Hello, I'm

Hiroto Ishii


I'm a fourth-year Management and Information student building practical software and machine learning systems. My focus is turning vague ideas into working prototypes: data-driven applications, neural network experiments, and tools that make technical concepts easier to use.

/ Career

A brief overview of my career

Apr 2023 - Present

BSc Student, Management and Information

University of Shizuoka

Studying information systems, programming, data analysis, and management. Currently working on a graduation research project around neural network training dynamics and parameter sharing.

Machine LearningData AnalysisC++Python
2025 - Present

Neural Network Research Project

Graduation Research

Implementing and evaluating neural network structures that begin with shared parameters and gradually differentiate during training. Building experiments in C++/Python and comparing learning behavior against independent-neuron baselines.
