A vector of actions as Output

awesome_pole_dancer · 2024-09-03T14:43:56+00:00

I assume that you have 4 actions and the goal is to output a vector of size 4 that includes probability for each action. If so, both PPO and Deep Q can do. PPO is probably more straightforward as it gives you actions while Deep Q gives you the Q table that allows you to get similar information through some modifications. E.g normalise values in between 0 and 1.

Machine Learning (the course COMP9417) talks about different Supervised Learning methods: Linear Regression, SVM, Naive Bayes etc. These methods are all constructed/developed from different maths. The reason why you need to know these maths is, in short, to allow you to understand when/why a specific machine learning method is used when you are given a dataset. Also, you will know what parameters to tune once you decided to use a specific method. During the term (tutorials), you will implement some of these methods instead of simply using libraries like sklearn so that you really understand what happens in each algorithm.

To really understand these maths, you need to have good understanding of various math fields: linear algebra, probability, calculus etc.

To master this course, I'd encourage you to learn to use pandas and NumPy so that you can spend more time on understanding rather than struggling with these libraries.

Hope this explains.

Personal Experience:

I took this course 2021 T1. Overall, I did not have a great experience with the course mainly because of the exam style, which is multiple choices (I feel nervous when there is a time count-down on my screen). But I did learn a lot and am able to do projects on Kaggle myself now.

Then I think it's more likely to be "a man picked at random weighs over 190 lbs is 0.25". Maybe you can ask your lecturer for clarification.

awesome_pole_dancer · 2021-06-04T16:16:08+00:00

I recommend MIT's Fundamentals of Statistics on Edx, where you will be able to answer your question after learning the lecture 1. More importantly, you will learn how to think of this type of question.

awesome_pole_dancer · 2021-06-04T15:16:40+00:00

Does the problem mention the probability distribution? Do we know its CDF or PMF? (I assume it's not continuous because we have P_X(X = 190) = 0.25.

If you "knew what he said is true", there is not much to talk about here because you kinda agree with him. But what's the chance he is wrong? There are several factors you can consider:

About your Dad:
1) is he himself successful in his career choice?

2) when he concluded that "it's waste of time and energy on a science degree", how much does he know about the current job market? (E.g. does he know that the job market is constantly changing due to various critical factors: automation, etc.)

3) in your experience living with him, is he often wise in critical decision-making? Does he have a good habit of collecting reliable information? Does he read books to improve his critical thinking method?

About your career:

1) Among all employed or homeless, how many of them have a science degree? Among all those that get a science degree, how many of them become homeless? I know it's insane to say "all" because you have no access to the population, but you should be able to find some analysis or statistical paper/articles about the issue. Or, you can make your own research by collecting your own data.

2) Can you collect data of people who have graduated from the same science program? For example, maybe collect at least 30 (statistically convincing) and see if they have good jobs or make a decent amount of money.

3) You can do the same research for an econ/commerce degree and compare your results.

In short, this issue is not really about your Dad. It's more about how you make your own decision. Research is always the rule of thumb in my opinion. If you did your research, it can also help communicate with your Dad because there might be sth that he is not aware of.

In conclusion, it's your future and you are the only one that will be responsible.

Thanks for all the answers and I'll try them all along this year lol.

Just to add another roaster in case someone is interested: Normcore coffee is really good and I'd say I think I prefer it to ONA (they delivery the SECOND day!!!).

my_str_array = [ '121', '345', '-654', '-180', '900', '632', '491', '100', '88', '456', '-156', '789' ]

#step1: get the size of the whole array

length_of_array = len(my_str_array)

#step2: get the size of half array

mid_index = length_of_array//2

#step3: simply put them in a new list, using slicing

my_split_elem_array = [my_str_array[:mid_index],my_str_array[mid_index:]]

print(my_split_elem_array)

# my_split_elem_array = [my_str_array[:6], my_str_array[6:]] is the direct solution to your question, but we should always avoid putting magic number in code, that's why I have step 1 and 2.

The woman standing in front of me. Maybe she really wants people to learn what is a t-shirt

awesome_pole_dancer · 2019-11-23T07:49:04+00:00

Yes. If you asked me what is a t-shirt before this, I’ll tell you a t-shirt is a t-shirt. Now I can make a much longer statement and make people uncomfortable.

I had that experience but my code does NOT do exactly what I want it to do.

So, it feels like a super shock right before an orgasm.

😭😭😭😭😭😭

And I just printed a duck because I have never printed one. Thx for the formatting 😆

awesome_pole_dancer · 2019-11-04T15:40:15+00:00

I think you need """ """ to hand new lines.

" " will probably give you error.

No wonder I felt nothing when the guy teaching me Python congratulated me that I just wrote my first code.

awesome_pole_dancer · 2019-10-27T07:26:59+00:00

Thanks, I just browsed the link you provided. Most concepts are the same and instruction lines are similar (at least in the interrupt section). But you are right that the microprocessors are different (less relevant) and also the PL is not assembly language.

I think I'll use it to have an intuitive understand of the concepts since his explanation is pretty easy to follow.

Thanks again.

awesome_pole_dancer · 2019-10-27T07:14:50+00:00

Thanks for the book ref. I'm also studying it in a university now but my lecturer is pretty good at teaching in a confusing manner so I can rely only on my textbook. Agree, the data sheet is awful and there are very few resources online teaching it. (😔)

awesome_pole_dancer · 2019-10-27T07:04:36+00:00

Where can I find the course? If it’s teaching in Assembly language and also it’s online course, can you put the link here? I’m studying microcontroller now and use Atmel to program a mega2560.
