    TFIDF meets deep document representation : a re-visit of co-training for text classification by Chen, Zhiwei

    Published 2020
    “…In this paper, we conduct exper- iments to evaluate the effectiveness of co-training with different combina- tions of document representations (e.g., TFIDF, Doc2vec, ELMo, BERT) and classifiers (e.g., SVM, Random Forest, XGBoost, MLP, and CNN) on two benchmark datasets (20 Newsgroup and Ohsumed). …”

    Direct observation of resonant energy transfer in lanthanide complexes from multidisciplinary perspectives by Chen, Xuebo

    Published 2020
    “…However, in special case incorrect arguments and formulae were often employed by ignoring energy resonance conditions and selection rules of state-to-state transition, especially for the sensitive intramolecular EnT of lanthanide complexes bearing a uniform donor-acceptor distance. Herein, we proposed an innovative model of energy degeneracy crossing controlled EnT, which can be experimentally confirmed by a bi-exponential decay using the time-resolved photoluminescence measurements. …”
