【债券回购量化投资模型】：本人在投资公司做量化投资的，分享一个简单的债券回购量化投资模型，在rar压缩文件附有数据，模型的原理与策略系历史最大开盘价合约进场，细节不多讲，做量化投资的朋友可以了解一下。([Bond repurchase quantitative investment model]: I do quantitative investment in investment companies, sharing a simple bond repurchase quantitative investment model, rar compressed files with data, principles and strategy of the largest in the history of opening contract model approach , not much talk about the details, do the quantitative investment friends can look at.)

DTW（Dynamic Time Warping，动态时间归整）算法，该算法基于动态规划（DP）的思想，解决了发音长短不一的模板匹配问题，是语音识别中出现较早、较为经典的一种算法。用于孤立词识别，DTW算法与HMM算法在训练阶段需要提供大量的语音数据，通过反复计算才能得到模型参数，而DTW算法的训练中几乎不需要额外的计算。所以在孤立词语音识别中，DTW算法仍然得到广泛的应用。 (DTW (Dynamic Time Warping, dynamic time warping) algorithm based on dynamic programming (DP) ideas, sounds of varying lengths to solve the template matching problem, is speech recognition appeared earlier, more classic kind of algorithm. For isolated word recognition, DTW algorithm and HMM algorithm in the training phase need to provide a large number of voice data, obtained by repeated calculations to model parameters, while the DTW algorithm is almost no additional training calculations. Therefore, in isolated word speech recognition, DTW algorithm is still widely used.)
