Excited to share our new @NatureComms paper introducing #meta #visualization!

We show how to optimally combine any set of #data viz (e.g. #UMAP #tSNE #PCA) into 1 visualization to better capture true data structure.

We have an exciting #computational paper out in @CellRepMethods@twitter.com. Ever use a #tSNE or #UMAP in #scSeq, #flowcytometry or #masscytometry? It doesn't have to be just a pretty picture anymore - we've developed a statistical test to check for differences. 1/6

The maths is the brain-child of Carlos Roca - I certainly didn't expect to publish a paper with these equations! Basically, Cross Entropy looks at the relative position of each each to all other cells, allowing you to test for differences in the "shape" of the #tSNE or #UMAP. 5/6

Somebody wrote here that "𝘮𝘶𝘴𝘪𝘤 𝘪𝘴 𝘫𝘶𝘴𝘵 #𝘮𝘢𝘵𝘩𝘦𝘮𝘢𝘵𝘪𝘤𝘴, 𝘣𝘶𝘵 𝘭𝘰𝘶𝘥𝘦𝘳". #Math is indeed beautiful.

Analyzing high-dimensional data (10^6 samples, 100+ features) in #Python, using #Sklearn Looking at that data thru a manifold, reducing the number of dimensions to 2 (e.g. a sheet of paper), sometimes to 3 (#3D model), with the help of #TSNE method.

It doesn't cease to amaze how many living creatures, leaves, insects I see in this unreal world😍

The super cool thing is that once you've segmented them, you can start to cluster them based on simply properties like area, circularity and solidity.

You can automatically classify into resting (red) and activated (green) microglia! How cool is that?

Nothing like the #Kaggle #fashion #MNIST variant to make me feel like a real Elle Woods over here doing t-SNE on purses and saliency maps on ankle boots 😅
