📢 New on Medium: My Paper Was Outdated Before It Was Published Submitted. Waited. Rejected. Revised. Accepted. By then, 50+ citations and 1k GitHub stars. The field had moved on. Thoughts on fixing peer review in fast-moving fields: 🔗 rizbicki.medium.com/my-paper-was... #PeerReview

Big news—our paper was accepted for oral presentation at #UAI2025! 🥳 We (me + Vagner S. Santos, Thiago R Ramos, @rafael-izbicki.bsky.social ) built EPICSCORE, a method to improve conformal prediction intervals by adding epistemic uncertainty awareness. Here’s why it matters 🧵

É absurdo como muitos dos divulgadores científicos simplesmente pararam de cobrar vacinas quando o novo governo assumiu. Estamos faz meses tentando dar uma dose de vacina de covid para minha filha, mas está sempre em falta. Idem para idosos.

🌳 New paper! Led by Denis Valle, we present a nonparametric approach to quantify uncertainty in multistep upscaling models. We illustrate our methods for forest biomass predictions in the Brazilian Amazon. + #RemoteSensing #MachineLearning #ForestBiomass

I am happy to announce that a paper of mine, Rafael B. Stern and @rafael-izbicki.bsky.social has been accepted for publication at the International Journal of Approximate Reasoning 🎉 In our paper, we show how to build and test hypotheses of practical equivalence in nonparametric settings. 🧵

Decision regions based on a significance level alpha and a threshold epsilon for the gender wage gap data presented in the paper. For higher values of alpha and lower values of epsilon, the hypothesis is rejected. For lower values of alpha and higher values of epsilon, the hypothesis is not rejected.

Stop oversampling! Changing the cutoff in probabilistic classifiers is enough for imbalanced data. In our new paper, Gabriel O. Assunção, Marcos O. Prates, and I explore this in depth. jds-online.org/journal/JDS/... #DataScience #MachineLearning #ImbalancedData #AI #Oversampling

Tá insuportável isso aqui. O mais triste é que passaram a semana dizendo que hoje ia esfriar um monte.

Ran my text through ChatGPT arguing why oversampling usually doesn’t make sense, and it flipped my argument to support oversampling instead. A reminder that AI often defaults to consensus—even when it's wrong. Always double-check! #AI #MachineLearning #Statistics

Does anyone know of open data sources for air quality across different regions of Brazil? Weather forecasting websites show current conditions, but is this data being stored anywhere for future use? #Weather #AirQuality #OpenData #Environment #Statistics #Brazil

Testando threads e bluesky. Achei o bluesky muito melhor, mas está parecendo que o threads está tendo mais adesão dos brasileiros.
