Image histograms, kernel non-parametric smoothing, & mean-shift are closely related. Here's how Pick a reference pixel (center of a patch) & a set of other "helper" pixels (can be non-local) we can make an image-adaptive convolutional filter using histogram of pixel values 1/9

👇This article by Lina Sorg does a fantastic job summarizing the talk given by my PhD student Jacob Roarty at #SIAMCSE25. He presented some of our work in the article "A deep neural network for a hemiarray EIT system." aimsciences.org/article/doi/10… ASU Mathematics SIAM

Vivi! Ingrid Lewis :-)

The submission deadline has been extended to March 31. If you would like to submit an article, let me know!

I am honored to be recognized by SIAM for my volunteer work. I’m always happy to give back to my math community and support the amazing work in applied mathematics! SIAM siam.org/publications/s…

Our article with Gabriela Jeronimo has now been published. epubs.siam.org/doi/full/10.11…

The 2025 Rocky Mountain Mathematics Consortium Summer School will bring together leading experts in analysis, partial differential equations, and their applications. math.asu.edu/rmmcss2025

📣 Call for Papers! Submit to our special collection in La Matematica honoring Ingrid Daubechies’ 70th 🎉 Topic: Harmonic analysis & applications 🗓 Deadline: Aug 1, 2025 link.springer.com/collections/ie… #Math #Wavelets #HarmonicAnalysis #CallForPapers #LaMatematica

Can you support my request to get a GSVD in scipy? Go to github.com/scipy/scipy/is… and say how nice it would be!

Thank you, SIAM! It is a pleasure to volunteer alongside so many inspiring colleagues, to support the math community through #SIAMCSE25 and beyond!

Excited to welcome Sven Leyffer to ASU Mathematics this Friday! He will meet with students and faculty and deliver our colloquium talk. Details here: math.asu.edu/node/9322

I am excited to be mentoring Govanni Granados through this program. I am looking forward to welcoming him to ASU Mathematics in a few weeks. Thanks to SIAM for making this possible!

Congrats to my students Victoria Uribe, Brian Sweeney, and Robby Pawloski. I am so proud of them! #ASUGraduates

The deadline to apply for GoGetMath has been EXTENDED to May 30th, 2025. Learn more about this excellent opportunity here: icerm.brown.edu/program/gogetm…

Esta escuela de Primavera en Deep Learning se ve buenisima!!!! vhttps://primavera-dl.github.io/

I wrote a short post on some etiquette for a seemingly mundane task: declining an offer (for a job, internship, grad school, etc). Link in next tweet. 1/2

I’m excited to share that our latest article, “Efficient decomposition-based algorithms for l1-regularized inverse problems with column-orthogonal and Kronecker product matrices,” has been published in Inverse Problems. iopscience.iop.org/article/10.108…

On my way to Rio de Janeiro for the Applied Inverse Problems Conference. It should be great! Giving two talks this week on Iterative Methods for Computed Tomography and Variable Projection Methods for Regularized Inverse Problems #AIP25Rio #AppliedMath

The ASU School of Math and Stats invites applications for postdoctoral positions. The application deadline is November 13, 2025. If you’re interested, please reach out. apply.interfolio.com/175104
