Fairness

Filed under: Real — liyiwei @ 4:03 pm
Tags: ,

Tedros Adhanom Ghebreyesus said it was not fair for younger, healthy people in richer nations to get the jab before vulnerable people in poorer states.

If we continue this line of reasoning, is it fair for younger, healthy people in richer nations to receive more heath care, social welfare, etc., than vulnerable people in poorer states?
How should we define fairness across different groups of people?
Is such fairness achievable or desirable?

Genetic donation

A discussion about sperm donation came into my mind a few days ago.

All biological beings are built to spread and continue their genetic legacies. However, I should also be responsible on how my genetic future will match, grow, and further spread. And thus consider one-way blind donation unsuitable for me.

Stolen package

I noticed a missed delivery slip near my front door. As before, I filled it out for redelivery without requiring signature, but the package never came and the staff could not find it in their office. Due to its content, I guess the package has been stolen. I did not keep a copy of the delivery slip since the process has worked before a few times.
Lesson learned: keep the due diligence and never let my guard down.

Common law versus civil law

Filed under: Real — liyiwei @ 12:12 pm

Quote from here:

The main difference between the two systems is that in common law countries, case law – in the form of published judicial opinions – is of primary importance, whereas in civil law systems, codified statutes predominate.
But these divisions are not as clear-cut as they might seem. In fact, many countries use a mix of features from common and civil law systems. Understanding the differences between these systems first requires an understanding of their historical underpinnings.

So, common law is data-driven while civil law is procedural.

How to deal with randomness in life

Filed under: Real — liyiwei @ 3:31 pm
Tags:

[This is my reply to a co-author who expressed concerns about the randomness in peer reviews.]

During my military training, a saying went like 散彈打鳥不死也傷, which roughly translates to “if one shoots enough bullets into a forest eventually a bird will be hit”.

(There are others related quotes such as “the best way to have a great idea is to have a lot of ideas” by Linus Pauling, but shooting bullets feels more concrete/visceral.)

Other things being equal, more attempts tend to reduce statistical variance and increase the numbers of success.

Rick retiring

Filed under: Real — liyiwei @ 12:49 pm
Tags:

I received an announcement earlier today that a prominent member of our research community is scheduled to retire next month, which made me think about what it means for a research scientist to retire.

To me, it means all the extra time and freedom to do whatever I want, such as single-author a SIGGRAPH paper in an exotic topic that I wouldn’t be able to find support from funding agencies or company managements. (I used to joke with my students that I plan to single-author papers when I am 88 years old.) But I have yet to reach that biological and career stage, so I cannot predict what I can or want to do then.

Maybe I will write a follow-up post when I turn 88.

Epistemic dependence

Filed under: Real — liyiwei @ 11:16 am
Tags: ,

I found this article a nice read, which highlights the much faster growth of our collective knowledge (accelerated by computers and algorithms) than our individual brain capacities (constrained by biology and evolution). Each one of us knows a shrinking slice of the world, and this has profound implications on our society and civilization.

One, as mentioned in the article, is the increasing need of collaboration among researchers, especially for experimental science. (At this moment of writing, it is still feasible to single author a computer science paper.)
Even though the numbers of co-authors of my papers have not increased too much, I do find it increasingly harder to know exactly what is going on in every aspect of a project, notably detailed implementations and user studies.

Another timely topic is about politics.
The policies can become so complex that nobody really understands what is going on.
Thus, each voter knows only a tiny aspect of each political topic or candidate, and thus can form drastically different opinions from one another. This can be a scientific factor driving political polarization, even without other factors like social media. Fortunately, Monte Carlo sampling indicates that with enough (sufficiently independent) samples, the aggregate estimation can still be robust (low bias/variance).
For example, the US essentially has 100+ million votes for the presidency, which should give us confidence on the outcome, no matter how ridiculous it may look.

Research goal post

Filed under: Real — liyiwei @ 10:09 am
Tags: ,

In my personal experience, there are two ways to guide a research project: solving a specific problem with whatever solutions that work the best (based on a variety of criteria such as quality, speed, cost, etc.), and devising a novel idea that can span different problems, domains, and applications.

The problem-oriented approach happens more in engineering (which aims to solve practical problems) while the idea-oriented approach happens more in science (especially more theoretical fields like math which aim to formulate fundamental ideas behind a plethora of phenomena).
Solving a specific problem provides a clear goal and reduces the tendency to derail, while aiming for ideas is more likely to work after one has already worked on related problems so as to condense the experiences into the core forms.

What can be quantified can also be automated

Filed under: Real — liyiwei @ 10:00 am
Tags: ,

If the productivity of certain types of works can be quantified, it can also be optimized and thus automated.

Instead of performance evaluation, such measures are better used for identifying repetitive tasks potential for automation.

To achieve human-level intelligence, we probably need an AI framework very different from existing rule-based (e.g., Minsky) and data-driven (e.g., current ML) approaches.

OKR 2020

Filed under: Real — liyiwei @ 10:08 am
Tags:

For OKR 2019, I rated myself 80 percent:

  • Published 4 top papers with 4 student first authors.
  • Transferred a research into a product for future release, and have 1 granted and 2 filed patents.
  • Maintain regular drawing and animation exercises with steady progress.
  • I read the Book of Change as part of my drawing exercises, and have resumed the Baroque Cycles.

    By avoiding a brand of low-quality chocolate, I have restored my biometrics to the previous non-normal-human level.
    I have learned all 3 basic forms of the physical art I have started learning for about 4 years ago.

The default period is from July 2020 to June 2021 unless stated otherwise.

