Fast Simulated Annealing Optimiser

Uncategorized 4 Comments »

http://asa-caltech.sourceforge.net/

I highly recommend this tool for your Optimisation purposes - very efficient code and a good example for learning how to implement Simulated Annealing Algorithm in C. What what inspires me is the approach the coder of the tool (Lester Ingber) has taken to implement the algorithm - well organised structure highlighting the prime benefits of C over Matlab.

New chart for about page

Uncategorized No Comments »

blogChartMain_v2.pngThe reason I tool the about page offline was that it did not accurately reflect the focus of this blog. I have drawn up a new chart that is supposed to replace the old one, and apart from it reflecting some of the topics I write about here I would like it to serve as a general chart that shows how Signal Processing and Machine Learning come together in developing Financial models. Please comment on any addition/alteration that can be made.

Graph plotting tool

Links, Opensource No Comments »

Seriously, Graphviz is such an excellent graph plotting tool.  I have used it on many occasions here and find myself using it more often than Visio.  Might be useful to some who have not come across it before:

Call for papers: What to do when you cannot forecast

Uncategorized 4 Comments »

Nassim Nicholas Taleb is co-editing a special issue of the International Journal of Forecasting with focus on “decision making and planning under low levels of predictability”. The official invite can be found here and while I will not be submitting a paper, I will surely obtain a copy of the issue when it is published.

I have added a few links to my blogroll:

  1. Tom at Neural Market Trends shows how develop AI based financial models using an open source tool called Rapid Miner. He provides a number of tutorials and even has a member’s section where he shares his models through videos and examples. I think this is an excellent way for one to get started developing AI financial models. From what I hear the Rapid Miner tool has a steep learning curve, but Tom alleviates this a great deal through his easy to understand tutorials.
  2. Ali’s blog talks about mostly quant stuff with occasional digressions. I recommend this site for your daily food for thought.
  3. foquant runs a quant blog. He recently developed an SMS order confirmation tool for trading which can be downloaded from the models page at his site. He provides a number of other quant finance models and is always adding newer ones.
  4. Two fish’s blog covers a wide variety of topics ranging from quant finance to ghosts and immigration. Fascinating stuff!
  5. Visit the One Unified Blog for your dose on programming and IT related issues. The blog shares a model for Trade Optimization by Genetic Programming, written for the QuantDeveloper platform.
  6. The Econophysics blog provides a rare blend philosophical issues surrounding quantitative finance and quantitative social science. A must read!

Immune System video

Artificial Immune Systems, Eye Candy No Comments »

I found this excellent video explaining very casually how the Immune System works. I thought it would be a great addition to one of my previous posts “Financial applications of Artificial Immune Systems“. I’ve copied it below for easy view.

Organised chaos

I’ve been very busy over the past few days. I hope to make progress today. Have a look at this clip showing a neural network simulation. “Organised chaos” as the owner puts it.
