descriptionAdvantages:(1) There is no need for large-scale users (like collaborative filtering) to get the relationship between items(2) Once the property of the item is obtained, the item can be recommended to the user immediately.3. Knowledge-based recommendationsIn some areas, such as the consumer electronics sector (e.g), the vast majority of data is a single purchase record. If you apply both of these methods, the data is too sparse to even get the recommended results. What if we have to r

understand, seemingly and the above--when a feature OK, use this feature; , the weaker features are used2. Parallel hybrid design Multiple recommendation engines, how to fuse together? 2.1 Cross-mixing multiple results of multiple recommendation engines, cross-merge into one result: first engine first result ranked first, second engine first result ranked second ... 2.2 Weighted mixed linear weighted combination, one weight per engine, weight normalization 2.3 switching mix when in some cases w

Basic idea: The data is divided into training set and test set, training model with training set data, test model with test set data. The Division of Training set and test set can be by the dimension of time, or by the dimension of the crowd. Risk: There may be biases for some methods.Using historical data to evaluate the data into training set test set and N-fold cross-validation according to Time dimension.There is also the direct use of human evaluation. However, the cost is larger, not on th

too advanced. Some tips can be used for reference when dealing with road data in the future. 3) in this paper, this problem is difficult to solve, but the author puts forward restrictions and simplifies step by step to make the problem easy to solve; for example, the time complexity of finding a route is n ** (M-1), but the author proves that when m is greater than 4, the yield growth rate is less than 10%, for taxi drivers, it is recommended that further road sections do not have much value, t

of k = 0, because we do not need to add x=1 this element manually. If X=1 is needed, the collaborative filtering algorithm will calculatea x=1. The algorithm description ends here. So, why is this algorithm called Matrix decomposition algorithm? See, we convert the y matrix to the product of Theta and x two matrices. 　　So, how to find the most similar to movie I 5 movie it? Calculate Distance: the distance may be very large. Better computing distances or similar

problem, as long as the server can be good.SomethingHere just put forward one of their own ideas, the process of thinking is also seen in many of the relevant academic literature recommendation system and carried out their own summary and change, not authoritative approach, welcome to propose amendments.Heard a few years ago, ACM has an annual recommendation system for the academic conference called Recsys, interested in the small partners can also pay attention to.Have a question welcome priva

algorithm, and consider the bias algorithm to achieve a, the data source is from Movielens 100k data, which contains 1000 users of 2000 items of the score (of course, I am here is directly open the array, If the amount of data is larger, it will not be implemented, mainly to verify the effect of a gradient drop, using the base data set to train the model, test data set for testing, the effect of evaluation with a formula to measure:To be blunt is the sum of squared errors ... We also document t

[Project Record]-on-site car washing-vehicle service and car washing Service 　　 The project was launched in July September 2015. The public account was initially required to make an on-site car wash reservation, which can be paid online and in-person cash. Before that, they used to make an appointment to wash the car by phone. Reservation: use the technology background spring + struts2 + jdbc, And the foreground is jquerymobile + bootstrap. The icon u

I. Overview of Intelligent Transportation Technology The Intelligent Transportation System (Intelligence Transport System, its) is a frontier research topic in the World transportation field, which integrates the theories of electronic information technology, communication technology, automatic control theory, computer technology and traditional transportation engineering theory, And it is applied in the modern transportation management system, so as to realize the transportation service and man

Vehicle Rule SYSTEM INTRODUCTION I. Overview The driving rule, that is, the driving specification, is a kind of driving specification for vehicles and drivers. The driving rule is divided into two modules: Rules and subsequent handling. Subsequent handling is the prompt, handling, and operation after violation of the rules. The rules include non-work-time vehicle alert, regional alert, regional alert, rout
