Hope

After around a month of hopelessness, I am working on my thesis again. It turns out that there are still the possibilities of getting a D or just an incomplete grade. Thanks would have to go to my mom who intervened and talked with my teacher to ask about my (our) options.

The revised neural network design, now multi-layer:
Revised artificial neural network design

I just hope things are still going well in the other classes I am taking. Are they? I really do not know.

Not graduating on time

So I will not be able to graduate on March. I am failing my thesis subject (CS197), for which I have not been submitting requirements prior the submission of my new topic proposal. I got zero after zero for the individual requirements, until it just did not make sense to submit succeeding requirements anymore. Maybe it could still have worked out and I made the mistake of deciding too early, but what is done now is done already anyway.

The first thought I had when I realized how grave the situation has become? “Finally, I learn my lesson.” This, in some way, is a good thing. The succeeding thoughts are not as positive: how to break the news to my parents, how to soften the blow of the late graduation by not having my parents pay for tuition and not touching personal savings, what kind of job I really want to have, how badly I messed up that I will be limited to some extent by the fact that I am still not done with college.

I realize still that all this is still worth it, as I am working on a thesis that I respect and that hopefully can be a place to work from so that I can find a job that I enjoy. So what happens to me now? I go on with school, become employed from March until the end of May, graduate on May, then work from there. And sometime before the end of February, I have to talk with my department, the Office of Admission and Aid (OAA), and my parents.

Thanks for the support, and sorry.

Some flaws in the stock price movement neural network

I mentioned in a previous blog post that I am aware of some major flaws in my stock price movement neural network project last semester. Following are among the things that I intend to fix in my thesis:

  1. The system only makes use of two observed stock market trends. Although this does not make the use of a neural network invalid, the addition of more nodes in the hidden layer should give better results.
  2. The system actually makes decisions based on statistically incorrect data-processing. Varying numbers of combinations of parameters were used for each trend, with each combination assigned one node in the neural network. Because these nodes are then treated equally, a trend with a larger number of nodes assigned may still have a larger weight on the decision of the neural network than one that actually gives better results.
  3. The possibility of two levels of decision-making has not yet been explored.

I actually typed these down for someone who wanted to take a look at the paper. And, like I told her, the proposal is where I formally criticize everything I did. Haha!

Prediction of stock price movements through an artificial neural network

For my Computer Simulations (CS158) class last semester, I worked on an artificial neural network that allows more precise predictions of stock price movements. The project passes for a regular school project, I believe, but I have decided to continue working on it for my thesis. Haha, I am glad Sir Paulito Palmes agreed to be my thesis adviser despite the very late submissions and lots of non-submissions I had for his class.

Uploaded here is the paper I submitted. The actual code is messy, and I think I need elaborate on the neural network framework I used for the project more. I am aware of a number of limitations and invalidities, which I will most probably type up here sometime, but I have to say that, even at this point, the project is the coolest work that I have ever done.
