at all times. Based on this statistic, you'll see which upgrades are selling better and are more popular with players. Further down, you can also find out if a user is only involved in a certain type of micro-transaction and make adjustments (if necessary) to the game based on this.Finally, I hope the above list of indicators will help game developers to better study game performance. Keep in mind that specific indicators may only be available for specific games, and you need to select the corr

meticulous processing, such as the number of data types to fill in the number, but in this task does not affect the nature of the class feature do Labelencode Many of the features in real-world data are not numeric types, but category types, such as red/blue/white, although decision trees are naturally adept at dealing with the characteristics of category types, but we still need to convert the original st

This is a paper I have spent a month in my postgraduate studies. It takes only a month to design and write a paper. It can be more than just a few minutes to publish, add, modify, and wait for the paper to be published, I remember writing started in November 2010. I wrote it in December 2010. I made a draft at the end of 2010. I changed it several times in early 2011 and finally published it in May. In November 2010, my tutor said that there were many topics that could be studied on wireless se

The first example we look at in the drafting process, we need a formula: $p ={12\over q}$, then we observe the effect. And then another one that uses \ (to do the inline \ (p={12\over q}\) Latex formula for the delimiterIn the following example, we have a large section of mathematical formulas, and we have another line to show:$$|\vec{a}|=\sqrt{a_x^2 + a_y^2 + a_z^2}.$$These two models are basically enough, and the specific Latex syntax must be self-GoogleUsing Latex to edit paper-level

This article from: http://news.cnblogs.com/n/92343/ I have previously recommended C/C ++ courses for MIT. Today I saw a group of free open courses on computer science and programming on their website (YouTube video ), after reading a few courses, I thought it was very systematic, and I felt like 1.1 million users. Although it is a theoretical course, we can feel that there is still a big gap in educ
