Projects Details

AI for an Eye   

In this project, we propose a CNN-based model to help pedestrian crossing intersections. The model consisted of traffic light detection and recognition, street width assessment, and obstacles evaluation. We also collected images and constructed a labeled database to train and test our model. By recognizing pedestrian traffic lights, estimating an appropriate time to cross, and detecting dangerous objects on the walking path, users could know whether a crossing is safe to walk.

PTT Web Crawler

Crawled contents on PTT C_Chat Board, which contained users votes for favorite animates of the 2019. Conducted html parsing, data crawling, cleansing, collecting and visualizing to present the result. During the process of data processing, there was a special need to decode the self-protected email format, which was an obstacle due to unique "push" content. The data visualization was performed by Power BI.

The Trade War Effects  

Analysis on how and what the US-China trade war would affect multinational businesses. The most severe and clear result was the swift transformation of production lines. Factories in China will evacuate and move to the nearby Southeast Asian countries, e.g. Vietnam, Cambodia, etc. Besides, some industries such as the high-tech industry in Taiwan will also receive benefits because of the Trade War.
