yakhu @gremble.xyz · 26/09/2026It should be obvious that I am working through my procastrination. I've made a diagram. The keys changed because the staggering was degrading performance more than I wanted. 000
yakhu @gremble.xyz · 26/09/2026In the spirit of Le Cunn's talk, I am adding MPC into my ablation study. "What if we entirely ablate the RL step and use a 2-step look-ahead MPC controller?" The neat part of that is that I get to do some more math. 000
yakhu @gremble.xyz · 25/09/2026I've built my little guy to touch the keys. It can tell time to do a beat. I implemented randomised euclidean rhythms and random notes in a fixed key. Now the player won't adapt to different conductors. Yay for getting to report a negative result :| 000
yakhu @gremble.xyz · 21/09/2026It is always fun to do computational experiments where the reward function suddenly collapses after you made a change you thought was good :D 100
yakhu @gremble.xyz · 20/09/2026Implementing numerical algorithms from a paper is quite difficult. I was pleased to get this working last night. Now I just need to figure out how to add another coupling equation to model the diffusion of the chemo-attractant over the graph. 100
yakhu @gremble.xyz · 16/09/2026I just want to know what is the minimum amount of information you need to share for two little guys to be able to work together. Now I need to do Lebesgue integration :( 010

yakhu @gremble.xyz · 12/09/2026It is so demeaning to have to admit that my research is in AI. I am doing marl research just because I want to figure out how to get the little guys to play games effectively. I just want to know how to make decisions when working together haha 000
yakhu @gremble.xyz · 10/09/2026I should not be allowed to make decisions. I am working on a project computation differential equations and I realised that I am making my group members do an entire additional honours project for this subject. I am teaching them methods to solve DEs on graphs. 000
yakhu @gremble.xyz · 09/09/2026If we put the amount of compute going into the pattern recognition machine through almost any other system, I am fairly sure that we would be able to develop spectacular results from that as well. 011

yakhu @gremble.xyz · 28/08/2026Just so we are all aware: I am getting paid to build bayesian belief models on fiber structures. It is exciting, but I am not telling them I am doing that. They think I am doing data engineering :) 010
yakhu @gremble.xyz · 27/08/2026It is really awkward when you built a really nice and neat collocation method and then you forget to add a term to cleanly handle a non-homogeneous equation. It only clicked how to account for it on the walk to my car, so now I just won't get those marks but at least I know how to solve the problem 000

yakhu @gremble.xyz · 21/08/2026Spent my evening learning about pseudo-spectral methods for solving ODEs and PDEs. I figured out vandermonde matrices, now I just need to figure out how to get all of this to work for abitrary order DEs before Wednesday :D 000
yakhu @gremble.xyz · 14/08/2026"Very smart people have already defended humanities scholarship for its difficulty as well as its sometimes intimidating specialization."

yakhu @gremble.xyz · 12/08/2026Today was a good research day. I discovered that the quantity I am looking for has a name: Exformation. I also learned about Blackwell's Informativeness Theorem and the formulations surrounding that. So now I think I have a better language to describe my problem. Neat :) 000

yakhu @gremble.xyz · 06/08/2026What do you mean I need to figure something out and not just know it intrinsically? Also, Information Theory is teaching my that my intuition is worth shit. 010

yakhu @gremble.xyz · 27/07/2026ODEs keep humbling me. The fact that I cannot solve an ODE at the drop of a hat is something that I should work on. At least the easy ones - I am willing to give myself a pass on the beefy non-linear ones. 010

Reposted by yakhuDr Heidy Khlaaf (هايدي خلاف) @heidykhlaaf.bsky.social · 22/07/2026The coverage on this OpenAI incident is abysmal. Use of the terms "rogue" and "loss of human control" lead to groupthink as people lack the critical skills to understand the difference between "autonomy" and faulty reward functions in AI on a task it was directed and given access to do. 217870
yakhu @gremble.xyz · 21/07/2026Today was simplifying approximations of the navier-stokes equation in curvilinear coordinate systems. Actually just boundary layer things using Prandtl's approximations, but wow - I am definitely still a bit rusty. 000
yakhu @gremble.xyz · 20/07/2026They tricked me. Mathematical modelling is just deriving and solving PDEs. I've been hoodwinked. 000
yakhu @gremble.xyz · 15/07/2026Studying full-time after almost 10 years has gone more successfully than I had hoped - with geometry of PDEs being a notable exception 😅. However, I got two distinctions (research and symmetry methods in differential equations) and two Bs for robotics and global optimisation. I can **still** do math 110
yakhu @gremble.xyz · 10/07/2026I think I just built a multi-tenant datalake. It uses ducklake and postgres to run the catalog. My query execution happens using isolated processes running ducklake in-memory databases. And I have full tenant data isolation. I expose a postgres-like dsn so psql can just connect to it. 120
