Route 53, Amazon’s Premier Database
I’ve periodically made reference in a bunch of places to Route 53 being my preferred database. But I’ve only really told the story in podcast and tweet

Trying to figure out why Gemini AI in Gmail is so very bad. It seems to not have access to all of my email and whatever RAG-like thing they are doing is very stupid.
Here's Gemini saying my oldest email matching some keywords in 2021 is from March 2021. If I explicitly tell it to look in February 2021, it finds it. There's only 11 emails that match in all of 2021, it's not like I'm blowing up the context window.

The moduli spaces of left-invariant statistical structures on Lie groups
In the context of information geometry, the concept known as left-invariant statistical structure on Lie groups is defined by Furuhata--Inoguchi--Kobayashi [Inf. Geom. (2021)]. In this paper, we introduce the notion of the moduli space of left-invariant statistical structures on a Lie group. We study the moduli spaces for three particular Lie groups, each of which has a moduli space of left-invariant Riemannian metrics that is a singleton. As applications, we classify left-invariant conjugate s…

Frequency-Aware Ensemble Learning for BraTS 2025 Pediatric Brain Tumor Segmentation
Pediatric brain tumor segmentation presents unique challenges due to the rarity and heterogeneity of these malignancies, yet remains critical for clinical diagnosis and treatment planning. We propose an ensemble approach integrating nnU-Net, Swin UNETR, and HFF-Net for the BraTS-PED 2025 challenge. Our method incorporates three key extensions: adjustable initialization scales for optimal nnU-Net complexity control, transfer learning from BraTS 2021 pre-trained models to enhance Swin UNETR's gen…

Ergodic Properties of Quantum Markov Semigroups
In this paper, we study the ergodic theorem for infinite-dimensional quantum Markov semigroups, originally introduced by Frigerio and Verri in 1982, and its latest version developed by Carbone and Girotti in 2021. We provide a sufficient condition that ensures exponential convergence towards the positive recurrent subspace, a well-known result for irreducible quantum Markov semigroups in finite-dimensional Hilbert spaces. Several illustrative examples are presented to demonstrate the applicatio…
