结合随机森林和LSBoost进行证券市场指数预测。 Abstract— This research work emphases on the prediction of future stock market index values based on historical data. The experimental evaluation is based on historical data of 10 years of two indices, namely, CNX Nifty and S&P Bombay Stock Exchange (BSE) Sensex from Indian stock markets. The predictions are made for 1–10, 15, 30, and 40 days in advance. This work proposes to combine the predictions/estimates of the ensemble of trees in a Random Forest using LSboost (i.e. LS-RF). The prediction performance of the proposed model is compared with that of well-known Support Vector Regression. Technical indicators are selected as inputs to each of the prediction models. The closing value of the stock price is the predicted variable. Results show that the proposed scheme outperforms Support Vector Regression and can be applied successfully for building predictive models for stock prices prediction.

马尔可夫随机场在图像去噪中的应用 这是一个有关在Keras中应用Markov随机场(MRF)进行图像降噪的项目。 在Report.pdf中显示了在MRF中构建修改的迭代条件模式(ICM)和Gibbs采样的机制的详细信息。 数据 应用于降噪和降噪的原始数据集可以分为两部分: 二进制图像:在这种情况下,选择两个具有低分辨率的二进制图像:data / sample1.jpg,data / sample3.jpg来比较ICM和Gibbs采样以在MRF中进行降噪。 RGB图像:此外,选择了分辨率较低的RGB图像:data / sample6.jpg来比较ICM和Gibbs采样,以在MRF中对更复杂的数据结构情况进行降噪。 图像噪声: 在该项目中,图像受到胡椒噪声的干扰,其中选择了随机位置的像素以将其重置为随机有效值。 详细地,对于具有单通道的二进制图像,在唯一的层中添加了胡椒噪声。 而对于具有
