regression solver

Logistic regression (Logistic regression) is a common machine learning method used in the industry to estimate the possibility of something. For example, a user may buy a product, a patient may suffer from a disease, and an advertisement may be clicked by the user. (Note: "possibility", not the "probability" in mathematics. The result of logisitc regression is no

1. PrefaceThe linear regression form is simple and easy to model, but it contains some important basic ideas in machine learning. Many of the more powerful non-linear models (nonlinear model) can be obtained by introducing hierarchies or high-dimensional mappings on the basis of linear models. In addition, because the solution of linear regression \ (\theta\) intuitively expresses the importance of each att

Logical regression: It can be used for probability prediction and classification, and can be used only for linear problems. by calculating the probability of the real value and the predicted value, and then transforming into the loss function, the minimum value of the loss function is calculated to calculate the model parameters, and then the model is obtained.

Solver is the core of Caffe, which coordinates the operation of the whole model. One of the parameters required to run the Caffe program is the Solver configuration file. Running code is typically#caffe Train--solver=*_solver.prototxtIn deep learning, it is often loss function is non-convex, there is no analytic solution, we need to solve by the optimization meth

Caffe in training, need some parameter setting, we usually set these parameters in a file called Solver.prototxtThere are some parameters that need to be computed and not randomly set.Assuming we have 50,000 training samples, Batch_size is 64, which is 64 samples per batch, we need to iterate 50000/64=782 times to process all the samples. We have finished processing all the samples, called Generations, epoch. So, the test_interval here is set to 782, which means that once all the training data h
