Harmful Algal Blooms Prediction Model: Dealing With Limited Datasets

HABs pose serious threats to natural aquatic systems, such as mass mortality of aquatic organisms, degradation of water quality, and human poisoning from consuming aquatic organisms exposed to HABs. Monitoring water quality and weather data through buoy data loggers is very useful nowadays. Through these buoys, environmental data can be accessed in real time. Various technical constraints on these buoys will directly and indirectly result in missing values (limited data sets). It often happens that one has a good idea of a learning model, but due to its complexity and smaller number of data sets, the model performs far below expectations. Transfer learning approaches and data synthesis with the CT GAN algorithm have been applied to deal with modelling on limited datasets. The transfer learning model gives better results. It can be seen from the value of model evaluation parameters (AUC and MSE) that the transfer learning model provides better results than other models (model-based CTGAN and deep learning model without transfer learning). The process of adapting (fine-tuning) knowledge is an important process in improving the performance of the model in the transfer learning procedure.