Publish top papers

Publish at least 4 papers in top graphics/HCI/vision/ML venues, such as ToG (including SIGGRAPH and SIGGRAPH Asia), CHI/UIST, NIPS/ICML, CVPR/ICCV.

Build top products

Ship at least one product as a manager/researcher and file at least two patents.

Develop top talents

Help at least 4 students publish in top graphics/HCI/vision/ML venues individually.
Recruit at least 2 top job candidates.

Lead top impacts

This year marked so many remarkable events, such as a global pandemic, environment degradation, and social injustice, which are more worthwhile to address than the above 3 categories, which I no longer feel the kind of urge to prove after SIGGRAPH 2011.
I (belatedly) created this new category for the coming years.

Have fun, be awesome

Practice sketching and animation to a professional level.

Continue learning a Middle Eastern language to elementary school level, complementing the one Asian and one European language I already know.

Practice meditation to the level that I can enter the God mode immediately, anywhere and anytime.

Finish the book of change, to renew my (now rusty) Chinese and crack the only Chinese classics that my grandfather did not during his life time.

Finish the baroque cycle, which I have resumed in the middle of the first volume (quicksilver).

Recover from an acute physical incidence that threw me off balance, and fix a chronical one.

Sharing paper source with publisher

Filed under: Real — liyiwei @ 9:00 am
Tags: ,

Some publishers like ACM might ask for the source files to compile the camera ready papers. My understanding is that they need the source to tune the paper format, instead of publishing the source. Thus, it should be OK to share the source directly with the publisher.
If you have concerns about internal annotations such as author discussions not meant for the final paper, just clean up the source via arXiv Latex cleaner or something similar.

Meanwhile, one intern submitted a paper to a top venue even before the start of the internship, and is now spending time revising the conditionally accepted paper, filing a patent, and collaborating with a product team, instead of campaigning for popularity among other interns.

Our time is very limited. As a research mentor, it is my responsibility to guide you towards what is important and steer you away from what is less so.

Morning energy

Bananas probably have one of the highest benefit-to-cost ratios among all food: nutritional, healthy, easy to consume, and low cost, despite their lack of genetic diversity and (like other fresh produce) perishable for storage and transportation.

It was great to (virtually) meet with my PhD adviser after all these years. I was trying to discuss collaboration and he told me that he just wanted to catch up.

I have been bumping into the same group of people throughout my career; maybe we are a small community.

Decomposition

The disintegration of a dead body is its reintegration back to the nature, and inspires me to decompose my sketching.

I walked up to the wait area, told the librarian my name, and received the book in a shopping bag.

Gift from the cat

The neighborhood black cat seemed to express his affinity by occasionally laying dead rats around the house.
I spotted this one in the backyard earlier this morning, but it disappeared when I tried to draw it in the evening; fortunately I have a reference photo taken earlier for backup.

Memory of a silverfish 衣魚

Filed under: Real — liyiwei @ 8:55 pm
Tags: ,

I spotted a silverfish in the morning, which reminded me of those I constantly saw in my grandfather’s numerous ancient Chinese texts, which he refused to throw away any despite repeated demands from my grandmother. (Is this house for people or books to live in? 這房子是給人還是給書住的?)

He started to teach me classical Chinese when I was in kindergarten, and told me several important and unconventional lessons, such as: do not trust everything in the history books, better to beat others with my brain instead of my fists, and never let others control my thoughts and actions.

Lack of energy

I did not bring out the underlying energy in this exercise of sketching secondary dynamic effects, and thus most of them look lethargic.

I drew two circles by my left and right hands with onion skinning over multiple frames, and observed the circular animation caused by unsteady hand motions.

Lonely excavator claw

Filed under: Real — liyiwei @ 8:22 pm
Tags: ,

I saw this excavator claw sitting alone on the road side a few days ago, and walked back to sketch it.
The road is meandering and thus the car traffic can be a bit dangerous for pedestrians.
Fortunately, I can stand on the down-wind side of the claw, under the protection of its size and weight.

Road roller

Filed under: Real — liyiwei @ 9:08 pm
Tags: ,

I saw this road roller parked at the corner of a nearby fire station, which has a nice low wide stone wall for me to sit comfortably while sketching.
The connectors between the wheel/drum axes and the body seemed obstructive while on site, so I skipped them but found them pivotal for the structure and composition after the first drawing.
I came back to add the connectors the next evening.

Mamba graduation wine bottle

This is my first graphic design, to celebrate the graduation of my last HKU PhD student who derived her nickname from the black mamba.
(I managed to help her publishing top papers but not converting her from LAL to GSW.)

I was trying to draw a temple building but lacked enough time before the evening closure, so I switched to another nearby scene.

How to choose faculty jobs for research universities

Filed under: Real — liyiwei @ 4:55 pm
Tags:

The first rule, which you will also hear from others, is to choose a place that can attract top graduate students whom you can work with, because that is the main attraction for being a professor in a research university.

After that, consider other factors, like funding and geography (and thus why I went to HKU as a professor).

草草了事 undeleted from a restless afternoon

Filed under: Real — liyiwei @ 9:31 pm

I was trying to sketch Dona Arguello‘s statue from a sliver of shaded area in a hot afternoon but could not gather enough interest within the allocated half hour, so I deleted the file, but restored it to continue from memory at home.

Pencil and pen sketch of an unlit corner after sunset

Filed under: Real — liyiwei @ 9:18 pm

I went out after 8 pm to this interesting and yet unlit corner of my neighborhood, to force myself to either draw quickly before it was too dark and/or finish the rest from visual memory back home.

When I picked up this pine cone it was still oozing sap, and has remained on my desk as an aroma source and hand exercise instrument.
