Confessions of a researchaholic

Sharing unpublished research work

Sharing a research work that is not yet published (not even a preprint on arXiv) can have several benefits, such as receiving early feedback, increasing visibility (especially for junior researchers), and attracting potential collaborators.

On the other hand it also has some risks, such as being scooped by others or jeopardizing anonymity during the review process or public disclosure for patent application.

To maximize the benefits and minimize the risks, I suggest sharing only with trusted colleagues who have the expertise to provide constructive feedback and ethics to maintain confidentiality. If the paper is still under review, check the conference/journal policies (e.g., this for SIGGRAPH). For patent application, any public disclosure will invalidate international filings but there is a one-year window for US filings.

SIGGRAPH production talks

While at SIGGRAPH conferences I usually spent the majority of my “attendance time” in the animation festivals and production talks primarily because (1) the contents are usually not recorded for later consumption, (2) the effects look nice, and (3) the topics tend to be something I am less familiar with, even after 20+ years in the field.

The animation creations and effects productions are hybrids of art and science/engineering.
Each effect is tailored for the specific style and story and created by a combination of artistic practices and off-the-shelf/bespoke tools.
The presentations tend to focus on the design process and tools deployment, instead of technical methods and implementations.

Unnoticed review assignments

Upon noticing a reminder email about upcoming reviews due for a conference 3 days ago, I realized that I haven’t received any prior notifications about the assignments and thus haven’t started reading the papers yet. It is not a good form to miss reviews, especially for a conference that I previously chaired, so I spent an intense long weekend reviewing these submissions.

Trend following II

Joining a hot research trend is like buying a stock when the price is high.

These neural network pioneers (like Hinton, LeCun, etc.) started their works not when the field was hot, but when it was considered a dead end. And they stuck with it for decades until the right circumstances (e.g., GPU compute finally became feasible). Now, every time a new idea (about generative X or whatever) pops in the head, there might already be 10 arXiv papers on it.

It is important to know any significant new advancements, but it is even more important to figure out what and how to apply these into our own research and be able to formulate our own (unique) vision.

Holiday time for exploratory fun

Monday the 17th is a holiday and I was pondering whether I should start a work task that I aimed to finish by the end of the week or spend time on more exploratory research. I decided to go for the latter as I realized that during my usual workdays I often feel enough obligation towards my collaborators for the former and I am the only one who can push myself for the latter.

My decision turned out to be correct for this particular one, as on Monday I had some fun tinkering with \href{https://glicol.org/}{computer music language} (that I have zero background with) and on Tuesday I immediately hit on issues that required responses from my colleagues upon starting the work task.

And I also spent some time doing some silly doodling:

Single-authored SIGGRAPH submission from a recent collaborator whom I have yet to meet in person

I just looked at a single-authored SIGGRAPH submission from a recent collaborator (with a first-authored SIGGRAPH paper before even getting into a graduate degree program), intentionally after the deadline to ensure that I wouldn’t be tempted to contribute anything to his solo effort (as I just did) before the review process.
I like the work and hope it will get accepted so that we could finally meet in person at the conference.
(Hopefully the Canadian visa would be easier to obtain than the US equivalence, as otherwise he would not have any co-author to present the paper.)

The devil sheds Prada

I used to concentrate my paper submissions to a venue that gained prestige by accepting only the most novel ideas, but its prestige has been diluted with more incremental works over the years to the point that it has higher acceptance rate than alternatives (in an overlapping but different field) that I now submit to more.

Art papers

I took a look at the art papers in SIGGRAPH Asia 2024 primarily due to the unusual preface and, to a lesser extent, the much lower (and thus more precious) number (28 only!) and acceptance rate (15.9%) than the technical papers program.

Unlike the technical papers which have clearer review criteria (novelty, importance, utility, readability, reproducibility, ethics, etc.), I agree with the art papers chair that it is not clear what is an art paper, not least a good one. I found some of the papers interesting in the technical or philosophical perspectives, while some others left me scratching my head. But I guess this is what art is in general – more about expressing/sharing novel viewpoints/experiences than scientific discoveries or practical utilities.

Most important skills for ML R&D

Secure compute resources and figure out the compatible combinations of Python package versions, and the rest will follow naturally. 😈
