@cup_of_what GG bientôt les 300 ! Avant début décembre on espère 🙏

@grantyboy_ @engineers_feed You can make it even more complex by using determinants ! :)

I'm thrilled to announce that the *Dall-E Mini* @gradio app is now live on @huggingface spaces 🪄🔥

We've been working with the fantastic Dall-E Mini team (@borisdayma et al.) who built the model to generate images from any sentence

TextStyleBrush is the first self-supervised AI model that replaces text in existing images of both scenes & handwriting — in one shot — using just a single word. Read more: https://t.co/0QfLraAQvV

The Modern Mathematics of Deep Learning

A review paper (textbook) on the mathematical analysis of deep learning, with an emphasis on the generalization power of overparametrized neural nets and the role of depth in architectures.

Pour ceux qui ne lisent pas le russe 😉, l’ISS va encore grandir avec l’arrivée d’un nouveau module destine à la recherche scientifique – hâte d’aider à son installation ! 🇷🇺🔬

After 4 hours of searching for the best params and solving bugs in my optimization, I managed to get this almost perfect run using the data of a DonkeyCar (max angle, speed) and the real distances of the map !
Time for 1st lap : 16.65 s
Estimated time for 2nd lap : 16.8 s

[AIDRI_ @AIDRI_]

Yesterday, I beat my best time in a #matlab simulation : I went from 16.65 sec to 15.66 sec on the "Generated Track" of #Donkeycar. Let's implement the controller to be able to test all of this in the Donkey Sim (in progress) !

[AIDRI_ @AIDRI_]

@a1k0n @DWalmroth @diyrobocars I tried the TUMFTM project which uses ipopt. It is true that the solver works well and does a superb optimization (on the default map). I should try to implement it in my project !

[AIDRI_ @AIDRI_]

I finally succeeded in optimizing the trajectory and speed of a car on a #racetrack.
Next step: implement a 2d controller and test it on a #donkeycar simulator !
(The map is "Generated Track" from DonkeyCar Sim)

@Moodisme Yep,
To optimize the path :

To control a car, there is a great mooc on coursera : Intro to Self Driving Car. The first part will teach you how to make a 2d controller to drive a car !

@a1k0n @DWalmroth @diyrobocars I never heard about ipopt. Actually, I use quadprog which is not very famous for non linear opti, but it makes a good work. There is an implementation on github of an MPC in Matlab using quadprog if you want. I use it to compare my result with a good implementation of the paper.

@DWalmroth @diyrobocars I used an algorithm that is based on a GPA. If you want you have a great research paper that helped me a lot: https://t.co/CpMefuqUcb

[AIDRI_ @AIDRI_]

@rf_engine Yes, it could be interesting. I'll try to find a file with the waypoints taken by a F1 driver, and I'll run my algo on a F1 track, the comparison should be interesting? After, would a F1 team want to have an algo in its team... 🤔

Lap time :
1/ 2.72 sec
2/ 2.56 sec
3/ 2.56 sec

The map is a 1:1720 representation of the real map.

@korymath what the font will probably not give good results since the DeepFont algo has been trained on AdobeVFR (≈2500 fonts), but this dataset lacks examples of uncommon fonts, and some images were hand-annotated, which can makes it inaccurate.
To me, this font looks like "Munter"...
