What's inside an AI if you open it up? — Neural networks

1 · Think first

Before the lesson, write down what you think the answer is.

2 · Experiment · Put it in order

Try it — What happens inside a neural network, in order

What did you change in the experiment, and what happened?

3 · Quiz

Circle the right answer.

  1. Q1What's closest to what one dot in a neural network does?

    1. ① Multiplies by weights, adds, checks a threshold
    2. ② Memorizes whole sentences
    3. ③ Fetches answers from the internet
    4. ④ Writes down its own rules in words

  2. Q2Why can a neural network make complex judgments?

    1. ① Each dot is really smart
    2. ② Simple math builds up over many layers
    3. ③ People wrote the answers in advance
    4. ④ Its screen is big

  3. Q3What does a 'weight' decide?

    1. ① The size of the text
    2. ② Screen brightness
    3. ③ How strong a signal passes
    4. ④ Internet speed

The takeaway in my own words

“One dot can only multiply and add. Stack them in layers, and out comes judgment.”

Rewrite this line in your own words.

DAY 46 · What's inside an AI if you open it up? — Neural networks

  1. Q1 · Answer ① Multiplies by weights, adds, checks a threshold One dot only multiplies, adds, checks the threshold and passes it on. The amazing part doesn't come from one dot — it comes from huge numbers of those dots stacked in layers.
  2. Q2 · Answer ② Simple math builds up over many layers The first layer only picks up small bits like lines. Those bits become eyes and ears in the next layer, and a cat in the last one. Depth is what makes the judgment.
  3. Q3 · Answer ③ How strong a signal passes Each link has a different weight, so some signals pass on strongly and others weakly. Training is really just fixing these weight numbers, bit by bit.

Today in one line · One dot can only multiply and add. Stack them in layers, and out comes judgment.
