Handling default options in Matlab

Patrick Pletscher — Thu, 29 Sep 2011 19:57:41 +0000

I have found the following script useful for dealing with options in Matlab scripts.

function myfunction(input, options)

options_default = defaultOptions();
if (nargin >= 2)
    options = processOptions(options, options_default);
else
    options = options_default;
end

% here comes the logic of myfunction which might access some of the options

end

function options = defaultOptions()

options = [];
options.max_iter = 200;
options.lambda = 1.0;

end % defaultOptions

            view raw
            myfunction.m

options = optionsDefault;
if (isstruct(optionsInput))
    fields = fieldnames(optionsInput);
    for i=1:length(fields)
        if (~isstruct(getfield(optionsInput, fields{i})))
            options = setfield(options, fields{i}, getfield(optionsInput, fields{i}));
        else
            temp = processOptions(getfield(optionsInput, fields{i}), ...
                            getfield(options, fields{i}) );
            options = setfield(options, fields{i}, temp);
        end
    end
end

end % processOptions

I uploaded a graph cut MEX wrapper to the software section of this website.

In Boston and Florida

Patrick Pletscher — Tue, 07 Apr 2009 11:30:28 +0000

I’m currently in Boston and will stay here till the end of the week. Next week, I’ll be attending the Snowbird Learning Workshop and AISTATS in Clearwater Beach, Florida. If you want to meet somewhere on the way, drop me a line!

stroll: Structured Output Learning Library

Patrick Pletscher — Wed, 01 Apr 2009 12:50:39 +0000

I just released the first publicly available version of stroll, a library for structured output learning. stroll amongst other training algorithms also includes the spanning tree algorithms that I’ll be presenting in two weeks at AISTATS 09 in Clearwater, Florida. To learn more about the software, see the project page.

Freshman introduction: Why math?

Patrick Pletscher — Thu, 11 Sep 2008 11:36:14 +0000

Today, I gave a small presentation to the first year students here at ETH to tell them why I personally think that learning about math in the first years is important. I decided to upload the slides, you can find them here; if this is helpful in order to get at least one person interested in calculus, algebra etc. than my goal is achieved! The slides are in German.

Syncing contacts within Mozilla Thunderbird

Patrick Pletscher — Sun, 31 Aug 2008 10:21:15 +0000

I’m nowadays working on three different machines and thus also send emails from all of them. The problem is that I did not find any way to sync my address book in Mozilla Thunderbird across the three workstations, so every now and then I had to be creative to find that one email address. Not anymore! Synckolab came to the rescue, so far this works painlessly and only needs an IMAP folder.

Radford Neal’s blog

Patrick Pletscher — Wed, 20 Aug 2008 10:52:20 +0000

I today found the new blog of Radford Neal. While I have been reading some blogs in the machine learning /statistics community for some time, like for example Hal Daume’s blog or John Langford’s blog, I think Radford Neal’s blog has the potential of being a great alternative to these blogs for two reasons: he is a very senior person and he is more the stats guy, whereas most other blogs are probably on the machine learning side of things.

Heading off to CVPR

Patrick Pletscher — Sat, 21 Jun 2008 20:29:07 +0000

I’ll be at CVPR in Alaska next week. Looking forward to meet a bunch of people there that I haven’t met in a while.

Photo gallery

Patrick Pletscher — Sun, 01 Jun 2008 11:14:35 +0000

I finally found some time to upload some of the more recent photos I took.

I use zenphoto as my gallery software and I find it a rather neat piece of code.

Update: Because of several issues I removed the gallery again. I guess after all it wasn’t such a great software.

Off to San Francisco

Patrick Pletscher — Wed, 19 Mar 2008 21:10:06 +0000

Will spend Easter and the week thereafter in the Bay area and come back to Switzerland through San Diego and Las Vegas, where I will also spend some time.
