Supervised Learning: Crash Course AI #2

  • Today we’re going to teach John Green Bot how to tell the difference between donuts and bagels using supervised learning! Supervised learning is the process of learning WITH training labels, and is the most widely used kind of learning with it comes to AI - helping with stuff like tagging photos on Facebook and filtering spam from your email. We’re going to start small today and show how just a single neuron (or perceptron) is constructed, and explain the differences between precision and recall. Next week, we'll build our first neural network.
    Read more about the perceptron and update rule here: jontysinai.github.io/jekyll/u...

      If we made bagels average small as donuts J green bot will gets more lower precision , diameter and mass has no real causal relations to donuts and bagels. Learning depends on the real causal relations and procedure had been designed to experience. Also procedure design depends on real causal relations.

      I disagree with the concept of toasting because I feel that it detracts from the texture and flavor of Noo Yawk bagels (and makes the cream cheese runny and messy). However, you've given me the idea of toasting donuts (particularly the "cake" type), in order to possibly achieve the consistency of home-baked corner pieces of cornbread!

Then is not that easy compare humans and AI or create AI copying human behaviour.

    I know this is simplistic for the purpose of explaination but they really missed an opportunity to add a simple classification based on the ratio of mass to size. If it’s large it’s a bagel unless it’s light. Truly the fact that we’re picking light for donuts and heavy for bagels is good but Considering that all the data is there it makes more sense to do it as a ratio.

    At 2:53 this description to neuron’s working mechanism is simple as too simple as easy to mistake students to understand. Reality the working mechanism of neuron has been designed more much complex than you think (because of natural selection).
    3:10 neuron talking to each other by passing neurotransmitter (and the electrical signal is not the only way the neuron talking to another neuron)
    And the neuron isn’t using electric action potential directly to another neuron (this animation will makes you think wrong easy) the electric signal will makes the neurotransmitter transmit to another neuron and it will not save the energy if the previous one sends the neurotransmitter it doesn’t recognize.

      but cassette technology has come a long way. standard sized data cassettes used for backup and storage can hold MANY gigabytes of data, and some newer ones can hold more than a hundred terrabytes. ...the problem comes from random read cycles... it takes hours to load all of the data from the cassette.
