Note that, in what follows, all TensorFlow operations have a name argument that can safely be left to the default of None when using eager execution as its purpose is to identify the operation in a computational graph.Note that this is equivalent to np.mean, except that it infers the ...

I don’t know what you mean by “more robust”. If I understand the method he is using correctly, then it minimizes the RMS error between corresponding points from either point cloud. It can accept any pair of ordered point clouds (of the same size), regardless how similar they are to...
ClassLine()can help to improve the performance of lane lines detection by the method of calculating the mean of last n(9 settled) found fits, which can smooth and stabilize the lane lines moving.
For setting the prior mean function: when calling fit(), pass in a vector mu0 that is the same size as item_features. Each entry of mu0 is the prior preference function mean for the corresponding item in item_features when calling predict_f() to predict the score for test items, or ...
