localization_optimization_using_machine_learning
indoor/outdoor classification. GPS positioning is generally more accurate when outdoors, but there is no GPS information indoors, therefore, other methods should be taken, such as Wi-Fi/ Bluetooth positioning, or base station positioning. However, for the gray areas between indoor and outdoor, many indoor scenes will also have GPS information. At this time, indoor/outdoor classification is required, because indoor and outdoor scenes mean different strategies applied for positioning and navigation, accurate indoor/outdoor classification could provide better positioning and navigation performance and user experience. This project is to extract GPS features from big data, and use machine learning algorithms, then train models to classify indoor and outdoor situations.
big_data_analysis_for_BaiduMaps
Monitor the localization performance and user experience of Baidu Maps. The basic statistical indicators include the PV (page views), UV (unique visitors), different usage methods such as outdoor / indoor, navigation by drive and walk, etc. The complex statistical indicators are the accuracy and success rate of localization, which generally needs to be sampled according to area and time. Then establish a database to store those results every day, and finally data visualization is necessary for daily checking.
