I signed this petition to improve diversity in conferences on computational topology - the significant impact of underrepresented minorities in this field should be accurately portrayed in its conferences https://t.co/fDIAtfpR04

More tools for bridging the gap between geometric/topological data analysis and the empirical sciences :)

[Manish Saggar @manishsaggar]

Excited to share NeuMapper, our new computational framework for neuroimaging data analysis based on the Mapper algorithm from topological data analysis. Led by @calebgeniesse & @samircwrites Just out in @netneurosci https://t.co/OJ1NaZKcXm

An annual tradition I always look forward to eagerly—reading these impressive stories behind solving some of the world’s most important problems

[Melinda French Gates @melindagates]

In our Annual Letter, @BillGates and I reflect on the hard work, heroism, and global cooperation that brought us closer to ending this pandemic, and why prioritizing equity must come next.

I hope you’ll read it. https://t.co/dGxiepq0Zm

@DrBiden has a long record of kindness, empathy, and public service, and she’s continuing that moving forward. @WSJopinion, on the other hand, is clearly going a different way...

[Samir Chowdhury @samircwrites]

Looks like a great opp!

[Lorin Crawford @lorin_crawford]

Apply! Apply! Apply! Happy to answer any questions you might have 🙌🏾

@cindyintheory life really is better today 🤯

So cool. Thanks for your work in making this!

[Ben Bartlett @bencbartlett]

more fun with Lorenz attractors... this time from the particle's point of view!

[Samir Chowdhury @samircwrites]

@danjlurie Interested!

Happening now at #OHBM2020Posters! "Exploring the landscape of brain dynamics using topological data analysis" https://t.co/PF5IJKeDf2

[Samir Chowdhury @samircwrites]

By automating the parameter selection procedure and providing new posthoc analysis tools for the Mapper algorithm (that does not average across subjects), we hope to move closer toward clinical translational applications. (5/n, n=5)

[Samir Chowdhury @samircwrites]

#OHBM2020 attendees: Come check out poster 1114 at #OHBM2020Posters for our take on how insights on behavior and neurobiology can be revealed using topological data analysis and optimal transport. Joint w/ @calebgeniesse @manishsaggar. Tweetstorm incoming (1/n)

[Manish Saggar @manishsaggar]

@OHBM [2/6] Next-gen mapper: improvements include: (1) introducing a new nonlinear Mapper framework, (2) automating parameter selection, and (3) showing how optimal transport can reveal novel insights about neurobiology and behavior. @calebgeniesse @samircwrites

[Samir Chowdhury @samircwrites]

These constructions are derived from a new, nonlinear implementation of Mapper that stays in the high-dimensional ROI/voxel space... and its parameters are optimized via an automated procedure that relies only on the autocorrelation structure of the time series data

[Samir Chowdhury @samircwrites]

@geometricdog sure! beyond the references provided in that paper, an excellent reference is the Computational OT book: https://t.co/zIdM04gJIz
Tom Needham and I also released a followup work (with more code!) recently: https://t.co/3spugK16fc

[Samir Chowdhury @samircwrites]

For #CVPR2020 attendees: #diffcvml workshop happening now: https://t.co/ADsdjwiVPL

Exciting list of keynote speakers + short orals + flash poster presentations. Lots of TDA talks! Full program here as well: https://t.co/nU5LM55Xx2

[Samir Chowdhury @samircwrites]

Postdoc opening in the current market with exciting multi-lab collab opps🤯🤯🧬📈 combining math training with empirical science context has been instrumental in helping me clarify the societal implications of my research q. Apply if you think this could be a good fit!

[Samir Chowdhury @samircwrites]

Have been looking forward to this workshop for some time - glad to see the official announcement! Open to public w/ free registration

[MBI @mbi_osu]

Register now for the next MBI and TGDA@OSU virtual workshop on July 27-31! Optimal Transport, Topological Data Analysis and Applications to Shape and Machine Learning. https://t.co/xE3OdlU5Xg

If there are infinitely many parallel timelines, there are exactly (measure) zero where I will miss the nightmare of removing comments line-by-line before arxiv upload
