I graduated last September and received the Dean’s award today (2022/03/24). I have been fortunate to meet with so many wonderful people here in UTokyo. I wish them the best for their future. I would not have been able to receive this award without their support.

After graduation, I have joined Preferred Networks in October 2021 as a researcher to work on applications in healthcare and quantum chemistry domains. I will still be in Tokyo for a while :)

🖼 A picture is worth a thousand words - especially when the words used to describe it are wrong. In this #MadeWithTFJS episode, @helloksong shows how adversarial.js can break any neural network in browser to change a 🐕 into a 🌭 and more. 📺 → goo.gle/3sgpGJY

The pre-print of our #emnlp2020 paper is now on ArXiv. arxiv.org/pdf/2010.04987.pdf So, I would like to use this thread to explain what we did. Basically, we proposed FIND -- a framework which enables humans to debug deep text classifiers. FIND = Feature Investigation aNd Disabling

Our work on human-in-the-loop debugging deep text classifiers (joint work with my amazing supervisors @fra_toni and @lspecia) has been accepted to appear at #emnlp2020 !! Here, we made interpretability more actionable for debugging. Stay tuned for the details. 🎉

Our work "Learning from Aggregate Observations" has been accepted to #NeurIPS 2020! We study a general *weakly-supervised learning* problem where supervision signals are given to *sets* of instances, while the goal is still to predict labels of unseen individuals.

This work explores how causal models can be fully exploited for domain adaptation! Intuition: humans care about causality (partially) because causal knowledge, once discovered, applies to different systems. ---- Joint work w/ Prof. Sato and Prof. Sugiyama. Comments appreciated!

Totally agree! Definitely one of the best talks at #NeurIPS2019. Very well-prepared and impressive.

If there is a talk you should watch from NeurIPS, it is the @EmtiyazKhan talk on Deep Learning with Bayesian principles (slideslive.com/38921489/deep…). @EmtiyazKhan and his co-authors build a beautiful bridge from Bayesian world to Deep Learning and high-order methods.

Deep learning and Bayesian learning are considered two entirely different fields often used in complementary settings. It is clear that combining ideas from the two fields would be beneficial, but how
