Stanford iOS Learn Notes, stanfordios During this time, I was studying Stanford's iOS 8 teaching video, so I was not thinking about it, so I was prepared to summarize some notes about the video learning so that I could understand it more easily. Now I have learned six lessons. From these six lessons, the first three lessons mainly focus on a Demo of Calculator and interspersed with a few iOS introductions, and MVC introduction. Section 4 mainly intr

two classification problem, so the model is modeled as Bernoulli distributionIn the case of a given Y, naive Bayes assumes that each word appears to be independent of each other, and that each word appears to be a two classification problem, that is, it is also modeled as a Bernoulli distribution.In the GDA model, it is assumed that we are still dealing with a two classification problem, and that the models are still modeled as Bernoulli distributions.In the case of a given y, the value of x is

. The data source does not deal with such things as would and should, he answers how many songs there are and returns the quantity to the view. The view now opens up space for these 10,000 songs. So the function of the controller (C) is to interpret and format the data provided by these models (M) for the View (V).So the question comes again, can the model communicate with the controller? Obviously not. But suppose the data changes how to notify our controllers? It still uses this method of blin

default is to use a hidden layer is a reasonable choice, but if you want to choose the most appropriate layer of hidden layer, you can also try to split the data into training sets, validation sets and test sets, and then try to use a hidden layer of neural network to train the model. Then try two, three hidden layers, and so on. Then see which neural network behaves best on the cross-validation set. That means you get three neural network models, one, two, and three hidden layers, respectively

unreasonable. That is, in the past two months the word has not appeared in the mail, it is considered that the probability of 0, unreasonable.Generally speaking, it is unreasonable to think that these events will not happen if they have not been seen before . Solve this problem with Laplace smoothing.4. Laplace SmoothingAccording to the maximum likelihood estimate, p (y=1) = # "1" s/(# "0" s + # "1" s), that is, the probability of Y being 1 is the ratio of the number of 1 in the sample to all s

Model,view no model-oriented broadcasts, and the view and controller will broadcast to each other.The model broadcast is very useful because it is not visible, but there are restrictions that can only notify the object that is allowed to notify what happened.(7) 1 model only 1 controllers.Can a controller have a view conversation with someone else? Normally the controller will have a pointer pointing to another controller as the view, which will require the controller to display the object. So,

This question can be done by using the theory of finite automatic machines. You can also enumerate possible situations and jump to the status after setting various States. For example, if a sentence has ended, this state is set to 0, in the word
