how to measure prediction calculating the correlation between a vector and feature when predicting a vector for observation, what is the scoring function of $x$ why would a scoring function be used in estimating the prediction? how to tell whether a prediction is a good one how to measure prediction when predicting a vector the function i,j is why would i use mutual information in predicting how do I measure the accuracy of a prediction can you use mutual information in math how to measure prediction in pointwise mutual information which pointwise function measures the correlation between the pair of features of the predicting vector? which function measures the correlation between the features of the data set? how do you calculate the correlations in a vector what is the pointwise mutual information how to measure correlation of a vector what is mutual information in statistics used for what does mutual information mean in statistics what is the scoring function for prediction in neural network how to determine whether the predicted a vector is good?
