Confessions of a researchaholic

Sharing publications

Filed under: Real — liyiwei @ 11:21 am

Every time I see people listing publications on their websites without linking to the papers or videos, I hear they say: I am here to show off my publications and I do not really care whether you can access the papers. (Or, in a slightly more excusable scenario: I am too weak to not bow to the publisher request of withholding preprints online for 1 year. BTW this is why I do not submit to CGF.)

Best practice: create a public GitHub repo/page to share all paper information (abstract, pdf, video, code, etc.), so that all co-authors can edit and the search engines can index. (I am doing this for all my recent papers.)

Computer science publication model

Filed under: Real — liyiwei @ 3:57 pm

If you need to try out a method, which you do first: (1) read and implement papers, (2) compile and run open source codes.

The peer review model for scientific publications has not changed much for centuries. It is about to, at least for computer science and especially for machine learning (e.g., where sharing and reproduction is much easier than other science and engineering disciplines.

I was searching my email box about the “fence” of the house and surprised to find out how many paper reviews contain the phrase “on the fence”.

Objective perception of subjective reality

A core skill, in art, science, or even life, is the ability and willingness to objectively perceive subjective reality.

Notice the swap of the two adjectives. Supposedly, perception is subjective and reality is objective. However, that is a fixed given condition. Our bodies and brains act like filters, so reality is always subjective. What we can strive for is objective perception and depiction of the (given) subjective reality.

For example, in drawing, one has to perceive what is really out there, which can vary depending on the individual subjectivity, in the physical world, in the memory, or in the imagination.

In deriving a math proof or following a scientific argument, one has to rely on what is assumed to be true (axioms, theorems, conjectures) which are subjective by nature.

Comparing deadlines of various conferences I have submitted to

SIGGRAPH deadline: you are completely dead!

CHI/UIST deadline: you are really dead!

CVPR deadline: you are half dead and can continue to submit supplementary materials like a zombie.

Academic lineage

My academic lineage traces to Jung and Freud instead of Gauss, Laplace, Newton, or Leibniz.
I guess this partially explains my research interest and mentoring style.

Practice shading a color pencil cylinder

Hatching is a core technique to convey shading and texture in sketching.
I have hatched algorithmically so it is only fitting for me to practice manually as well.
This exercise also gave me research ideas which I would not be able to conceive without the artist perspective.

Commonalities between research and drawing

Both require sighting novel and interesting ideas or scenes. Without this important first step, the rest will fail even with perfect execution.

The author needs to be patient and persevering to complete a sufficiently challenging work without ever giving up.

Strong objectivity is required to help us see the reality without being blinded or obscured by our biases and wishes.

Drawing is one of the few activities, aside from SIGGAPH deadline, which can enter me into the zone.

Mischiefs with paper author names

Filed under: Real — liyiwei @ 4:42 pm

Be a sole author, multiple times.

Add native author names.

Sneak behind other more senior/established collaborators to become the last author.

MSR Asia single-author challenge

It has been 10 years since I posted up the single-author SIGGRAPH paper challenge to MSR Asia, and nobody has managed to claim the prize as far as I know.

Looking back at my writing, I was wondering who this blunt prick is.
If I could, I would tell my past self to be more graceful without compromising the strength.
Otherwise, I still stick with, and have faithfully followed by own edicts, after switching into these other roles.
