To compute the movement of the state x(t), we need to temporally integrate its velocity field ẋ(t). 🤓 The control signal steering angle stays at 0, then 0.05π, then linearly to −0.20π. The vehicle moves along circumferences. Finally, a sweep of initial velocity is performed.

Currently, writing chapter 10, «Planning and control». Physical constrains for the evolution of the state (e.g. pure rotation of the wheels) are encoded through the velocity of the state ẋ = dx(t)/dt, a function of the state x(t) and the control u(t).
Releasing the Energy-Book 🔋 from its first appendix's chapter, where I explain how I create my figures. 🎨 Feel free to report errors via the issues' tracker, contribute to the exercises, and show me what you can draw, via the discussion section. 🥳 github.com/Atcold/Energ...
On a summer Friday night, the first chapter sees the light. 🥹🥹🥹
Yeah, it took me 20 days to get back 🥹🥹🥹 I swear I respond to instant messages as they get through! 🥲🥲🥲 Anyhow, one more successful semester completed. 🥳🥳🥳
In this lecture from my new undergrad course, we review linear multiclass classification, leverage backprop and gradient descent to learn a linearly separable feature vector for the input, and observe the training dynamics in a 2D embedding space. 🤓 youtu.be/saskQ-EjCLQ
Training of a 2 → 100 → 2 → 5 fully connected ReLU neural net via cross-entropy minimisation. • it starts outputting small embeddings • around epoch 300 learns an identity function • takes 1700 epochs more to unwind the data manifold

➡️ The lecture ML & DL Foundamentals II with Alfredo Canziani @alfcnz is now starting at #KHIPU2025 Remember you can watch it live at khipu.ai/live
In today's episode, we review the concepts of loss ℒ(𝘄, 𝒟), per-sample loss L(𝘄, x, y), binary cross-entropy cost ℍ(y, ỹ) = y softplus(−s) + (1−y) softplus(s), ỹ = σ(𝘄ᵀ𝗳(x)). Then, we minimised the loss by choosing convenient values for our weight vector 𝘄. @nyucourant.bsky.social
Tue morning: *prepares slides* Tue class: *improv blackboard lecture* Outcome: unexpectedly great lecture. Thu morning: *prep handwritten notes* Thu class: *executes blackboard lecture* Students: 🤩🤩🤩🤩🤩🤩🤩🤩🤩 @nyucourant.bsky.social @nyudatascience.bsky.social
I think the new undergrad course is going well. At least we're having fun! 😁😁😁

If you're interested in creative coding or simulations, come read The Nature of Code with us! I'm setting up a chill book club to read the book and share projects starting in January. DM me for info!
I was reading about Conway's Game of Life, and this whole amazing book is available online! The Nature of Code - by Daniel Shiffman Thank you @shiffman.net for making it free for the web! People, please consider buying a copy of the book :) natureofcode.com/cellular-aut...

It takes me weeks to detox from a stressful work mindset and finally sleep in — without waking at dawn, driven by the haste of unfinished tasks. I struggle to turn on my laptop to do any work. When I do restart, the anxiety comes back instantaneously. Is this common? ☹️☹️☹️

You’re still arguing about tabs vs. spaces? May I present…
Entropy is one of those formulas that many of us learn, swallow whole, and even use regularly without really understanding. (E.g., where does that “log” come from? Are there other possible formulas?) Yet there's an intuitive & almost inevitable way to arrive at this expression.

Me: what’s your poster about? Presenter (P): let me tell you about the theory of constrained optimisation of convex functions. Me: no, what was the goal? P: okay, so the framework of blah and blah has the KKT blah and blah blah blah conditions and… Me: high level, plz.
