Improving machine learning predictions to estimate fishing effort using vessel's tracking data
Published 2025-03-01“…Temporal resolution (ping rate) showed minimal effects on model performance, ranging from less than 2 % for intervals between 30 s (raw data with irregular time series) to 10 min (regular time series). As a post-processing step, it was concluded that replacing isolated data points with neighbouring values, significantly enhanced the detection of fishing events, with improvements ranging from 80 % to 250 %, depending on the model.In conclusion, this study presents a straightforward procedure for selecting a machine learning method and enhancing its power of classification using simple procedures. …”
