Independent Component Analysis

Can I use IPCA on gene microarray data? And is IPCA for clustering or classification analysis?
Thank you


Hi Asmawi,

In our paper, we have primarily applied IPCA on gene expression data, but other users have used it for different types of data. We developed IPCA to address some of the limitations of PCA (which assumes that variance explains the information in the data). There is also a sparse version available to select the top variables.

IPCA is similar to PCA, it is an unsupervised method, best for data exploration. For a supervised analysis, we recommend you use PLSDA (see several examples in our vignette and website
