The port of Shanghai spanning over 1,000 years, was where the Ming’s naval expeditions were launched and was place of hectic trading, where fortunes were made and lost. My parents are both civil engineers and my childhood was spent on this unique river and Deepwater port, witnessing the harbour sweep into a grandiose showpiece of a booming economy. I watched basic structures integrated piece by piece and eventually form spectacular architectures.

Time spent in wonderment propelled me to join structural contest throughout middle school, where we analysed the load-bearing of structures and built the most reliable “building” out of paper boards. In high school, I learnt Integrated Circuit Design and started programming. In fact, I found …show more content…

We used D3.js to implement Chord Diagram, Parallel Coordinate, and also visualized the route of a mobile robot patrolling the building. Though there were hundreds of HVAC attributes, I suggested using PCA to reduce the dimensionality before visualizing the data, which turned out to solve the problem of visual clutter. By visualizing these data, employee behavior was displayed as a trend with abnormal events illustrated from the dataset.

HealthViz was another visualization system that I built in Yelp Dataset Challenge, by which I won the first prize at Hackathon UST. This was the first time that Yelp Dataset Challenge provided image data and corresponding labels. However, I recognized there was a mismatch between the imageID and textInfoID. In order to solve this, I crawled the image data online, manually labeled health index on thousands of them, and applied data augmentation and CNN to construct a health index for each restaurant. I also applied a Recurrent Neural Network, more specifically LSTM, on the review text, which is around 5 gigabytes, to compute sentiment score for each restaurant. With the aid of cloud computing tool Spark, we were able to finish the task very efficiently. The final visualization system included a map view that embedded a Heatmap of averaged health index across the US, a Wordle that visualize the most frequent
