Question: Explain how to multiply 250 x 0.25. Multiplying Decimals. Multiplying numbers with decimal has the same principle with multiplying whole numbers. First is to simply multiply them and ignore the decimal points. Then, combined the number of decimal places from the original numbers and plac...
Why is math so heavy in a black hole? How to normalize e^{-5x} in the interval ( 0, infinity ) ? Show all steps with detailed explanation. Explain the angle of repose. Why did it take so long to discover the theory of relativity? Why didn't Newton figure it out?
return(float)(Math.log(numDocs/(double)(docFreq+1))+1.0); } docFreq是根据指定关键字进行检索,检索到的Document的数量,我们测试“北京”词条的docFreq=2104; numDocs是指索引文件中总共的Document的数量,对应explain结果中的maxDocs,我们测试的maxDocs=116302。
For a random forest, the overall feature importance of any feature is given by the mean feature importance for that feature across all the trees \({\mathcal {T}}\). Once again, the feature importances obtained in this way are normalized so as to sum to 1. $$\begin{aligned} fi(f)...

What is the usage of the caret (^) symbol in math? For example, the explanation below uses it multiple times. Explanation: Common denominator = x^2-9x or x(x-9), so that the numerator becomes 3x^2 - Explain why log_a x is defined only for 0 < a < 1 and a > 1. ...
