    "\n",
    "I'll be using a *top-down* teaching method, which is different from how most math courses operate.  Typically, in a *bottom-up* approach, you first learn all the separate components you will be using, and then you gradually build them up into more complex structures.  The problems with this are that students often lose motivation, don't have a sense of the \"big picture\", and don't know what they'll need.\n",
    "\n",
    "If you took the fast.ai deep learning course, that is what we used.  You can hear more about my teaching philosophy [in this blog post](http://www.fast.ai/2016/10/08/teaching-philosophy/) or [in this talk](https://vimeo.com/214233053).\n",
    "\n",
    "Harvard Professor David Perkins has a book, [Making Learning Whole](https://www.amazon.com/Making-Learning-Whole-Principles-Transform/dp/0470633719) in which he uses baseball as an analogy.  We don't require kids to memorize all the rules of baseball and understand all the technical details before we let them play the game.  Rather, they start playing with a just general sense of it, and then gradually learn more rules/details as time goes on.\n",
    "\n",
    "All that to say, don't worry if you don't understand everything at first!  You're not supposed to.  We will start using some \"black boxes\" or matrix decompositions that haven't yet been explained, and then we'll dig into the lower level details later.\n",
