 ===== NEEMS Lecture: 2. Data Preparation =====
-In the [[https://ease-crc.org/material/ease/machinelearning/visualizing_the_data|previous section]] we started off by visualizing the NEEMS data as pie-charts and tables. This section is about preparing the data for training, including filling empty data cells, transforming the data in one-hot-encoding and shrinking down the tables to the relevant bits.
