MachineLearning-Lecture19

Instructor (Andrew Ng) :All right, good morning. So just one administrative thing before we go into today’s technical material. So let’s see. The final projects poster session presentations will be on Wednesday the 12th of December. I guess that’s one week from this Wednesday. So similar to the mid-term exam, if you physically live in the Bay Area then please come in person to do the poster session. So this means you guys, you know, so if on campus students, and SCPD students are that, so they live in the Bay Area. If, for some reason, you live in the Bay Area, but aren’t able to come in in person to the poster session, please send us an e-mail as soon as possible at the usual class mailing address cs229qa@cscenter.edu; it’s the one on the course website; let us know. And if you’re an SCPD or SITS student and if you live physically outside the Bay Area then you’re exempt from the poster session, I guess. The poster session itself will be held at 8:30 a.m. on this – so the registrar assigns classes a certain time slot for final exams, so this class doesn’t have a written final. We use that time slot instead for the final poster presentations. So they’re about, I don’t know, I think there are, like, about 70 posters in this class. So in order for me to be able to see everything in a reasonable amount of time please prepare, like, about a two-minute presentation, so that as I go around the posters next Wednesday you can just briefly tell me about your work. And that’s the short, and then as I promise every year, I personally read every single word of every single final project write-up, so don’t worry about telling me everything, every little detail, of what you did because when you send me your final project write-up – so I promise I read every single word of every write-up, so I get all the details from there. But to go in the process presentation is actually first and foremost for you guys also to have a look at what other cool things people in the class are doing and based on the models, I’ve been flipping through the models, of all the very cool projects this year. So at the poster presentation too hopefully you can see what your colleagues, your classmates, have been doing and have fun doing that and also for me to just get a very brief sense of the things you’ve been doing. Okay?

The posters themselves, we will supply poster boards if you want them. You’re welcome to buy your own poster boards, but in a few days I’ll send instructions on where you can pick up a poster board. If you do get a poster board from us we do reuse them. We do recycle them from year to year, so if you do get one from us that I ask you to return it at the end of the poster session next Wednesday. So poster boards are, I don’t know, maybe about this wide and about this tall, so you can print out several pieces of paper. Print out several slides and attach them to the poster board. And we’ll provide easels, as well, for the poster presentation. Okay? So next Wednesday, come a little bit before 8:30 a.m. and we’ll meet on the first floor of the Gates lobby. So around the first floor of the Gates lobby around Gates 104 and we’ll set up poster there. Okay? Are there questions about the poster session? No? Okay, cool. Let’s see.

Chemistry is a branch of science that deals with the study of matter,it composition,it structure and the changes it undergoes

chemistry could also be understood like the sexual attraction/repulsion of the male and female elements. the reaction varies depending on the energy differences of each given gender. + masculine -female.

can someone explain to me, an ignorant high school student, why the trend of the graph doesn't follow the fact that the higher frequency a sound wave is, the more power it is, hence, making me think the phons output would follow this general trend?
Joseph Reply
Nevermind i just realied that the graph is the phons output for a person with normal hearing and not just the phons output of the sound waves power, I should read the entire thing next time
Joseph
Follow up question, does anyone know where I can find a graph that accuretly depicts the actual relative "power" output of sound over its frequency instead of just humans hearing
