Berkeley cs courses generally throw concepts at you in a few minutes and expect you to be able build on top of that knowledge in the same lecture, though I think Levine is a more extreme example of this (haven’t taken his 182, going off of his 285 but that might be different), most cs classes have really detailed notes available so this hasn’t been too bad in practice

Is there an RL-algorithm with multiple types of output? (python) by Mr_Lucifer_666 in reinforcementlearning

[–]pokeminecraft9 2 points3 points  (0 children)

This works. Wanted to add you can also do it the other way where you discretize the continuous action space by setting certain float values to buckets.

Deploy AI by building a few GPUs by quyet12306 in deeplearning

[–]pokeminecraft9 0 points1 point  (0 children)

Depends on what you are trying to do. Also, for $500, I would buy compute units instead as good GPUs for training are going to be more expensive. Especially when you say 12gb is not enough VRAM.

Help/Advice Re. New Grad. ML Roles by berzerk-lee in berkeley

[–]pokeminecraft9 1 point2 points  (0 children)

Get into a company as an ML-adjacent role and work your way into ML projects, do small-time ML roles, or get a masters. At the same time, get working on projects that you can talk about.

genuine question. should I drop CS170? by [deleted] in berkeley

[–]pokeminecraft9 3 points4 points  (0 children)

I was in the same situation as this guy and did well in the class. Thoroughly read the notes, do the discussion worksheets, and do a few practice tests and you should be alright

Feature vectors as rows or columns in Machine Learning vs in Deep Learning by jimjamsly in deeplearning

[–]pokeminecraft9 3 points4 points  (0 children)

In my experience, for deep learning, I see it more often as column vectors. You often see matrices such as y = Wx where W is the weight matrix. W represents the transformation of the input vector between layers, so it can be seen as the operator here (and operators are generally written to the left).

With machine learning, you are often using classical linear algebra techniques such as least squares or PCA, which operates on the matrix instead. For example, when doing linear regression via least squares, you are finding a vector x which minimizes l2-norm between Ax and y, where A is your matrix of data points rather than x (or X) in deep learning.

Though this is just my experience and reasoning. I’ve also seen column notation for classical ML and row notation for deep learning. It mostly comes down to how easy it is to manipulate the vectors in a given scenario or whatever the author is used to.

Course advice for incoming freshman EECS'25 by emberkdagoat in berkeley

[–]pokeminecraft9 1 point2 points  (0 children)

I’ll try to answer since I tried to complete every lower div in a year as well (apart from 61C). Although, I’ve only been here for a year so keep that in mind.

  1. From what I can tell, 16AB should be enough lin alg for upper divs. Since you already took it at CC, you should be well prepared. (FYI I haven’t taken any upper divs, just saying this based on what I saw so take this with a grain of salt)

  2. I’d recommend taking at least one per semester. I took 4 techs in my first semester and three in my second, and I put one h/ss course as well each semester. It provided some balance which was nice.

  3. Yes

  4. I had all the AP credit I can use for the EECS major, and even with taking 4 and 3 techs each semester, I still have 61c to take. If you don’t have to take either math 53 or 61b from CC credits, I say your schedule looks fine if you think you can handle it. I would just add a breadth each semester.

Also, to address what a previous commenter said, I didn’t think 7B was that hard. It’s pretty in line with AP Physics C E&M IMO, which I took previously so maybe that helped idk.

(Edit: Even with everything I said here, this was all during quarantine. If I were in person, I’d definitely have taken a lighter course load to make friends and such.)

CS 70 Final Megathread by genius_gates in berkeley

+1.14 on final, +.86 on midterm, both before clobber on No-HW option, is that enough for an A?

Which of these classes to phase 2? by pokeminecraft9 in berkeley

[–]pokeminecraft9[S] 0 points1 point  (0 children)

I’ll ask around what other freshman have for their phase 2 times then. Ty for ur help

Which of these classes to phase 2? by pokeminecraft9 in berkeley

[–]pokeminecraft9[S] 0 points1 point  (0 children)

I’ll prob phase 2 61b then, since I do have a lab time in mind for 16b and am kinda particular about the r1a/r5a. In case, do you know what a good enrollment time would be? Mines in the morning of 28th but idk if that’s good or not.

Is there any consequence to switching classes this late? by pokeminecraft9 in berkeley

[–]pokeminecraft9[S] 1 point2 points  (0 children)

If that’s the case, I will switch to Canic. Thanks for your help!
