用连续小波对信号进行多尺度变换，选择合适的小波系数，采用模极大值检测RQS波群。-Using continuous wavelet multi-scale transform of signal, the appropriate wavelet coefficients, using modulus maxima detection RQS wave group.

LightLDA is a distributed system for large scale topic modeling. It implements a distributed sampler that enables very large data sizes and models. LightLDA improves sampling throughput and convergence speed via a fast O(1) metropolis-Hastings algori

2018年甜橙金融杯大数据建模大赛初赛方案：通过追踪时间、设备、ip和经纬度等属性的变化来建模判断UID是否为黑产链 ## 代码说明： - gen_stat_feat.py 统计特征 - gen_w2v_feat.py word2vec特征 - lgb_train.py lgb训练模型 两份特征建模加权8:2比例融合即可0.792+，单独统计特征加UID列建模即可0.795。(The preliminary scheme of the 2018 Sweet
