DeepKOALA service is unavailable temporarily

DeepKOALA is a high-performance deep learning-based tool for rapid protein function annotation according to the KEGG Orthology (KO) system. By framing KO assignment as an open-set recognition problem, it can effectively distinguish between known and unknown functional sequences, thereby reducing false-positive annotations. Built on a Gated Recurrent Unit (GRU) architecture, the tool provides excellent computational efficiency while ensuring high accuracy. This DeepKOALA runs on CPU machines.
