Do you see patterns in Random Walks?

Quote from Lornz:

Neurogenesis is better induced by performing aerobic exercise which requires balance; skateboarding comes to mind.

Why would I want to harm another being?

Yoga is better.
 
Quote from RCG Trader:

Interesting, Asimov founded a concept called psychohistory that basically used math to predict the trajectory of large groups of people under certain situations. Is this what you do?

Yes, that is what I do.

cheers,
MAESTRO

P.S. I LOVE ASIMOV!!! I have read all of his works. I have his entire collection on my Kindle!
 
I have been thinking a lot lately about Thomas Bayes and his remarkable discovery. It is hard to believe that someone in 1700s could have such a vision! It has been forgotten for over 200 years and now there is even a brand new branch of Artificial Intelligence that is based entirely on Bayes's Theorem. Since I have been implementing this approach lately in my own work quite successfully I have decided to dig a bit more in this direction. It is quite fascinating! I also have realized that there is no good portrait of Reverend Thomas Bayes. So, I have decided to create my own. It took me about a month and a lot of reference images to create it, but I am glad I finally finished it. I used to paint a lot, however in recent years I was too busy and did not have time for art; not good! I am glad that I took time to make this portrait. Please let me know what you think.

Cheers,
MAESTRO

P.S. According to a research I found online 97% of all the people who were exposed to Bayes's Theorem still do not understand it entirely and cannot implement it in their work properly.

Then you are aware that Asimov may have been a psychohistorian himself, and we are in the final stages of the "Galactic Empire". That said, how can traders, most of whom sense something is amiss without knowing exactly what, benefit from what you are trying to convey?

In other words, what do we need to know, and where do we start?

Question:

How many of you, guys really and truly understand the Bayes’ Theorem? How many can say that they easily could implement it in any situation? I have a strong suggestion: please read this article.

There is much more to it that meets the eye!

Huh... Baye's Theorem...?! Well now you've given me something to think about. I haven't read the entire thread... Do you apply this to trading...?

Good portrait... :)
 
Did you paint that? That's really good, good to have a hobby outside the computer.
I read about Bayes theorem in my probability book (http://www.dartmouth.edu/~chance/teaching_aids/books_articles/probability_book/book.html, they put on GNU license so anyone can download and study). The examples I've seen in the book and a couple other sources, they always use the example of breast cancer. The formal definition trips me up. Here's my simplified template from the example:
1) there is an actual percentage of the population who have it
2) the test has an error of some amount
3) of those who get a positive result, take out the % of: (actual % population that does not have it * test error)
4) this gives you: of those who tested positive, how many actually have it
So, even if you get a positive test result, it's a less than one probability, and the probability is reduced more than just the test error rate, but the number of results that are false positives.
I haven't found people to discuss it with to learn more interactively, like you say most people haven't been exposed to or understand it.
 
Quote from MAESTRO:

There are at least three distinct forms of uncertainty:

1. Ignorance. The limits of our knowledge lead us to be uncertain about many things. Does our poker opponent have a flush or is she bluffing?

2. Physical randomness or indeterminism. Even if we know everything that we might care to investigate about a coin and how we impart spin to it when we toss it, there will remain an inescapable degree of uncertainty about whether it will land heads or tails when we toss it. A die-hard determinist might claim otherwise, that some unimagined amount of detailed investigation might someday reveal which way the coin will fall; but such a view is for the foreseeable future a mere act of scientistic faith. We are all practical indeterminists.

3. Vagueness. Many of the predicates we employ appear to be vague. It is often unclear whether to classify a dog as a spaniel or not, a human as brave or not, a thought as knowledge or opinion.

Bayesianism is the philosophy that asserts that in order to understand human opinion as it ought to be, constrained by ignorance and uncertainty; the probability calculus is the single most important tool for representing appropriate strengths of belief

MAESTRO,

The trouble with weather forecasting is that it's right too often for us to ignore it and wrong too often for us to rely on it.
