We show that (the spectra alone allows good discrimination of the samples based on rheology, (3D-PCA allows comprehensive and informative visualization of the data, and (that the rheological parameters are predicted accurately using a regression method such as PLSR; instead of using chemical ...

Goal: PCA aims to find a new set of orthogonal variables that capture the maximum amount of variance in the data, while SVD aims to find a decomposition of a matrix into singular values and associated singular vectors. Use of the Data: PCA is an unsupervised learning technique that can be ...
PCA is a dimensionality reduction framework in machine learning. According to Wikipedia, PCA (or Principal Component Analysis) is a “statistical procedure that uses orthogonal transformation to convert a set of observations of possibly correlated variables…into a set of values of linearly uncorrelated ...
potential in SCG to reduce the reliance on curated labels50and propose adding self-supervised pre-trained model embeddings to biological analyses alongside principal component analysis (PCA), a practice exemplified by platforms such as CELLxGENE44. However, our benchmarking of SSL methods revealed the...

Phase recovery (PR) refers to calculating the phase of the light field from its intensity measurements. As exemplified from quantitative phase imaging and coherent diffraction imaging to adaptive optics, PR is essential for reconstructing the refractive
