    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). …”

    Synthesis and optical properties of GaN nanowires by Chen, Xiaoxuan

    Published 2015
    “…We use LPCVD and silicon wafer to synthesis straight GaN nanowires.The parameters of the growth condition has been changed to gain the best results. PL and Raman spectroscopy has been used to study the optical properties of GaN nanowires.To further investigate the promising optical properties of GaN wire, power dependent and temperature dependent photoluminescence measurement is conducted on a nanolaser made by InGaN/GaN multiple quantum well nanowire. …”

    Optimal operation of combined cooling heat and power (CCHP) systems in future energy networks by Chen, Yumin

    Published 2017
    “…Besides, comparison and discussion were made on three separate scheduling modes of microgrid in order to find the best and most cost-saving mode. The results of calculation indicate that the model established in this paper could effectively reduce the operational costs. …”

    Value investing with machine learning: the South American market by Chen, Ye

    Published 2024
    “…The conclusion drawn is that a model with two layers, where the first layer has 200 neurons and the second layer has 100 neurons, exhibits the best performance. Such a model demonstrates satisfactory accuracy in predicting stock price trends for both large and small companies.…”

    Preparation and photocatalytic activities of Au-Fe2O3 hybrid nanoparticles by Chen, Hu.

    Published 2012
    “…For Au-Fe2O3, the sample prepared by PVP (polyvinylpyrrolidone, k value = 29-32) was selected for Au-Fe2O3 fabrication since this sample has the best photocatalytic performance. The second stage was the investigation on photocatalytic activities of the prepared samples. 5mg sample was dissolved in 10mL Methyl Orange with concentration of 5mg/L, which was then irradiated by a Xenon lamp (MAX 150W) for 4 hours; during the irradiation, 1.25mL sample was taken every 60 minutes for concentration detection. …”

    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. …”
