说明：  完成一个基于q-learning算法的简单寻径实例(A simple path finding example based on Q-learning algorithm is completed)

说明：  从数据库获取车辆在一段时间内的所有行驶记录的相关数据，确定所需数据为GPS经纬度坐标和驾驶时长等，QB模型采用MDF的思想,其基本思想为:通过平均直接翻转距离函数定义两条轨迹之间的距离，两条轨迹需要具有相同的经纬度点数，具有相同点数的轨迹最大的优点是对轨迹距离成对计算，且相同轨迹之间具有更高的分辨率，对于轨迹聚类的结果有一定的优化。(Retrieved from the database cars all over a period of time, record the related data, determine the required data for the GPS latitude and longitude coordinates, and the driving time, QB model by adopting the idea of MDF, its basic idea is: flip directly by the average distance function definition of the distance between two trajectories, two tracks will have the same latitude and longitude points, and has the biggest advantages of the same points of trajectory track distance calculation in pairs, and has higher resolution, between the same trajectory for trajectory clustering results have certain optimization.)

说明：  卷积网络正在推动着图像识别方面的进步，其不仅改进了整体图像的分类效果，而且在具有结构化输出的局部任务上也取得了进步，包括边界框目标检测，关键点预测等。 自然下一步是改进在像素级别上的预测。其实，以前的方法已经使用卷积网络进行语义分割任务，其中每个像素都被标记为属于目标或属于其他区域，但让具有缺点。 FCN和CNN的区别：CNN卷积层之后连接的是全连接层；FCN卷积层之后仍连接卷积层，输出的是与输入大小相同的特征图，提出一个端到端，像素对像素的全卷积网络用于语义分割任务(Convolution network is promoting the progress of image recognition. It not only improves the classification effect of the whole image, but also makes progress in the local tasks with structured output, including boundary box target detection, key point prediction and so on. The natural next step is to improve prediction at the pixel level. In fact, previous methods have used convolutional networks for semantic segmentation tasks, in which each pixel is marked as belonging to the target or other regions, but it has disadvantages. The difference between FCN and CNN: CNN convolution layer is connected with full connection layer after CNN convolution layer; FCN convolution layer is still connected with convolution layer after FCN convolution layer, and the output is the same as the input size of feature map. An end-to-end, pixel to pixel full convolution network is proposed for semantic segmentation task)
