Abstract The titanic dataset gives the values of four categorical attributes for each of the 2201 people on board the Titanic when it struck an iceberg and sank. The attributes are social class (first class, second class, third class, crewmember), age (adult or child), sex, and whether or not the

most of the researches on PV power generation forecasting methods have problems such as long time for model training and propose an optimization. Using the BP(backpropagation) neural network, this learning algorithm is mainly applicable to multi-input, multi-output networks. It can rely on ready-mad

这个数据集是自己制作的铁轨裂纹数据集，使用LabelImg软件自己标注的，格式为VOC2007。数据集图片共14010张。这是第二部分，第一部分请下载另外一个压缩包，即VOC2007第一部分。
