Dataset Initialization and ConfigurationThe data pipeline begins by instantiating the NuScenes API to manage scene metadata. The SegmentationData class orchestrates the separation of training and validation splits. It invokes logic to generate lists of scene tokens, separating them based on predefin...
Real-world datasets are rarely ready for immediate model training. They frequently contain missing values, inconsistent formatting, and significant noise or outliers. When algorithms process low-quality input, the resulting predictions degrade substantially. Preprocessing transforms raw information...
Data discretization is the process of partitioning continuous attributes into a finite number of intervals, effectively mapping infinite numeric spaces into discrete categories. This transformation is fundamental in data preprocessing, especial when dealing with algorithms that require categorical i...
Raw data loaded directly from storage is rarely formatted correctly for direct neural network training. MindSpore provides a suite of modular transform operations that integrate with data processing pipelines via the map method, supporting image, text, and audio preprocessing alongside custom user-d...
