI hallucinates. Voices and photos can be faked. 5 rules to stay safe.
