Abstract: 

·         Linear regression plays a big part in the everyday life of a data analyst, but the results are not always satisfactory. What if you could drastically improve prediction accuracy in your regression with a new model that handles missing values, interactions, AND nonlinearities in your data?

·         Instead of proceeding with a mediocre analysis, join us for this presentation, which will show you how MARS non-linear regression, TreeNet gradient boosting, and Random Forests can take your regression model to the next level with modern algorithms designed to expertly handle your modeling woes.

·         With these state-of-the-art techniques, you’ll boost model performance without stumbling over confusing coefficients or problematic p-values!

*****************

Brain research is rapidly advancing with the application of big data
technology to neuroscience as can be seen in major international
initiatives in the US, Europe and Asia.  BIH'15 reflects that brain
informatics has emerged as a distinct field and crosses the
disciplines of neuroscience, cognitive science, computer science,
signal processing, and neuroimaging technologies as well as data
science. Following the success of past conferences in this series,
BIH'15 will take place at Imperial College London, in UK, gathers the
researchers from major international brain research projects, and
plans an industrial exhibition.

BIH'15 draws special attention to informatics for brain science, human
behavior and brain health.  BIH'15 will address big data approaches to
both the brain and behaviour, with a strong emphasis on emerging
trends of big data analysis and management technology for BI, active
media technology in behavior learning, and real-world applications for
brain and mental health.

BIH'15 welcomes paper submissions (full paper and abstract
submissions).  Both research and application papers are solicited.
All submitted papers will be reviewed on the basis of technical
quality, relevance, significance and clarity.  Accepted full papers
will be included in the proceedings by Springer LNCS/LNAI.

Tutorial, Satellite symposium (workshop) and Special-Session proposals
and Industry/Demo-Track papers are also welcome.

the series of LNCS/LNAI.

TYPE-II (Abstract Submissions; Submission Deadline: May 20, 2015):

Abstracts have a word limit of 500 words.  Experimental research is
particularly welcome.  Accepted abstract submissions will be included
in the conference program, and will be published as a single,
collective proceedings volume.

Title: Include in the title of the abstract all words critical for a
subject index. Write your title in sentence case (first letter is
capitalized; remaining letters are lower case). Do not bold or
italicize your full title.

Author: List all authors who contributed to the work discussed in the
abstract. The presenting author must be listed in the first author
slot of the list. Be prepared to submit contact information as well as
conflict of interest information for each author listed.

Abstract: Enter the body of the abstract and attach any applicable
graphic files or tables here. Do not re-enter the title, author,
support, or other information that is collected in other steps of the
submission form.

Presentation Preference: Authors may select from three presentation
formats when submitting an abstract: "poster only,”, “talk
preferred" or "no preference." The “talk preferred" selection
indicates that you would like to give a talk, but will accept a poster
format if necessary. Marking "poster only" indicates that you would
not like to be considered for an oral-presentation session. Selecting
"no preference" indicates the author's willingness to be placed in the
best format for the program.

Each paper or abstract requires one sponsoring attendee (i.e. someone
who registered and is attending the conference). A single attendee can
not sponsor more than two abstracts or papers.

Oral presentations will be selected from both full length papers and
abstracts.

*** Post-Conference Journal Publication ***

The BIH conferences have the formal ties with Brain Informatics
journal (Springer, http://www.springer.com/40708). Accepted papers
from the conference, including their Best Paper Award papers, will be
expended and revised for possible inclusion in the Brain Informatics
journal each year.  It is fully sponsored and no any
article-processing fee charged for BIH authors.

Selected submissions will be considered for publication in special
issues of international journals after their papers are extended to a
full-length paper and pass a review process.  More information can be
found at http://www.bih-amt.com/publications/

*** Topics and Areas ***

Please find the topics and areas of interest of the 2015 International
Conference on Brain Informatics and Health (BIH'15)
at http://www.bih-amt.com/call-for-papers/topics/

*** AMT'15 Session ***

The advance of wearable sensor technology makes the monitoring of
human behavior and life style becomes feasible. This development gives
the active media technology a new dimension which is more closely
related to the healthcare and cognitive studies. Following the success
of past conferences in this series, AMT'15 will be jointly held with
BIH’15 as a special session.

Re: I'm trying to install S-Plus 6.1 so it works with Excel 2013

YC,
I think that your emails are not going to the list, just to me. You will need to use "reply all" in your email client if you want to post to the list.
Cheers!

Dear Ones:
  The commercial versions of S and R all have the ability to deal with the MS Access files and MS Excel files. SAS and SPSS do also have the ability. Revolution R is a better way to deal with Excel file. If you use the S+ 6.0, it could not deal
with the latest Excel file such as xx.xlsx but may only for the MS  Excel 2003 or before. Revolution R is a better candidate for your choice because of the Recolution R(I love to call it R+) use the same core program S which is the original of S+ but with better system cointegration and memory management with parallel computing ability.

With all due respect, Franklin (the original poster) is wanting to use Excel with S-Plus. In that context, speed and memory management is the least of his concerns.

