Bean-counting

This has been a widely discussed topic, but when it comes to academic publishing, focus on quality over quantity.

Take my PhD adviser as an example. At this moment, he has “only” 27 journal papers and 40 conference papers according to dblp, but nearly 40000 citations, including 10+ papers with 1000+ citations, according to Google scholar.
In comparison, there are people around his seniority and in our fields (for calibration) with roughly 10-times publications but only one-tenth of citations.
(Citation is one of the mostly commonly used measure for quality/impact, but others are possible, such as products.)

He once told me that the best timing to publish papers is when people beg us to do so (using Brain Curless’ first SIGGRAPH paper as an example). That is probably too extreme, but publishing low quality papers not only wastes our time (it is better to go out and play) but also dilutes our reputation.

Sometimes the answers are hard to find because we ask the wrong questions.

Waking up in the middle of the night, sometimes I can remember ideas from my dreams.

Co-managing research materials

Filed under: Real — liyiwei @ 5:14 pm

Instead of hosting research materials on our own servers (as I did in the old days for both ongoing projects and published outcomes), it is more flexible to share on GitHub/Bitbucket public/private repos that need revision control, and store the compiled files in other services, such as papers on research gate or semantic scholar, videos via YouTube/Vimeo, etc.

With this setup, the co-authors can edit the research together, and I have less to worry about server management.

Revision control based on lines vs operations

Filed under: Real — liyiwei @ 10:52 am

I cannot believe I have not (really) noticed this earlier, but the current git/svn revision controls are based on simple line differences, without taking into account the actual editing operations which we actually did in SIGGRAPH 2011 for image editing.

As a very simple example, say a file contains an original line like this:

I love you. Do you love me?

User 1 breaks the line into two:

I love you.
Do you love me?

User 2 adds one word the line:

I love you. Do you love me too?

A revision control tool that considers editing operations can automatically merge the two edits:

I love you.
Do you love me too?

While the current svn/git tools, based on line differences, will simply give up and ask users for manual intervention.

Publishing two papers out of one submission

Filed under: Real — liyiwei @ 12:09 pm

Co-authors and I submitted a paper with two main parts to X, a top venue in our field.
The reviews said the first part is good contribution but the second part is basically nothing, and rejected our paper.

We then revised the paper and submitted to Y, another top venue in our field.
The reviews said the exact opposite from X, but accepted our paper conditional upon the removal the first part.

So we split the paper, with the second part to Y and the first part to (the next round of) X.

HPRT and CVML

Looking at the paper titles for HPG 2017, I wonder if it can be renamed to HPRT (similar to how CVPR can be renamed to CVML).

When we have real-time ray tracing on mobile devices (the day will come), all the legacy graphics algorithms (i.e. tricks) will become obsolete.
I believe real-time RT, instead of machine learning, will be the end of traditional rendering tricks.

Open source texture synthesis

Well I guess this is long overdue; knock yourself out here.
🙂

Open source facilitates collaboration and code reuse, and propels our progress forward. I shall participate more in the future.

And then the murders began

Technical paper authors could also get into the propulsive, forward-moving action, and to provide any necessary backstory more actively.
The outcome may be more fun and less dry for readers.

Paper length

Filed under: Real — liyiwei @ 11:08 am

The obsession with paper length is a legacy of printed proceedings.

What matters most is readability.
I would rather spend 1 hour reading a 20-page paper than 2 hours reading a 10-page paper.

Then follows file size: the smaller the better for storage and transmission.
