Pleased to share the updated version of our preprint, with @Mattowers1, @b_d_evans, @AlexGFletcher. https://t.co/3F8B7sByof. We showed that our strategy allows for accurate, understandable classification of another limited (but biologically unrelated) microscopy dataset. (1/4)

[The Alan Turing Institute @turinginst]

The Turing are delighted to be a part of this exciting new project advancing AI innovation for space safety & sustainability with @UniStrathclyde and @spacegovuk laying the foundations for an international virtual institute🚀#AI #SpaceSustainability #AISpaceTech

[James Briscoe @briscoejames]

I was delighted Marysia Placzek was awarded this year's @_BSDB_ Waddington Medal. Few are more deserving

Read about her contributions "Her papers are masterworks in precise observation and elegant experimental design, and many have become foundational"

Happy to share our latest work published in @BiologyOpen!

Here we formalize an unsupervised method, we call #insideOutside, for classifying interior and exterior points of the #blastocyst.

@mayfer Is this cheating? 😅

🚨 2 math bio PhD projects available with me @shefmathbio @mathsatshefuni both close collaborations with experimental biologists! 1) Understanding tissue patterning in a fluctuating environment https://t.co/aQvZtpcWto

[Alex Fletcher @AlexGFletcher]

Congratulations to @emanalwani on passing her PhD viva subject to minor corrections! Eman worked on models of patterning and polarity. Thanks to examiners @BlindMath and @NickMonk14 for taking time out from a busy semester, and from relaxing in a hammock somewhere, respectively.

Surprisingly, when we unpick the decision making of our limb classifier, we find that limb morphology is a substantially stronger classifying feature than SHH expression. (4/4)

[Ian Groves @IanBGroves]

Our classifier could discern between control and treated limbs, irrespective of developmental stage, at up to 94.4% accuracy. (3/4)

New paper:
"The Effects of Regularization and Data Augmentation are Class Dependent"
by Randall Balestriero, Leon Bottou, Yann LeCun

TL;DR: Turns out some types of data augmentation helps some categories and hurt others...

V happy to see @Alexthemessiah, @KChinnaiya et al published. @SethBlackshaw @DRN_Sheffield @RadcliffeBlade Thanks All

[Ian Groves @IanBGroves]

@Katiegracee24 Thanks! And for coming to talk about it, I'll make sure to check yours out as well

[Ian Groves @IanBGroves]

I'm presenting a poster (P257) at #BSCBDB22 on my work using deep learning to classify subtle morphology changes in the chick embryo. If you're interested, please come see and chat!

🚨Two days left to apply for two 3-year postdoc positions in math bio with me @mathsatshefuni @shefmathbio : visit https://t.co/FrY7luQWKX and search for UOS031828/UOS031829 for more details!🚨

[Ian Groves @IanBGroves]

@StanStrawbridge Thanks Stan!

[Ian Groves @IanBGroves]

Finally, saliency mapping provided the surprising insight that one of our sub-stages was best described with features that we didn't use to label the data, which will help inform future experiments.

[Ian Groves @IanBGroves]

I'm excited to share the preprint of our paper! (AFAIK the only authors on Twitter are @b_d_evans, @AlexGFletcher). https://t.co/MeVHVsaxWX
Here we systematically examine how to use domain expertise to expand a small microscopy dataset for DCNN classifier training.

[Ian Groves @IanBGroves]

We found that we could achieve high classification accuracies (relative to the size of our dataset) of up to 90.9% by fully exploiting these data processing regimes.
