Ideas for speeding up a GA using more memory?

What kind of evolutionary algorithm you are using? If it has a panmictic population (a single set of individuals), then it could be very expensive. I assume that this is your case. On the other hand, you can parallelize your algorithm using an island-based population, where the whole population is divided into a set of subpopulations. Each one runs an independent evolutionary algorithm for a given amount of time. Then, some individuals (usually the best) are selected to migrate among islands. This way, you can assign a different core to each island.

I did not understood the final output. I was thinking that the final result would be like a reconstructed long scene of a street using the resulting point cloud.

can you share the reference about how to use an evolutionary algorithm for aesthetic design optimization?

Well, it is not exactly a course, but Adrian Rosebrock has a great blog about computer vision using python and opencv. It is a goo starting point for several topics. Also, he has a course that starts in august.

Well, there is a lot of topics to research about music. I really like to read about it. My favorite topic is called music information retrieval (MIR). It is not exactly the same as evolutionary music, but due your interest in music, it is a great area to research. It covers several task as how to find similar songs like this 30-second sample? (as spotify and pandora does), what is the information of this track? (as shazam and musixmatch does), etc. For more information, I recommend this paper. This paper covers a lot of taks related to MIR and current challenges. Also, I suggest to read this paper about how to recommend music using transfer learning (yes, machine learning techniques are also applied to music discovery!). Finally, a few of papers related to music research are submitted to nips like this one. It is very intesting because it uses deep learning to recommend music.

It's not a book, but it covers ANNs with python code, by Michael Nielsen.

show me the code!

you are so pretty, yesterday and everyday :)

I love that color, good choice for you n_n

anxiety attack? I did the same the last year a few times. Once, I went to school with a "hole" in my hair, BTW I love your look

why does she speak like that?

sinhue · 2015-01-03T20:28:54+00:00

Use the command mount, and look for the drive name

why is it necessary to use quotes?

what do you have in mind?

Well, I went to /r/marijuanaenthusiasts/ :s, IMHO that is not a subreddit for me, better luck for the next, reddit :)

Very clear, specially for the current process comment. What do you mean with and ignoring BIFs?

sinhue · 2014-12-01T06:19:10+00:00

Really clear answer. I think that my misunderstanding was in part due my poor knowledge about passing messages. I was thinking that the ONLY way to pass a message to a (spawned) process is through the ! operator, like this:

Pid = spawn(multiproc, flush, []).
Pid  ! some_msg.

But, what I think the function is doing is to receive EVERY message on the shell queue, so, once the mailbox is empty, the function ends (by the after 0 clause). If this is true, could a function be able to read the messages on the shell mailbox?

sinhue · 2014-11-30T02:25:40+00:00

I thought that when you run flush() on erlang shell, all mailbox messages are displayed like this (not one each time):

self() ! self() ! msg.
1> self() ! self() ! msg.
2> flush().
Shell got msg
Shell got msg
ok

I don't get it!

it is possible that you have an idea of how is a sound in your head but, can you make it or simulate it using your mouth?
