We are excited to welcome Prof. Alejandro Rodriguez Garcia from the Abdus Salam International Centre for Theoretical Physics (ICTP) to Enabla! In his lecture, Alex continues the topic started by Marcello and explores the use of unsupervised machine learning techniques in many-body quantum systems, highlighting how dimensionality reduction can illuminate structure within complex data. Particular emphasis is placed on the Principal Component Analysis (PCA) as a key method to maximize variance while reducing dimensionality. This lecture sets the stage for future topics such as clustering and manifold learning.

🎥 Join us for this #OpenAccess lecture and take advantage of Enabla's unique features to ask questions directly to Prof. Rodriguez Garcia and engage in discussions with the community: https://enabla.com/pub/1112/about

Don't miss this opportunity to enhance your knowledge in the intersection of data mining and quantum physics!

Why the simplest explanation isn’t always the best: #DimensionalityReduction such as #PCA can see structures that do not exist and miss structures that exist. The simplest explanation isn’t always the best.

Ahh I've been so excited for this paper to come out for ages!! No affiliation, just think it's super cool:

"Collection Space Navigator" for exploring projections of visual art collections

Honestly, when I first saw this, it wasn't the art applications that intrigued me so much as the value it offers for understanding 'slices' through high-dimensional space.
