The document discusses hyperparameter optimization in machine learning models. It introduces various hyperparameters that can affect model performance, and notes that as models become more complex, the number of hyperparameters increases, making manual tuning difficult. It formulates hyperparameter optimization as a black-box optimization problem to minimize validation loss and discusses challenges like high function evaluation costs and lack of gradient information.
This document discusses methods for automated machine learning (AutoML) and optimization of hyperparameters. It focuses on accelerating the Nelder-Mead method for hyperparameter optimization using predictive parallel evaluation. Specifically, it proposes using a Gaussian process to model the objective function and perform predictive evaluations in parallel to reduce the number of actual function evaluations needed by the Nelder-Mead method. The results show this approach reduces evaluations by 49-63% compared to baseline methods.

我々の身近には最適化された・するモノ・コトが多々存在する。これらモノ・コトはどのように最適化されたのだろうか。具体例をもとに最適化問題について説明し、進化的計算による最適化アルゴリズムについて説明する。
There are many optimized things/items in our real world. How were these things optimized? Explain the optimization problem based on a specific example and explain the optimization algorithm by Evolutionary computation.
Randomized smoothing is a method to make a classifier robust against adversarial attacks. I introduce two papers to improve the performance of a method using randomized smoothing technique.

Este documento presenta una técnica para estimar el volumen de un conjunto E en Rn mediante el uso de muestras aleatorias. Se define una cantidad ε*q(E) que representa el radio máximo de una bola centrada en una muestra que está completamente contenida en E. Se demuestra que cuando el número de muestras tiende a infinito, ε*q(E) converge a una cantidad relacionada con el volumen de E.
I mede this slide for the beginners of object detection.
Anchor box was really hard to understand for me, so I wrote about it as easy to understand as I can.
Let's overwhelmingly prosper!!
