代码说明:

首先给出了社交网络中热点话题趋势预测的形式化定义和一个话题趋势预测模型,然后提出了一种针对时间序列数据进行特征抽取和构造的新方法,基于提出的新方法构造了三个相互补充的特征子集,最后将这三个特征子集线性组合起来做为支持向量机的输入向量进行话题趋势的预测。为了验证预测模型的性能,本论文釆集了一个高质量的新浪微博数据集。基于获取到的数据,对预测模型进行了完整的测试,取得了良好的效果。

    A commented bash script to generate our final 2nd place solution can be found in make_kaggle_solution.sh. Running all the commands sequentially will probably take 7 - 10 days on recent consumer grade hardware. If you have multiple GPUs you can speed things up by doing training and feature extraction for the two networks in parallel. However, due to the computationally heavy data augmentation it may be far less than twice as fast especially when working with 512x512 pixel input images. You can also obtain a quadratic weighted kappa score of 0.839 on the private leaderboard by just training the 4x4 kernel networks and by performing only 20 feature extraction iterations with the weights that gave you the best MSE validation scores during training. The entire ensemble only achieves a slightly higher score of 0.845.