I did try one in 8 or 9 years ago. the result shows the R has better memory management and system integration on Windows platform. So R can do the program in several seconds, but the S-plus 8.0 has to finish in hours. I suggest you transform from S-plus to R or the commercial version of R such as Revolution R. Revolution R provide free use for academic users and it has the ability to management large-scale data sets like SAS.

thanks for response about median question!

I want to thank all the people on the list who very generously responded 
to my median question.

For those who are interested, here is my question again and a summary of 
responses:

Question:  If X and Y are symmetric and independent, then is it true 
that Med(X+Y) = Med(X) + Med(Y)?

First of all, the answer is always Yes!

A number of people noted that if both X and Y have finite means and X+Y 
is symmetric, then

X+Y has a finite mean, all the means are equal to their medians, and so

Med(X+Y) = E(X+Y) = EX + EY = med(X) + med(Y).

The only thing missing in this special case where X and Y have finite 
means, is a proof of the supposition

that X+Y is symmetric.  That proof I found at the following link:

http://stats.stackexchange.com/questions/95002/the-sum-of-two-symmetric-random-variables-is-symmetric

Part 3 presents a simple and clear proof that uses convolution as well 
as the symmetry and independence of X and Y.

This proof assumes that the means of X and Y exist, but it is very clear 
that the argument goes through even if the means do not

exit and are replaced by medians.  So, for example, If X is Cauchy and Y 
is normal and X and Y are independent, then it is still true that

med(X+Y) = med(X) + med(Y).

Again, thanks for all the responses.

Cheers,

Bob Sherman

Trying to install S-Plus 6.1 so it works with Excel 2013

I want to thank everyone who offered suggestions in response to my trouble getting S+ and Excel versions to work together.

 

There are more statistical packages than I realized, as the Ph.D.’s in the group pointed out. I will learn more about R, in particular its ability to execute the same procedures that I performed in S+. Apparently, R has some advanced features or extensions that take the place of the S+ GUI and environment. Learning about R is more of a long-term objective.

 

My immediate objective is to achieve the same capabilities with S+ and Excel 2013 that I had in S+ and Excel 2003. S+ 6.1 doesn’t recognize the new Excel and doesn’t know how to access its functionality. S+’s integration with Excel included reading XLS files, an Excel Add-In application, an S-Plus Link Wizard and more. Maybe that’s a lost cause, but any hope of getting both of them to work together is more of a software installation issue related to Excel revisions. I’ll probably seek help for that with a newsgroup that specializes in Excel.

 

Thanks again,

 

Franklin Neubauer

I'm trying to install S-Plus 6.1 so it works with Excel 2013

Does anyone have experience installing S-Plus 6.1 and getting it to work properly with new versions of Excel?

 

Since I will lose my old computer, I removed my copy of S-Plus and tried to install it on my new PC that runs Microsoft Office 2013.  I got error messages from Microsoft Office, which is understandable since Office is much newer than S-Plus 6.1. I expect that S-Plus could be set up to work with the new Excel, but I don’t know enough about new versions of Excel or about Windows to accomplish that.

 

I plan to reinstall S-Plus. However, it will be a big handicap if S-Plus can’t read XLS files. Has anyone figured out how to get the old S-Plus to work with the new Excel.

 

If I learn of useful solutions, I’ll try to document them for the group. Thank you in advance.

CFP "Transfer Learning" - Special Session IWANN

*** Apologies for cross posting ***

 

CALL FOR PAPERS

Special Session on Transfer Learning

International Work Conference on Artificial Neural Networks

June 10 - 12, 2015, Palma de Mallorca, Spain

 

Transfer Learning (TL) aims to transfer knowledge acquired in one problem, the source problem, onto another problem, the target problem, dispensing with the bottom-up construction of the target model. The TL approach has gained significant interest in the Machine Learning (ML) community since it paves the way to devise intelligent learning models that can easily be tailored to many different domains of applicability.
The following aspects have recently contributed to the emergence of TL:

-          Generalization Theory: TL often produces algorithms with good generalization capability for different problems;

-          Efficient TL algorithms: TL provides learning models that can be applied with far less computational effort than standard ML methods;

-          Unlabeled data: TL can be advantageous since unlabeled data can have severe implications in some fields of research, such as in the biomedical field.

 The topics of this special session are:

·       Big Data with Deep Neural Networks;

·       Generalization Bounds;

·       Domain Adaptation or Covariate Shift;

·       Algorithms for TL;

·       New advancements in TL;

·       Real-world applications.

 

Paper Submission Deadline: February 6th, 2015

question about a the median of a sum of random variables

Hi all,

I know that in general the median of a sum of random variables is not 
equal to the sum of the individual medians.  For example, Romano and 
Siegel have an example in their counterexamples book where the median of 
a sum of two independent identically distributed exponential random 
variables is not equal to the sum of the medians of the individual 
exponentials.

However, I am "sure" that it must be true that if X and Y are 
independent AND symmetric, then X+Y is symmetric and in addition the 
med(X+Y) = med(X)+med(Y).  I've constructed many discrete and continuous 
examples where this is true.  However, I have not been able to prove 
this in general myself or find a reference for this.

Does anyone on the list know of a reference or a counterexample?

Many thanks!
