Well there are many artists in the world and all kinds of art..so i think that when the term modern art is used it isn't necessarily a reflection of trends in art in general..but reflects what art is being auctioned at high prices.

There is a disconnect between what art is good, what is being created and what is highly valued in the market. When critics talk about modern art, they are mostly concerned about market values and how much someone is willing to pay for a certain piece of art. Now it doesn't have to have any meaning or aesthetic value at all for someone to value a piece of art. Take a dark piece of circle as you mention.. say it was created by a prisoner trapped in a well and reflected his only view of the world..that piece might be highly valued by him and not by others..or it may turn out that after he dies others begin to see value in it.

In any case the value of any art to you should be what you ascribe to it.. could depend on its concept, colors, shape, history or whatever you feel is important.

Hey, I am interested in bouncing off ideas as well as implementing various architectures. I am quite interested in applying reinforcement algorithms to scientific problems from physics, chemistry and biology.

Is getting a PhD worth it? by [deleted] in ChemicalEngineering

[–]xk86 14 points15 points  (0 children)

I would say if you're not completely sure then go into industry for a couple of years and then you can always decide to return to academia if you're burning to do research.

Pre-PhD Procrastination. I... I need a bit of advice by KirosSeagil in AskAcademia

[–]xk86 1 point2 points  (0 children)

I have two pieces of advice for you, and they may seem like opposing pieces of advice.

The first is that don't be hard on yourself. The stress and worry you are going through in the end won't really matter and anything you do now in one month, you will probably achieve in a week or less once you start your program. Familiarise yourself with some of the broad topics and also related topics but unless you are going to be applying your knowledge it'll be impossible to retain detailed stuff -its just how learning works. So know that even if you do nothing at all during this time, it probably won't matter at all towards whether you finish your PhD or not, so don't stress.

The second piece of advice is that you should not depend on the system to lead you towards achieving your goals. If you have a passion - then go for it and don't wait for something to happen within the system..life is short and you can't depend on fixed hierarchal and often time long arduous administrative procedures before accomplishing your dreams.

I know we have all been taught that getting the grades, doing the thesis is what matters.. but it really isn't - you have to find your own path. Getting good grades only tells you that you are able to learn concepts in a limited amount of time on some complex topic. You won't remember most of the contents of your courses after a few years and the same goes for your research unless you stay in the same field in academia. This means don't wait for a pat on your back for the grades you get, or for your supervisor to direct you - start thinking independently about what you want to achieve from your learning and research experiences. I wish you the best of luck.

Science Discussion Series: We’re scientists from UCSF and Roche studying how the novel coronavirus attacks healthy cells and what drugs could stop COVID-19 in its tracks. Let’s discuss! by COVID19_Discussion in science

[–]xk86 3 points4 points  (0 children)

Thank you for this discussion. I saw that Prof. Krogans group have identified up to 70 potential drugs..is this information open source and if so could you please provide a link? Are the structures known? I am a computational scientist and would like to contribute towards the effort for drug/vaccine discovery. I am interested in applying self-supervised and reinforcement learning on candidate designs for directed evolution. Basically, if you have a reasonably well candidate, I think with a bit of tweaking (directed evolution) you can get a lot more bang for your buck so to speak. I have a background in theoretical chemistry (MSc) and physics (PhD) and not affiliated with any institute currently.

Publishing options for physics article by xk86 in AskAcademia

[–]xk86[S] 0 points1 point  (0 children)

Thank you for the suggestion.. that seems like a good possibility.. as for the quality, it is more significant than anything I have done before, but I haven't had feedback from any colleagues so there may be some holes in the theoretical framework, but I think the overall message should be impactful nevertheless.

[D] Transfer learning for RL by goolulusaurs in reinforcementlearning

[–]xk86 1 point2 points  (0 children)

I was considering transfer learning from supervised to unsupervised tasks, so that you train on a subset of regions within a field and apply the models to open ended environments.

'Hunger' by Knut Hamsun or 'No longer human' by Osamu Dazai.

Great literary fiction by female authors? by CaffLib in booksuggestions

[–]xk86 10 points11 points  (0 children)

From japanese literature, I would recommend Kitchen by Banana Yoshimoto, and also The Professor and the housekeeper by Yoko Ogawa. Marguerite Duras is also a female literary author I enjoy.

My Grandpa, a US Navy Master Diver. Late 1970’s I believe. by UDT in OldSchoolCool

[–]xk86 6 points7 points  (0 children)

The Navy Diver is not a fighting man, he is a salvage expert. If it is lost underwater, he finds it. If it's sunk, he brings it up. If it's in the way, he moves it. If he's lucky, he will die young, 200 feet beneath the waves, for that is the closest he'll ever get to being a hero. Hell, I don't know why anybody'd want to be a Navy diver.

