Prototypical networks for few-shot learning引用
WebbFew-shot sequence labeling is a general problem formulation for many natural language understanding tasks in data-scarcity scenarios, which require models to generalize to new types via only a few labeled examples. Recent advances mostly adopt metric-based meta-learning and thus face the challenges of modeling the miscellaneous Other prototype … WebbThe few-shot learning models struggle to perform consistently on MUV and DUD-E data, in which the active compounds are structurally distinct. However, on Tox21 data, which is typically used for lead optimisation, the few-shot ML models perform well and our contribution of the Prototypical Networks even outperforms the state of the art.

WebbUsing the episode-known dummies, we propose Dummy Prototypical Networks (D-ProtoNets). For few-shot open-set keyword spotting (FSOS-KWS), we introduce a benchmark setting named splitGSC, a subset of GSC ver2. Our D-ProtoNets achieves state-of-the-art (SOTA) performance in splitGSC. Webb15 apr. 2024 · Few-shot learning has been used to tackle the problem of label scarcity in text classification, of which meta-learning based methods have shown to be effective, such as the prototypical networks (PROTO). Despite the success of PROTO, there still exist three main problems: (1) ignore the randomness of the sampled support sets when computing …
