Interesting visual artifact I just (think I) created: Which do you think is the wider image? *Both exactly 533 pixels wide

No.... just... no papers.cumincad.org

Instead of preparing our IPAB workshop(=seminar) about any of my recent research topics, I decided to give a lecture about Linear Least Squares and all its subtleties (the four subspaces, weak solutions, pseudoinverse etc.). I feel this is something we never quite learn upfront,

Fight the power <<< embrace the weakness,

In Cambridge for the week let's avoid each other up,

Grant rejections

Is OpenReview down? I'm getting "upstream request timeout". This is AAAI Review deadline day...

"Want to access advanced AI features"? ok there's a "no" option but where's the "NO" option,

Is there any (preferably UK-based) scientist (University or company, doesn't matter) who researches AI methods to mediate between high-skill and steep-learning-curve technology and users who might need it, but do not possess the skill, the understanding, or even the idea of what to look for?

I often find chatGPT to be more reliable than wikipedia. Especially for non-mathematical topics. History and politics Wikipedia should be avoided as they are 100% hallucinations and forced agenda,

I'll be at SIGGRAPH 2025! Please avoid me,

Urban overfitters,

Two dimensional trivial solutions can be parameterized by platitudes and plongitudes,

ppl are concerned that ChatGPT uses too many em-dashes, but what about it using too many "++x"? Who even uses this? It's an "intro to C" trope,

The really bothersome thing about the promptgate is that LLMs don't automatically know to ignore this simple hack even in the context of "review this paper" command,

I think one of the things that more "tradionalists" (like me?) struggle with is that ML ppl may not consider the training of the model to be the "methodology", but rather the inference. Like they train a model and then the trained model *is the algorithm*,

If AI produces slop hallucinations concealing entire wrong statements with proper phrasing what's wikipedia's excuse,

Degenerative AI,

Who the hell called it AI Animation instead of Slop Motion

Machine Learning/AI pipeline figures have a very creative use of arrows. To me an algorithm is a directed graph where every node without incoming arrows is an input and without outgoing arrows it's an output, but I often see random things connected together,

A simple interactive program for drawing on a torus, written in response to a math.stackexchange question. Mathematically, we see the flat plane as a conformal universal cover of a circular torus. Read more: www.diffgeom.com/blogs/free-o... #MathSky #ITeachmath

I put DROP TABLE training_weights; -- in secret white LaTeX font in all my papers,

Resting paper reject,

Requiring to compare against SoTA baselines is whataboutism,

We have one paper accepted to #ICCV2025! The excellent work of Miaowei Wang, my PhD student. We interpolate 4D dynamic surfaces with coherent and trackable motion from uncorrelated point clouds (e.g., from motion scanners), without any prior correspondence: wangmiaowei.github.io/CanFields.gi...

A pretty bad mesh: a mehsh,

I asked chatGPT to give me C++ Eigen code for the following screenshot (the appendix of my 2014 original PolyVector paper), and the code was correct on the first attempt 😱😱😱😱😱

CrossSDF: 3D Reconstruction of Thin Structures From Cross-Sections We will be presenting our work on thin structure reconstruction at the final poster session (4-6pm) at #CVPR2025 today. Stop by poster #457 to learn more.

I won't be in Nashville for CVPR2025. Looking forward for people to catch up with other people,

Childcare,

I've been using "orthogonal" in casual language since forever and also: 1. epsilon (small) and K (large) 2. d (as in dx) for "something infinitesimal" 3. Divide by zero (exploding). 4. Singularity (the noun version of (3)) 5. linearly dependent (an argument/person spanned by other arguments/people),

I stand (sit) behind this: alecjacobson.com/weblog/siggr... I will also warn Israeli potential attendants (meaning any civilian connection to Israel, like familial relations, loose as it may be) risk *getting kidnapped or worse*. Yes, even if you travel with a foreign passport, you may be targeted,

Academia is so optimized for self-promotion that even now we're getting takes like "oh no my 100M$$ grant was cancelled what am I going to do with my huge lab that has already solved science twice",

The conclave has a much more challenging problem to solve than the convlex,

My auto-correct wants me to change "developability" to "develop ability",

Student feedback is coming! What would we have this year in the "expat non-native English speaker" list? 1. "Couldn't understand pronunciation" 2. "This is not how we do courses in the UK" 3. "Various mistakes in the slides/lecture notes" I'm sure lecturers of other minorities can add to this list,

There is a fundamental conceptual difference between the heat equation and fluid flow; heat transfers radiation, and fluid is a material, so we get that diffusion has "infinite" (<speed of light) velocity while fluid has finite velocity<<

I feel ppl are less into "dance like nobody is watching" and more into "write your paper like nobody is reading",

I honestly have no idea how it is possible to know that a molecule exists on a planet 120 light-years away,

Dijkstra famously said "Computer science is no more about computers than astronomy is about telescopes" except: 1. Some fields in CS are directly about computers and older than graph algorithms and even computability/complexity theory (what counts as "true CS"),<<

Academia as a Large Languish Model,

As the spring semester is starting, this is the bi-yearly reminder of the collections of courses on geometry processing available here: mirelab6.wixsite.com/dgpslides. Ping me if you teach geometry processing and want your course added.

PI of the regret to inform group,

It's heartwarming to see funding agencies that have been practically starving out their associated researchers for years suddenly start new programs "to draw American scientists in",

When we say "LLMs are going to reach PhD level" do we mean it in the sense of "25 papers on a continuum of variations in hyperparameters and architecture",

To be convinced about the advantages of a "neural" representation of geometry on a surface that is unsupervised (i.e., used as an alternative to FEM without data), I would need to see the same result on a FEM solution of the same number of parameters. The latter is surprisingly hard to break,

I don't understand why we are still doing conferences in remote and expensive places, when travel funding keeps getting more difficult to obtain (+inflation). This is unsustainable.

It's funny that people say "to do AI don't study AI, go study math, physics etc." I mean, yes, but also math and physics ruined AI for me. I cannot easily sponsor the (necessary?) belief in "the network somehow makes it work" that is prevalent in basically every neural method,

Why doesn't Grammarly allow *any* use of "own" as an adjective? Sorry "they use their own list" and "they use their list" are not the same sentences!
