What people are saying
In the discussions, several participants refer to the publication's methods, such as generalized PCA and the implications of multinomial modeling on UMI counts, with comments like, 'the multinomial model adequately describes negative control data, and there is no need to model zero inflation.' The tone is predominantly technical, with many users expressing excitement and confidence in the proposed methods, contributing to an overall perception of high interest and potential impact.
Many discussions reflect a general support for the methods proposed in the publication, though there are some questions raised about specific aspects.
The discussions indicate a high level of curiosity about the application of the multinomial model in single-cell RNA sequencing, suggesting that the publication is relevant to current research interests.
While some posts delve into the technical details of the methods, others appear more superficial, indicating moderate engagement overall.
There is a strong belief that the advancements discussed in the publication can significantly influence the field of scRNA-Seq.
Abstract in brief
- The study focuses on improving feature selection and dimension reduction techniques for single-cell RNA sequencing (scRNASeq) data by using a multinomial model.
- Recent improvements in scRNASeq, particularly the use of unique molecular identifiers (UMIs), reveal that UMI counts conform to multinomial sampling without zero inflation.
- The authors propose innovative methods, such as generalized principal component analysis (GLMPCA) and deviance-based feature selection, which lead to better clustering performance compared to current normalization practices that can introduce misleading variability.

In https://t.co/7eElyZn5VE @sandakano introduced glmpca for scRNA-Seq: using a generalized version of PCA and PCA on GLM residuals as a fast approximation. In this nice paper @hippopedoid et al. now show that an improved version of scTransform is equivalent to the approximation. https://t.co/bEPX3xkTRF
But, as @GorinGennady regularly points out, there are some questions to ask. One of them is whether PCA throws out biological noise? That's for another thread. Here I'll just talk about normalization, as discussed at length in https://t.co/BT3wF5L0Ko by @will_townes et al. 6/

@lpachter And what do you think about generalized PCA as a dimensionality reduction method for single cell RNA-seq data? That seems quite principled to me... Also to project SNP data (using binomial error structure then)... https://t.co/ApEUKg5GN9 https://t.co/uLek7JXRVC
@anshulkundaje @mbeisen @NimwegenLab For single cell RNA-seq data - is generalized PCA not potentially better / more principled? Maybe they should use that for SNP data as well in fact (with binomial error structure then)... https://t.co/ApEUKg5GN9 https://t.co/uLek7JXRVC

@NimwegenLab @ShahLabUCLA @jisaacmurray @MadS100tist Interesting point! So, if I understand well, your hypothesis here is that the real distribution of mRNA counts is log-normal, but the observed distribution is not. Evidence suggests that capture in scRNA-seq experiments corresponds to binomial sampling https://t.co/rn9L0j3ALb
@MadS100tist @slavov_n @arjunrajlab Also, as far as we know the sampling noise in scRNA-seq is binomial https://t.co/hqViG35JIp https://t.co/45i1vpIv4k. There is no way that that kind of sampling could generate power-law like densities from non-power-law distributions. And we show that by looking at control data

Townes et al., 2019 wrote a nice paper showing this. They show " PCA on log-normalized UMI counts can lead to distorted low-dimensional factors and false discoveries." and recommend glmPCA of raw counts, aka PCA of the deviance or Pearson Residuals https://t.co/w1WfzNHCbY
@hippopedoid @rafalab @JanLause We did some basic comparisons and didn't see a strong distinction (Fig S9,S10: https://t.co/tCdltE0FwX ). Aesthetically I prefer deviance resid bc they are more symmetrical, but Pearson has the compute advantage. I appreciate the more thorough evaluations you all have been doing!

In https://t.co/7eElyZn5VE @sandakano introduced glmpca for scRNA-Seq: using a generalized version of PCA and PCA on GLM residuals as a fast approximation. In this nice paper @hippopedoid et al. now show that an improved version of scTransform is equivalent to the approximation. https://t.co/bEPX3xkTRF
Moreover, this analytic solution is equivalent to the rank-one GLM-PCA developed in Townes et al. 2019 (https://t.co/aGCMkN1RZ9) by @sandakano @stephaniehicks @rafalab. This nicely unifies these two papers that were published back-to-back in @GenomeBiology a year ago. /5
