Today I saw in this article how to choose the model, feel very good, write here alone.More machine learning combat can read this article: http://www.cnblogs.com/charlesblc/p/6159187.htmlIn addition to the difference between machine learning and data mining,Refer to this arti

Series A card faster. Since I used a card, my mother never had to worry that I could not dig mine.
A-card is particularly suitable for mining by running Bitcoin and digital currency algorithms, the computer generates a specific number and can get 25 bitcoins. The bitcoin algorithm determines that the unit operation time can only generate a fixed number of bitcoi

A bunch of online searches, and finally the links and differences between these concepts are summarized as follows:
1. Data mining: Mining is a very broad concept. It literally means digging up useful information from tons of data. This work bi (business intelligence) can be done, data analysis can be done, even market operations can be done. Using Excel to analyze the data and discover some useful informat

of the current node is the middle half of the distance of all its leaf nodes is float (NUMLEAFS)/2.0/plottree.totalw* 1, but since the start Plottree.xoff assignment is not starting from 0, but the left half of the table, so also need to add half the table distance is 1/2/plottree.totalw*1, then add up is (1.0 + float (numleafs))/2.0/ Plottree.totalw*1, so the offset is determined, then the X position becomes Plottree.xoff + (1.0 + float (numleafs))/2.0/PLOTTREE.TOTALW3, for Plottree function p

What is the difference between data Mining (mining), machine learning (learning), and artificial intelligence (AI)? What is the relationship between data science and business Analytics?
Originally I thought there was no need to explain the problem, in the End data

the VC dimension theory, we need more data to get the same generalization ability.For the second case, there is the same reason. We also inadvertently enlarged the size of the hypothesis set.can refer to Raymond Paul Mapa generalization theory (lesson six)There are two ways to resolve this:1, avoid data snooping. -_-2, can not avoid in the calculation of generalization theory when the data snooping into consideration. For example, consider increasing the complexity of the hypothesis set, increa
