finished...??

Well, the thesis is now printed out and at the binders, ready to be picked up and submitted this Friday morning. At the back of my head, I know that this is not the last time I will work on it. I want to submit a paper based on the thesis to a Cognitive Computation journal special issue which has a deadline of 1st November, generate papers out of the thesis and return to it again at viva time. And it's not handed in, yet. An academic's work is never done?

But...

A little celebrating will be done on Friday!

For the moment, the thesis in its submitted form is available at

http://dl.dropbox.com/u/6496211/AnnaJordanousThesis.pdf 

It's a large file (23.8Mb) so I'd like to put it up, chapter by chapter if possible, on academia.edu or similar, and probably link to it on this blog too. But that is to be done another time, let's at least allow myself a day or two off of it!

The loneliness of the long-distance writer... or misery loves company?

I will hand in my PhD thesis this September. It is official. I handed in a form today that says as much.

Right now, two months seems like both an incredibly long time to be refining a document and an incredibly short time to finish everything off satisfactorily. Having spent July intensively writing up my thesis work (then getting ill, then getting back to the intensive write-up), I'm starting to produce something that I feel really proud of, slightly sick of and which continually surprises me with where it takes me, even now that all the data is collected and collated.

What has really surprised me during this time is the little community of 'writer-uppers' and 'finishers' that has developed around me.

I'd expected that these few last months of PhD would be lonely, spent mostly in front of a computer screen. That has turned out to be half true: the computer screen and I have become extremely well acquainted.

But... there seems to be so many people around me who are in the same boat, aiming for that September deadline. Even those not doing PhDs seem to be getting into the act, with contracts finishing in September, new jobs starting then, gig calendars starting to look towards October, etc. If I'm stressing about a particular problem in the thesis, or going slightly numb from trying to turn a dry set of numbers into some fascinating facts, then I don't have far to look before I find someone who can emphathise, or someone for a tea break.

So despite the title of this blog post, the tail end of the PhD tale isn't turning out to be like the loneliness of the long distance runner, bravely struggling on alone in the face of all adversity and difficulty. In all honesty it hasn't been that miserable either - in fact on occasion it has even been... almost... enjoyable! (I may have to keep reminding myself of that sometimes in the near future though?)

So, enough procrastination - it's back to the dry sets of numbers then. 2 months and counting till hand-in and the start of the next challenge.

The perils of word counts in LaTeX

I'm currently writing up my thesis. I am writing it in LaTeX, which for the uninitiated means that rather than writing it in Word or similar, I write it in a text file and include lots of formatting commands around the thesis to say `this bit should be emphasised' or `this bit is a subsection', then LaTeX produces a pretty pdf file from my text file.

Like any self-respecting numbers girl, I like to keep a watch on how many words I have written that day, and in total. Although I don't have a word limit to adhere to, hitting a good word count for a day makes me feel like I've done good work, even if a lot of it gets cut later...

For a while now I've been dubious about the word counter I've been using: the inbuilt Statistics word counter in TeXShop, which works using detex | wc -w , or in plain English, it strips the thesis file of all the formatting commands and then counts the number of words left. According to this word counter, I have 61138 words, but I've noticed that this total tends to fluctuate: there have been days where I've written a lot and have ended up with less words than I started with.

Trying some alternatives out:

• texcount *.tex: 60239 in text + 1457 in headers + 2469 in captions = 64165
• ps2ascii thesis.pdf | wc -w: 83415 (but this includes the bibliography which is currently 7686 words and any appendices text) 
• copying and pasting the text into OpenOffice: 75222
• copying and pasting the text into Word: 74664
• copying and pasting the text into TextWrangler (a Mac text editor): 74093

So I've anything between 61000 and 83000 words. TeXShop's statistics is instant but inaccurate. Texcount takes about 30 seconds to process then a quick calculation has to be done. ps2ascii also takes a little while and doesn't separate the thesis text from the bibliography/appendices. Copying and pasting, sadly, looks the most accurate (though now I have no idea how many words I've actually got...)

What I mostly want is a tool that measures progress very quickly, for some motivation - so I'll probably stick with TeXShop's Statistics or use texcount, after all of that!

