I. BACKGROUNDOriginally intended to be based on the "DEX deep expectation of apparent-a single image" for the surface age training, can be due to the Imdb-wiki data set is large, uneven distribution of all ages, difficult to divide the training set and validation set. Later, in order to first run through the main part of the training process, directly with the lap data set, reference Caffe Finetune_flickr_style, some parameter modification, the use of Bvlc_reference_ Caffenet.caffemodel complete

Asp.net MVC, by default, only one model can be returned at a time. If multiple datasets are called, viewdata can only be used for export. It seems very troublesome, you can implement the model extension method ( declare that this method is only applicable to MVC2, and supports generic type after mvc3. It is very convenient to directly use viewbag to pass it over. ) First, define a class in the controller. The content is as follows: Public Class

Preferences are not measurable.Compared to other machine learning algorithms, the recommended engine output is more intuitive and easier to understand.The next three chapters mainly describe the main machine learning algorithms in Spark. One chapter revolves around the recommendation engine, which mainly introduces music recommendations. In the following chapters we first introduce the practical applications of spark and Mlib, and then introduce some basic ideas of machine learning.3.1 Data sets
