LOGOS-CA: A Cellular Automaton Using Natural Language as State and Rule
Keishu Utimula
Large Language Models (LLMs), trained solely on massive text data, have achieved high performance on the Winograd Schema Challenge (WSC), a benchmark proposed to measure commonsens…
A Model of Silence, or the Probability of "Un Ange Passe"
Keishu Utimula
In French, the phrase "Un ange passe" ("An angel passes") refers to the sudden silence that falls over a co-present group -- that is, a group of people sharing the same physical sp…
Artificial Life using a Book and Bookmarker
Keishu Utimula
Reproduction, development, and individual interactions are essential topics in artificial life. The cellular automata, which can handle these in a composite way, is highly restrict…
Application of canonical augmentation to the atomic substitution problem
Genki I. Prayogo, Andrea Tirelli, Keishu Utimula +3
A common approach for studying a solid solution or disordered system within a periodic ab-initio framework is to create a supercell in which a certain amount of target elements is…
Using reinforcement learning to autonomously identify sources of error for agents in group missions
Keishu Utimula, Ken-taro Hayaschi, Trevor J. Bihl +2
When agents swarm to execute a mission, some of them frequently exhibit sudden failure, as observed from the command base. It is generally difficult to determine whether a failure…
Feature space of XRD patterns constructed by auto-encorder
Keishu Utimula, Masao Yano, Hiroyuki Kimoto +3
It would be a natural expectation that only major peaks, not all of them, would make an important contribution to the characterization of the XRD pattern. We developed a scheme tha…
Intrinsic Electronic Defect States of Anatase using Density Functional Theory
Abhishek Raghav, Adie Tri Hanindriyo, Keishu Utimula +3
In this work an overall electronic structure including the position and formation energies of various intrinsic defects are computed for anatase using Density Functional Theory aid…
Quantum annealing approach to Ionic Diffusion in Solid
Keishu Utimula, Tom Ichibha, Genki I. Prayogo +3
We have developed a framework for using quantum annealing computation to evaluate a key quantity in ionic diffusion in solids, the correlation factor. Existing methods can only cal…
First Principles Calculations of Superconducting Critical Temperature of ThCrSi-Type Structure
Gewinner Senderanto Sinaga, Keishu Utimula, Kousuke Nakano +2
High critical temperature (T) superconductor has a great potential in many industrial applications. However, discovering a compound having high T is still remaining a big c…
Stochastic estimations of a total number of classes for the clusterings with too enormous samples to be accommodate into a clustering engine
Keishu Utimula, Genki I. Prayogo, Kousuke Nakano +2
We considered the problem how to handle the exploding number of possibilities to be sorted into irreducible classes by using a clustering tool when its input capacity cannot accomm…
search of polymer crystals with high thermal conductivity
Keishu Utimula, Tom Ichibha, Ryo Maezono +1
Lattice thermal conductivities (LTC) for a subset of polymer crystals from the Polymer Genome Library were investigated to explore high LTC polymer systems. We employed a first-pri…
Machine learning clustering technique applied to powder X-ray diffraction patterns to distinguish alloy substitutions
Keishu Utimula, Rutchapon Hunkao, Masao Yano +5
We applied the clustering technique using DTW (dynamic time wrapping) analysis to XRD (X-ray diffraction) spectrum patterns in order to identify the microscopic structures of subst…
