So, what does "user research" include what work content, how to carry out in the enterprise, what to pay attention to in the implementation process? This article unifies the personal experience, does a simple analysis and

user requirements. The difference is that the analysis of user requirements is described using models to obtain more specific user requirements. To analyze user requirements, perform the following activities: ● The overall structure of the system, including system boundaries and interfaces, is illustrated in graphs; ● Provide users with visual interfaces through prototypes, page streams, or other methods, so that users can make their own comments on

consulted data.For some matrices, a small change of an element in the matrix can cause a large error in the final calculation, which is called a pathological matrix. Sometimes incorrect calculation methods can also cause a normal matrix to appear morbid in the operation. In the case of Gaussian elimination, if the elements on the main element are small, they will show morbid characteristics in the calculation.The square value of the ridge regression equation is slightly lower than that of commo

Hope to explore their potential needs from the user's perspective and daily life to guide the design. Participate in the user's life, observe them, to understand the user, to meet their needs. The designer is more need to use "other people's eyes" to treat the things d

From the previous article "Android screen adaptation to the full guide" after writing, often a friend asked me this question: "Can an app only provide a set of graphs to adapt to all the resolution?" "I think it is necessary to write an article to study the problem, so there is this article." Research content Research methods Test environment

Objective Before doing the company's real problem, encounter dynamic planning, there are some problems of mathematical nature more. NetEase 2016 research and development engineers programming problems with the previous topic is very different, not only involved in the two-tree coding, but also related to the breadth of the graph traversal, finally there is a fast row. It can be said that the three topics of gold is very high, so do a summary and
