AIST Solutions: Joint Research on a Domestic Image Generation AI Model Designed to Minimize Rights Risk
In collaboration with AIST Solutions, part of the AIST Group, this joint research focuses on developing a domestic image generation AI model with minimized rights-related risk. By combining Formula-Driven Supervised Learning (FDSL) with rights-cleared image data, the project enables transparent training and commercially usable foundation model development.
Drone Filming Data Provision for Advanced Drone Development by a Domestic Aircraft Manufacturer
Supporting UAV development for a domestic aircraft manufacturer, the project delivered specialized drone filming data using spectral and HDR cameras for advanced marine condition analysis. From port and vessel access coordination to expert sensor operations, the initiative enabled high-difficulty data acquisition under complex technical, environmental, and project constraints.
Emotional Speech Data Provision for Inappropriate Speech Detection AI at a Major Telecommunications Carrier
Capturing authentic emotional speech data for customer harassment scenarios, including angry shouting and tense vocal states, is highly challenging. This project addressed speaker attribute bias, supported detection model accuracy, and integrated consent management, log retention, and commercial rights clearance into a single workflow for compliant, high-quality AI training data delivery.
Emotion Recognition Speech Data Provision Covering Age Groups from Preschool Children to Adults
The project secured hard-to-source emotional speech data across age groups, including preschool children, and delivered clean, model-ready datasets through studio recording, emotion-based segmentation, and noise reduction. Enabling more robust training and evaluation for emotion recognition AI.
Diverse Data Provision for High-Performance Image Generation AI in IT and Telecommunications
Improving image generation AI in specialized scenarios, the project curated high-resolution, rights-cleared data from over 240 million assets, including night scenes, backlit conditions, and macro imagery. Combining large-scale library access, 4K-quality supply, and structured metadata design, it reduced lead time, removed legal bottlenecks, and supported higher-quality model development.
