Forest inventory forms the foundation of forest management. Remote sensing (RS) is an efficient means measuring parameters at scale. Remotely sensed species classification can be used to estimate abundances, distributions, and better approximate metrics such as above ground biomass. State art methods RS rely on deep learning models convolutional neural networks (CNN). These have 2 major drawbac...

Large-scale high-throughput sequencing techniques are rapidly becoming popular methods to profile complex communities and have generated deep insights into community biodiversity. However, several technical problems, especially sequencing artifacts such as nucleotide calling errors, could artificially inflate biodiversity estimates. Sequence filtering for artifact removal is a conventional meth...
