Poetry / Seichiro POETRY
I have been writing poetry for about twenty years.
I have been exploring what it means to love myself
and be kind to myself.
But the words I wrote were not all clear to me
from the very beginning.
Through my own struggles, little by little,
I have come to understand their meaning.
What I want to cherish is not love that sacrifices the self,
but love that naturally overflows when we care for our own hearts.
And I value the works themselves, in ways that play counts alone cannot measure.
An encounter with AI turned my poetry into music.
I hope they help you remember to care for yourself.
These are words and songs I truly cherish and love.
02 / AI PROJECTS
Let AI support what matters to people.
Remember. Learn. Express. Connect.
Nurturing what matters to people, together with AI.
FeatherTune explores four themes.
Exploring systems for AI memory that keep important information from being forgotten. This includes ways to build on knowledge and conversations, including meetings among multiple agents.
MEMORY & MULTI-AGENTCourses for understanding and using AI. This learning initiative brings new technology closer and explores how to make it part of your own activities.
LEARNING & DISCOVERYA project to discover the appeal of AI music while checking for similarity to, and reliance on, existing works. We value both creative possibilities and a thoughtful approach to each work.
MUSIC & EXPLORATIONThese checks do not constitute a legal determination or guarantee clearance of rights.Linking people and records in everyday project management.
