Welcome to CS 470!

Video of the Day

Coronavirus Deep Learning Competition Cameo appearance by Geoffrey Hinton (Godfather of Deep Learning). Sign up here.

The prize is $3,500 allocated among the top 3 contestants. Sure, you get to prevent a major, world-wide health pandemic, but $1,000 or so? Not much coin. So, to increase your incentive, those of you in the CS570 track can get project credit. What a deal!

(I just checked. The deadline for submission is next Monday. I guess they really want to wipe out this bad boy soon. You can use this as a project even if you do not participate in the competition.)

Lecture : Uncertainty. 2/24/2020

Administrivia

  • I have office hours Wednesdays from 4-6 pm, Room 014 AKW. Also, I invite students to join me for lunch in a residential college after class on Wednesdays. Not this week! Microsoft AI Talks instead.

  • ULA office hours. See the [Contact Info and Schedule] as well as piazza.

  • [Assignments]. hw4 has been posted. However, it will not be graded and you do not submit it. It is meant to prepare you for questions on the midterm exam. Here are the answers to hw4.

  • Microsoft Research AI Presentations Feb 26, 12-2pm, AKW 200 (see notice below.)

    Midterm Exam: Monday, March 2nd, 10:30am

    The exam is next Monday, in class. It will comprise true/false and short answer questions. You will not be asked to write code. You may be asked to read Python code. The first 11 chapters of the textbook are in scope. The exam will not be open book. As I stated on piazza:
    An open book test would have to be much harder. I don't lean that way. I am not trying to make your life miserable. I just want you to learn about AI and maybe get excited about something.

    Also, I assume most of you read the book online, which is not going to happen in an exam.

    I will discuss sample exam questions in class on Wednesday and Friday. Until then, you can only guess, which brings us to today's topic.