As my housemate says, however,

it doesn't really matter if its 60 or 80 or 100,000 words, just finish it!

Right then: enough procrastination, back to the writing...

Looking for survey participants - no specialist knowledge required - the more participants, the better!

I'm running an online survey for my PhD research, about computer systems that improvise jazz. The survey gives you some brief information on four different systems and some demos of their music, and asks you to think about how creative the systems are.

I'd really like a spread of opinions on this - from musicians to non-musicians, people who improvise jazz to people who don't, from computer programmers through to people who have the ability to break computers just by looking at them (!) - and I'm after as many participants for the survey as possible... so...

Please could you help me by doing my survey? The survey is at this link:

http://edu.surveygizmo.com/s3/547547/Computer-systems-that-improvise-jazz-How-creative-are-they

So far it's taken people around 15-30 mins to do. People are saying that they've found it interesting and that even if they haven't known about computer music or jazz improvisation, they have been able to take part in the survey.

Sadly I can offer no payment/sweets/etc for doing the survey - all I can offer you is a warm happy glow for helping a PhD student in need, or if that isn't enough, the chance to procrastinate for a bit and take a break, whilst doing something research-related. Also it's fun to see what music the computer systems can come up with and how they do it, if you're interested in this sort of thing? Thank you in advance, I really appreciate people's help!

Results will be published in my PhD thesis (due for completion September 2011) and I may summarise the results briefly in a blog post here too.

A 'marks' sheet for evaluating how creative a computer system is

My research looks at how best to evaluate computational creativity systems - how creative is this computer program?

Computational creativity is when a piece of software acts in a way which would be perceived as creative if seen in a person.

From this research I have produced a sheet which can be used to evaluate and assess how creative a creative system is. It helps you judge the creativity of the computer program on several different aspects and components (see this previous post on identifying building blocks of creativity).

Here is the sheet.

Feel free to go ahead and use it, let me know how you get on. To cite this, please refer to my PhD thesis (title, more details and papers on this at my academic web site).

If you want even more detail, then you only have to wait till my doctoral thesis is ready in September 2011, or else please contact me (contact details on my web site) - I would love your feedback.

Update: Building blocks of creativity

There has been a lot of useful feedback from my previous post reporting on my empirically-derived definition of creativity.

As a result, and after some more work that I have done, I've updated the results.

These factors form 'building blocks' of creativity - they contribute to the overall idea of what creativity is. This could also be thought of as an ontology of creativity - a collection of information relating to the nature of creativity.

                           Creativity is...

To expand on these 14 factors, here is a diagram with a little more detail in each factor. (Click on the diagram to enlarge it)

Depending on what creative domain you are looking at (e.g. art, music, problem solving, proof generation, language use, design etc.) some of these factors will be more important than others.

From the results of a survey on musical improvisation, this is a breakdown of which factors are more important (and less so) in this type of creativity:

The importance of different components of creativity, in the context of creative musical improvisation. This illustrates the results of a survey of 34 people, spanning a variety of musical backgrounds from novice to professional expert. Note that some factors are considered to have some negative influence on creativity as well as a positive influence, e.g. Domain Competence.

The next step in this work is to use the survey data and above results to evaluate and compare a number of music improvisation systems, to explore which are more creative than others and why. Results coming soon...

Today I defined creativity... Here's the definition

Here are the results of some work that I have been doing to capture in words a definition of creativity, as we understand and use the word 'creativity'.


[Ok so the timing in the title of this blog post is perhaps a little misleading... Rome wasn't built in a day and I didn't do this work all in one day... ]

The idea behind this work is that when we talk about what creativity is, certain words keep on cropping up as they are strongly associated with creativity. If we can capture those words, then they will collectively form a definition of creativity.

What I have done is to analyse discussions of creativity, to find what words appear significantly more often in such discussions (compared to discussions on unrelated topics). This gave me a list of 374 words. I've condensed this list by grouping words together that mean similar things and analysing the results, identifying 20 themes in the words.

Here are my results: 20 aspects of creativity. I propose that the combination of these 20 aspects collectively form a definition of creativity.

What do you think?
