In short, cross-entropy is exactly the same as the negative log likelihood (these were two concepts that were originally developed independently in the field of computer science and statistics, and they are motivated differently, but it turns out that they compute excactly the same in our classi...

Last, while RSS is easy to compute and interpret, it provides limited insight into the underlying structure of the data. In cases where understanding the relationship between predictors and the response variable is important, there may be better metrics to use. In some ways, RSS can act somewha...
How To Calculate TWR To compute the TWR, you find the rate of return from each chapter and add one to it. Once you have gotten the rate of return for each chapter, multiply them together. Finally, subtract one from that total. By doing so, you are essentially weaving together the ...
