This period of time in learning Stanford iOS 8 teaching video, learning without thinking is idle, so prepare to summarize the video to learn some notes, so that they can deepen their understanding.Now I have learned 6 lessons, from these six lessons, the first section of the lecture is mainly about a calculator demo, and interspersed with a few iOS introduction, as well as the introduction of MVC. The fourth section mainly introduces some swift syntax

I. Introduction of the CourseStanford University launched an online natural language processing course in Coursera in March 2012, taught by the NLP field Daniel Dan Jurafsky and Chirs Manning:https://class.coursera.org/nlp/The following is the course of the study notes, to the main course ppt/pdf, supplemented by other reference materials, into the personal development, annotation, and welcome everyone in the "I love the public class" on the study together.Courseware Summary: The

Last night, my roommate White gave me an article mactalk the public, the author said no longer can not find such a speech, so full of passion, so give us a striking revelation, stay hungry, stay foolish, also become my next work life faith,If you are hungry, be foolish !I specifically found this Chinese-English version of Steve Jobs at Stanford graduate speech, give us a lesson, give us some enlightenment.=============================================

Such symbols are clearly divided in meaning, but in English.

,....} (A is the 1th word in the dictionary and Nip is the No. 35000 Word). So for naive Bayes, it can be expressed as the following matrix (the 1th element of the matrix is 1, and the No. 35000 element is also 1)in the multinomial event model, it is expressed as,. This means that the 1th word of the message is a, and the No. 35000 Word is nip. In this case, if the 3rd word in the message is a, the naive is unchanged, but the representation in the Multinomial event model will be x3=1. This allow

The second lesson of the Stanford iOS Development video was finished tonight, and the professor's homework was done.The professor's assignment is to expand on the existing card game app, so that random colors appear at each flop.In fact, this is very simple, that is, the class written by the Professor class to instantiate, while acquiring the specific contents of the card, that is, the contents attribute.Below I will put the finished app and app class

NSObject object, and the value is anyobject.then int, float, double, bool are all received from the NSNumber Bridge, NSNumber is OC in all about the value of the object, int, float, double these and C language int, float, double is also bridged good, So if the API has a C-language int parameter, it can also accept an int from SwiftOf course, if you are sure what data type you need, you can do type conversion. For example, length is a property of NSString, does not exist in string, it does not e

From ⅱ to IV, linear regression is used. Chapter II describes simple linear regression (SLR) (single variable ), chapter III describes the basis of line generation, and chapter IV describes multivariate regression (greater than one independent variable ). The purpose of this article is to implement some algorithms that appear in chapter II. Suitable for scholars who have already completed Stanford courses in this chapter. I am just a beginner and tr

little switch in the Inspector in the right side. That says initial scene.How do we get this thing in navigation controller? Ans:xcode | Editor | Embed in | Navigation controller, so another view Controller's going to appear, a Navigation controller. Notice that it's going to keep the arrow and it moves the arrow to itself. And then it had a little pointer right after It,which was not a segue. This little pointer in between are a special little connection in Xcode, which is the Rootviewcontroll

algorithm solves the problem of large optimization by decomposing it into several small optimization problems. These small optimization problems are often easy to solve, and the results of sequential solution are consistent with the results of solving them as a whole.The SMO works based on the coordinate ascent algorithm.1, coordinate ascentAssume that the optimization problem is:We select one of the parameters in turn to optimize this parameter, which causes the W function to grow fastest.The
