+<div class="block">Calculate conditional entropy H(Y|X) of random variables X and Y following conditional entropy's
+ <a href="http://en.wikipedia.org/wiki/Conditional_entropy" target="_blank">wiki definition</a>,
+ X is the conditional variable and Y is the variable that conditions on X.
+
+ <p>
+ Each tuple of the input bag has 2 fields, the 1st field is an object instance of variable X and
+ the 2nd field is an object instance of variable Y. An exception will be thrown if the number of fields is not 2.
+ </p>
+
+ <p>
+ This UDF's constructor definition and parameters are the same as that of <a href="../../../../datafu/pig/stats/entropy/Entropy.html" title="class in datafu.pig.stats.entropy"><code>Entropy</code></a>
+ </p>
+
+ Note:
+ <ul>
+ <li>The input bag to this UDF must be <b>sorted</b> on X and Y, with X in the first sort order.
+ An exception will be thrown if the input bag is not sorted.
+ <li>The returned entropy value is of double type.
+ </ul>
+
+ <p>
+ How to use:
+ </p>
+
+ <p>
+ This UDF calculates conditional entropy given raw data tuples of X and Y without the need to pre-compute per tuple occurrence frequency.
+ </p>
+
+ <p>
+ It could be used in a nested FOREACH after a GROUP BY, in which we sort the inner bag and use the sorted bag as this UDF's input.
+ </p>
+
+ Example:
+ <pre>
+ <code>--define empirical conditional entropy with Euler's number as the logarithm base
+ define CondEntropy datafu.pig.stats.entropy.CondEntropy();
+
+ input = LOAD 'input' AS (grp: chararray, valX: double, valY: double);
+
+ -- calculate conditional entropy H(Y|X) in each group
+ input_group_g = GROUP input BY grp;
+ entropy_group = FOREACH input_group_g {
+ input_val = input.(valX, valY)
+ input_ordered = ORDER input_val BY $0, $1;
+ GENERATE FLATTEN(group) AS group, CondEntropy(input_ordered) AS cond_entropy;
+ }
+ </code>
+ </pre>
+
+ Use case to calculate mutual information:
+ <pre>
+ <code>------------
+ -- calculate mutual information I(X, Y) using conditional entropy UDF and entropy UDF
+ -- I(X, Y) = H(Y) - H(Y|X)
+ ------------
+
+ define CondEntropy datafu.pig.stats.entropy.CondEntropy();
+ define Entropy datafu.pig.stats.entropy.Entropy();
+
+ input = LOAD 'input' AS (grp: chararray, valX: double, valY: double);
+
+ -- calculate the I(X,Y) in each group
+ input_group_g = GROUP input BY grp;
+ mutual_information = FOREACH input_group_g {
+ input_val_x_y = input.(valX, valY);
+ input_val_x_y_ordered = ORDER input_val_x_y BY $0,$1;
+ input_val_y = input.valY;
+ input_val_y_ordered = ORDER input_val_y BY $0;
+ cond_h_x_y = CondEntropy(input_val_x_y_ordered);
+ h_y = Entropy(input_val_y_ordered);
+ GENERATE FLATTEN(group), h_y - cond_h_x_y;
+ }
