NIST Pre-Pilot Datascience Evaluation

We participated in the Pre-pilot data science evaluation organized by the National Institute of Standards and Technology (NIST), the primary goal which is to develop and exercise the evaluation process in the context of data science. The evaluation consists of four tasks including data cleaning, data alignment, forecasting and prediction. Our DSR lab has participated the data cleaning and traffic event prediction tasks, and submitted several running systems (most of which are based on student projects in our data science class) of different algorithms and configurations. In the data cleaning task, we are given a set of detector measurements (see Figure 1 for detector distribution) for vehicle velocity, lane occupancy and flows. Among the given measurements, part of the values are incorrect (e.g. added noises by an artificial program), and…
