A Tutorial on Polynomial Regression through Linear Algebra

Tags

Algorithms, Linear Algebra, Mathematics, Matrices, Polynomial Regression, Regression, tools, tutorials

If you are a chemist, biodesigner, or a researcher working in other fields, eventually you may need to fit a paired data set to a polynomial regression model. You could use software to do that, or build your own solution. This tutorial is aimed at those interested in the latter. Access it now at

http://www.minerazzi.com/tutorials/polynomial-regression-tutorial.pdf

Three different methods for implementing polynomial regression are described. Teachers and students might benefit from the tutorial since the calculations can be done with a spreadsheet software like Excel, by writing a computer program, or with a programmable calculator.

72 Binary Similarity Measures

We have expanded the number of similarity measures that our Binary Similarity Calculator computes from 30 to 72 (and counting…)

Same measures with different names have been consolidated into a single record, and different measures with same name have been enumerated as necessary.

These similarity coefficients have many applications across disciplines: from bioinformatics to chemistry, chemometrics, statistics, data mining, information retrieval, marketing research, etc.

The tool is available at

http://www.minerazzi.com/tools/similarity/binary-similarity-calculator.php

We have also included the new similarity measures proposed by Consonni & Todeschini (2012), and Todeschini, et al (2012).

Our Tutorial on Distance and Similarity was also updated, accordingly. Check it out at

A Step Closer to Mind Retrieval

We are getting closer to Mind Retrieval. The implications of being able to mine the brain are obvious for all sciences, in addition to homeland security, law and order, marketing research, etc.

I got last night this news, “Scientists map brain’s ‘thesaurus’ to help decode inner thoughts

Scientists at the University of California, Berkeley, have taken a step in that direction by building a “semantic atlas” that shows in vivid colors and multiple dimensions how the human brain organizes language. The atlas identifies brain areas that respond to words that have similar meanings

Last year I mentioned that we are getting close to Mind Retrieval.

That post was a reminder of a previous 2010 interview by Nuno Valenzuela, a visionary SEM from Spain. Great guy.

I met Nuno back in 2007 when I was invited to present at a Madrid Search Engine Congress (OJOBuscador) on Latent Semantic Indexing (LSI).