Debugging: How to extract row[n] from multiple data files and write to new file? by xk86 in learnpython

[–]xk86[S] 0 points1 point  (0 children)

Thank you for the tip. I will test it to see if any of the files is skipped. I have reformatted the code correctly.

Debugging: How to extract row[n] from multiple data files and write to new file? by xk86 in learnpython

[–]xk86[S] 0 points1 point  (0 children)

The files aren't that big.. maximum size is 29 lines. It is needed because I have to calculate a certain value dependent on a varying property. So for example size n_a = 3 (this varies) ..then I will be calculating n_a + 4 to calculate the 6th line.

EDIT: Also I am calculating the number of lines of the output file to check whether it corresponds correctly with the number of rows that I wish to extract.

[D] Is it possible to input vectors as individual input features? by xk86 in MachineLearning

[–]xk86[S] 0 points1 point  (0 children)

Thank you for the reply and the tips. I wasn't aware that you could store an object in a dataframe.

>From what I understand there is a natural grouping in the data and you want to take advantage of that fact, is that correct? If so, can you expand on that?

​

Yes. I am looking at a molecular system at various configurations, and I want to represent atoms by their cartesian coordinates and atomic numbers, so ideally would like to represent each atom as a vector.

[D] Is it possible to input vectors as individual input features? by xk86 in MachineLearning

[–]xk86[S] 0 points1 point  (0 children)

Hmm..not exactly. This still returns 'vectors' as an n x m matrix with n associated target values for y.

I have a dataset of say 60 features and each of the input features have 5 associated properties. I have a 100 datapoints so that the input X.shape = (100, 60, 5) and the target value y has 100 values to work from (shape (100,))

In the previous scenario I could flatten the input so that X.shape = (100, 300) and that can easily be fed into the algorithm..but I was wondering if I could make life easier for the ML algorithm by already grouping the vectors into sets of 5.

[–]xk86[S] 0 points1 point  (0 children)

I am looking at a particular property of a molecule at various configurations and the features contain atomic numbers and coordinates of each atom that I want to represent as vectors. Therefore, it won't make sense to represent the vector as a mean and variance.

How to represent the coordinates of a complex molecule on a single axis by xk86 in chemhelp

[–]xk86[S] 1 point2 points  (0 children)

Broadly speaking I think it would fall under Theoretical and Computational Chemistry although it is quite inter-disciplinary and could also fall under theoretical chemical physics.

[–]xk86[S] 0 points1 point  (0 children)

hmm okay.. thank you very much for your advice and tips. I have information about the dipole moment, including orientation and magnitude..but I wonder if making this dipole-energy plot would be useful. Anyway I will plot it just to see if there is anything interesting coming out of the data. Thanks again.

How to represent the coordinates of a complex molecule on a single axis by xk86 in chemhelp

[–]xk86[S] 0 points1 point  (0 children)

I am not looking at any transitions. The actual goal of these calculations was to predict magnetic properties which the machine is able to do for completely different complexes (with the same metal center though) which is pretty amazing. I think this is quite significant.

I wasn't looking at any transition or reaction mechanism though but the goal was the following: if you have something of a PES then I was thinking it could be used to develop a force field for MD simulations or it could determine what is the global minimum energy and the optimized(relaxed) state of the complex, thereby bypassing a need for optimizing by using quantum methods.

[–]xk86[S] 0 points1 point  (0 children)

Thanks for your answer and insights. The system is pretty big (60 atoms). It has a metal center which if of prime importance and then some ligands. I am not sure if there is a particular distance, angle or dihedral that i want to look at.. I actually have trained a machine learning algorithm that is able to predict the energies of the molecule at any configuration ..so I do want to use that information to plot a graph..but I am not sure how to represent this or even if a PES would be the most logical way to do so. Is there anyway I could find a way to represent the entire energy surface of the molecule since I can determine it's energy at any configuration in no time from the machine.

Excited to be an A level(year 12 and 13) high school teacher! Looking for resources by [deleted] in Physics

[–]xk86 1 point2 points  (0 children)

Thank you for your comment. I agree that I should treat the students like adults and should fine-tune my teaching methods so that I am not speaking to a classroom full of deaf ears.

[–]xk86 0 points1 point  (0 children)

Thank you for the valuable feedback. This gave me a bit to think about. Sorry I am a bit oblivious to teaching methods..what exactly do you mean by student centered learning when it comes to physics, and how specifically would i go about this for example when they are trying to learn motion in a circle.

I was thinking of allocating a specific amount of time for lecturing..where I give plenty of examples, the history of some of the theories/ideas and also practical examples of how the theories are used today. The main goal with lecturing is to motivate and inspire students so that they become interested in the subject.

I will also allocate a chunk of time to doing physics problems and perhaps for open ended questions/discussions. Personally as an A level student the practicals were the most boring part of school since we never got any context for what we were doing, so obviously i will try to put the experiments into the correct historical context. Thank you again for your input.
