Expert’s cases:

  1. Led a project on the collection of driving data for ADAS/AD development. (4 team members)

    • Developed a system capable of collecting data from Lidar, cameras, GPS, and other sensors. This system plays a crucial role in the Data-Driven Development (DDD) pipeline of ADAS/AD and the collected data will be used for AI training, virtual validation, and scenario generation.

    • This system enabled data measurement with a simple structure, which reduced the cost of dSPACE GmbH’s measurement system by 80%.

  2. Worked on the development of AI image detection models.

    • Conducted research on image detection AI and successfully developed several AI models capable of detecting custom items. Established a whole process from image collection, labeling, and model training. The cost of outsourcing any model is about $50,000.

    • Utilized AI models to tag large amounts of data, enabling quick and efficient data retrieval.

    • Presented research findings at oral conferences.

  3. Utilized AI tools to drive Digital Transformation (DX) within the company.

    • Investigated the utilization of generative AI, specifically ChatGPT, for the development of a support chatbot.

    • A local generative AI similar to ChatGPT is being set up. If successful, it could save 50% support time.

  4. Successfully completed a project for a sports manufacturer using the Japanese version of BERT.

    • Conducted sentiment analysis with and without user benefits using the Japanese version of BERT.

    • Made modification to improve the verification accuracy rate of the model.

  5. Developed a Chinese version of the BERT model for a project with an electric machine manufacturer.

    • Conducted survey, implementations and sentiment analysis reasoning confirmation using the Chinese version of BERT

    • Analyzed reviews on a Chinese e-commerce site for a certain electrical equipment manufacturer
