    Here's Lecture 4 of CAT, containing chain homotopy, exact sequences, and in particular (my personal favorite) Mayer-Vietoris. There are two sins of omission [Def 3 and Def 9, can you find them?]. These will be fixed over the weekend. Enjoy!

    At every single step of my career I have felt the critical gaze of people not quite believing I can do my job, of taking extra time to trust me, and not being sure if that’s because I’m a woman, or brown, or both. That’s how discrimination feels. Subtle, constant, undermining.

    reference request: are there nontrivial examples of problems in variational inference where one can provably solve the KL minimisation problem? i.e. find global minimiser in polynomial time. the only one i'm currently aware of is fitting a Gaussian to something log-concave.

    Lecture 3 of computational algebraic topology is up! Here we meet Euler characteristics, chain complexes and homology. If you make it to the end, there's ONE WEIRD PICTURE THAT EXPLAINS EVERYTHING. OTHER IMAGES HATE IT.

    Stuck in train and barely breath as it is fully packed ! And why on earth am I thinking about higher (>2) dimensional homology groups!!

    Twitter Topology: Do we know what 3-dimensional homology captures? Is there even a name for it? Am I even asking the right question ?

    In 2013, Yitang Zhang gave a stunning proof on Bounded Gaps Between Primes. He's not a conventional academic by any standard. The dichotomy b/w being *free spirited* and the constraints of *tenure-track* (from his doctoral advisor) is interesting.

    Just now at Delancey and Norfolk in the Lower East Side an accident ran over a pedestrian trapping them under an SUV. Onlookers just lifted the SUV, dragging the victim out.

    Followed the conversation on EU's moratium proposal? calls for tech sector to pause sale of facial recognition to police, retail, schools, airports until technical, legal & ethical questions are addressed.

    For all the brave souls following along on twitter, Lecture 2 is now online :) Here you will meet homotopy, carriers and nerves. If you *really* want to learn things, meditate on the homework: Good luck!

    Finally!

    Discussion continues following the leak of a draft white paper claiming to reveal that the EU Commission is considering a ban of technology. We look forward to consulting with parties involved ahead of its final release.

    this company is scraping your entire visual web presence — photos on Facebook, YouTube, Venmo, etc. — and handing those images over to the police in the form of a giant facial recognition database... tech companies cashing in on the surveillance economy
