LJ interests meme

Happy birthday, darkdragoness93!

From masteralida:

Scan my interest list and pick out the one that seems the most odd to you.
I'll explain it.
Then you post this in your journal so other people can ask you about your interests.

Me too.

I meant to say "I'm curious about that too." It sounds like something I ought to be able to translate from my knowledge of scientfic Greek roots, but it's not immediately apparent.

Arabidopsis and bioinformatics
Me too.
I meant to say "I'm curious about that too." It sounds like something I ought to be able to translate from my knowledge of scientfic Greek roots, but it's not immediately apparent.

Arabidopsis thaliana, or A. t. for short, is a model organism that we study as an application of functional genomics. As the Wikipedia says:
Functional genomics is a field of molecular biology that is attempting to make use of the vast wealth of data produced by genome sequencing projects to describe genome function. Functional genomics uses high-throuput techniques like DNA microarrays, proteomics, metabolomics and mutation analysis to describe the function and interactions of genes.

Because of the large quantity of data and the desire to be able to find patterns and predict gene functions and interactions bioinformatics is crucial to this type of analysis. Comparative genomic analyses can also held determine gene function.

Imagine what we could do if we understood how genes turn one another on and off: identify deletions (knockouts) that result in higher-yield crops; interrupt the gene pathway leading from a cancer gene to the actual growth and spread of cancer; use drugs to activate the immune systems of farm animals, pets, and humans; etc.

This short essay I wrote last summer outlines some of the applications and discusses why I have chosen to study bioinformatics.

Arabidopsis: the Leek of KDD
Arabidopsis thaliana, the Thale Cress or Mouse-Ear Cress, is the white lab mouse of the plant sciences world.
a small flowering plant related to cabbage and mustard, [it] is one of the model organisms for studying plant sciences, including genetics and plant development. Similarly as mouse and fruit fly (Drosophila) are used as model organisms to understand human biology, Arabidopsis thaliana is used to study agronomic crops.

Arabidopsis is the "national plant" of KDD, and it is used to commemorate the date of its founding, 31 July. I've said on occasion that we should wear sprigs of it then, as the Welsh wear leeks on St. Davy's Day:

Your majesty says very true: if your majesties is
remembered of it, the Welshmen did good service in a
garden where leeks did grow, wearing leeks in their
Monmouth caps; which, your majesty know, to this
hour is an honourable badge of the service; and I do
believe your majesty takes no scorn to wear the leek
upon Saint Tavy's day.
I wear it for a memorable honour;
For I am Welsh, you know, good countryman.

A better answer
This response to angharad gives a more cogent explanation.

Aside from computer terms and fandom references that may be unfamiliar to me, yet undoubtedly have prosaic explanatons, only one of your interests really puzzles me: ecumenicism. How does this word apply to you, and why do ecumenical things interest you?

i was putting together a 50 states puzzle from my childhood the other day. guess which one state was missing.

I'd like to know more about "decision theory." :)
Jan. 27th, 2005 03:54 am (UTC)
Decision theory
Decision making is the cognitive process of selecting a course of action from among multiple alternatives. Common examples include shopping, deciding what to eat, and deciding who or what to vote for in an election or referendum.
    -Wikipedia (2005)

The specific flavor of "decision theory" that I study is called decision analysis:
Decision analysis (DA) is the discipline comprising the philosophy, theory, methodology, and professional practice necessary to address important decisions in a formal manner. Decision analysis includes many procedures, methods, and tools for identifying, clearly representing, and formally assessing the important aspects of a decision situation, for computing the recommended course of action by applying the maximum expected utility action axiom to a well-formed representation of the decision, and for translating the formal representation of a decision and its corresponding recommendation into insight for the decision-maker and other decision participants.

The term decision analysis was coined in 1964 by Ronald A. Howard, who since then, as a professor at Stanford University, has been instrumental in developing much of the practice and professional application of DA.

    -Wikipedia (2005)

I hope this answers your question (it's probably more than you wanted to know, but I do like talking about this subject :-D).

"but I do like talking about this subject" ?
Um, sweetie, you haven't talked about it.

You just copied text from two Wikipedia entries.

Or did you write the text you copied?

Re: "but I do like talking about this subject" ?
Heh... it's cited, hokay?
<MJ>Quit pressurin' meee...</MJ>

Seriously, the above is almost identical to the textbook definition that's in Russell and Norvig 2e, hence in their slides for decision theory in AI, hence in mine...

But what would you like to know?
I'm supposedly notorious for being unable to distinguish between a lay explanation and an "esoteric" one, whatever that means.

Well, partly, that's the difference between calling a spade a "spade" and calling it a "uni-pronged agricultural implement". (^_^)
