About me
I am a Computational Mathematics student at Universitat Jaume I. Currently, my research focuses on inclusive speech recognition and the robustness of models against geometric transformations. I have experience in real-world ASR and computer vision projects, as well as publishing scientific papers.

Interesting Stuff (to me) 🧪
Tangling and Untangling Orbits in Latent Space
This example shows the result of continuously subjecting a natural image, I, to the SO(2) rotation group and analyzing how the orbit generated by the latent dimension of a neural network is organized.
It demonstrates how, as progressive levels of Data Augmentation are added to the neural network (making it more invariant), that orbit becomes untangled.
