MachineLearning-Lecture10

Instructor (Andrew Ng) :So just a couple of quick announcements. One is, first, thanks again, for all of your Problem Set 1 submissions. They’ve all been graded, and we’ll return them at the end of lecture today. If you’re an SEPD student, and you submitted your Problem Set 1 by faxing it to us, then we’ll return it to you via the SEPD career. And if you handed in a hard copy of your homework, instead of in person or in the late hand in box, then they’ll be available in this classroom at the end of lecture today for you to pick up. And homework’s that aren’t picked up today, we’ll leave at the late hand in box here in the basement of the Gates building; which, by the way, you can actually access after hours, in case any of you didn’t already know that.

So you can pick them up at the end of class today or again, if you’re an SEPD student, and we got your homework by fax, we’ll return it to you via the SEPD career. And if you haven’t seen it already, Problem Set 2 has also been posted on the web page. I think it was posted online last week. So do make sure you download that if you haven’t already. I’d like to say, many of you actually did very well on Problem Set 1. As an instructor, it’s actually sort of personally gratifying to me when I see your homework solutions, and I say, like, “Hey, these guys actually understood what I said,” so that was actually cool. And I shall also say, thanks to all the people in this class for working as graders, and stayed up very late on Monday night to get all the grading done, so just a big thank you to the graders as well.

Let’s see, one more announcement. Just a reminder, that the midterm for this class is scheduled for the 8th of November at 6:00 p.m. So the midterm will be – that’s about two weeks from now, I guess. So the midterm will be open book, open notes, but please don’t bring – but no laptops and computers. SEPD students, if you live in the Bay area, then I’ll ask that you come in person to Stanford to take the midterm in person on the evening of the 8th of November. If you’re an SEPD student, and you live outside the Bay area – so if you can’t drive to Stanford to take your – then please email us at the usual class mailing address: cs229qa@cs.stanford.edu. This is the same address you see on our web pages.

If you can’t physically come in to attend the midterm because you live outside the bay area, then please make sure you email us by next Wednesday, so they will make alternate arrangements for the midterm. And for regular Stanford students, as well; students that aren’t taking this via SEPD, and if you have a conflict. So if you have some other event of sort of equal or greater importance than the 229 midterm, like another midterm of another class that conflicts, please also email us by next Wednesday at the usual staff mailing address to let us know; okay? And so if I don’t hear from you by Wednesday, I’ll assume that you’ll be showing up in person for the midterm. Okay. Any questions about any of that?

explain assimilatory nitrate reduction
Esinniobiwa Reply
Assimilatory nitrate reduction is a process that occurs in some microorganisms, such as bacteria and archaea, in which nitrate (NO3-) is reduced to nitrite (NO2-), and then further reduced to ammonia (NH3).
Elkana
This process is called assimilatory nitrate reduction because the nitrogen that is produced is incorporated in the cells of microorganisms where it can be used in the synthesis of amino acids and other nitrogen products
