+<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;
+ }

+<div class="block">Calculate the empirical entropy of random variable X given its occurrence frequencies, following entropy's
+ <a href="http://en.wikipedia.org/wiki/Entropy_%28information_theory%29" target="_blank">wiki definition</a>.
+
+ <p>
+ This UDF's constructor takes 1 argument: the logarithm base, whose definition is the same as that defined in <a href="../../../../datafu/pig/stats/entropy/Entropy.html" title="class in datafu.pig.stats.entropy"><code>Entropy</code></a>
+ </p>
+
+ Note:
+ <ul>
+ <li>Unlike <a href="../../../../datafu/pig/stats/entropy/Entropy.html" title="class in datafu.pig.stats.entropy"><code>Entropy</code></a>, which calculates entropy from sorted raw data bag in accumulative mode,
+ this UDF calculates entropy from the data's occurrence frequencies which does not need to be sorted, either in accumulative or algebraic mode.</li>
+ <li>Each tuple of the UDF's input bag <b>must only</b> have 1 field, the occurrence frequency of a data instance,
+ and the data type of this field <b>must</b> be int or long. Otherwise, an exception will be thrown.</li>
+ <li>Negative frequency number will be silently discarded and a warning message will be logged in the job's log file.</li>
+ <li>The returned entropy value is of double type.</li>
+ </ul>
+
+ <p>
+ How to use:
+ </p>
+
+ <p>
+ To use this UDF, customer needs to pre-compute the occurrence frequency of each data instance, often in an outer GROUP BY
+ , and then use this UDF to calculate entropy with those frequency numbers in another outer GROUP BY.
+ </p>
+
+ <p>
+ Compared with <a href="../../../../datafu/pig/stats/entropy/Entropy.html" title="class in datafu.pig.stats.entropy"><code>Entropy</code></a>, this UDF is more scalable when we need to handle a very large data set,
+ since it could distribute computation onto mappers and take advantage of combiners to reduce intermedidate output from mappers to reducers.
+ </p>
+
+ Example:
+ <pre>
+ <code>define Entropy datafu.pig.stats.entropy.EmpiricalCountEntropy();
+
+ input = LOAD 'input' AS (val: double);
+
+ -- calculate the occurrence of each instance
+ counts_g = GROUP input BY val;
+ counts = FOREACh counts_g GENERATE COUNT(input) AS cnt;
+
+ -- calculate entropy
+ input_counts_g = GROUP counts ALL;
+ entropy = FOREACH input_counts_g GENERATE Entropy(counts) AS entropy;
+ </code>
+ </pre>
+
+ Use case to calculate mutual information using EmpiricalCountEntropy:
+
+ <pre>
+ <code>define Entropy datafu.pig.stats.entropy.EmpiricalCountEntropy();
+
+ input = LOAD 'input' AS (valX: double, valY: double);
+
+ ------------
+ -- calculate mutual information I(X, Y) using entropy
+ -- I(X, Y) = H(X) + H(Y) - H(X, Y)
+ ------------
+
+ input_x_y_g = GROUP input BY (valX, valY);
+ input_x_y_cnt = FOREACH input_x_y_g GENERATE flatten(group) as (valX, valY), COUNT(input) AS cnt;
+
+ input_x_g = GROUP input_x_y_cnt BY valX;
+ input_x_cnt = FOREACH input_x_g GENERATE flatten(group) as valX, SUM(input_x_y_cnt.cnt) AS cnt;
+
+ input_y_g = GROUP input_x_y_cnt BY valY;
+ input_y_cnt = FOREACH input_y_g GENERATE flatten(group) as valY, SUM(input_x_y_cnt.cnt) AS cnt;
+
+ input_x_y_entropy_g = GROUP input_x_y_cnt ALL;
+ input_x_y_entropy = FOREACH input_x_y_entropy_g {
+ input_x_y_entropy_cnt = input_x_y_cnt.cnt;
+ GENERATE Entropy(input_x_y_entropy_cnt) AS x_y_entropy;
+ }
+
+ input_x_entropy_g = GROUP input_x_cnt ALL;
+ input_x_entropy = FOREACH input_x_entropy_g {
+ input_x_entropy_cnt = input_x_cnt.cnt;
+ GENERATE Entropy(input_x_entropy_cnt) AS x_entropy;
+ }
+
+ input_y_entropy_g = GROUP input_y_cnt ALL;
+ input_y_entropy = FOREACH input_y_entropy_g {
+ input_y_entropy_cnt = input_y_cnt.cnt;
+ GENERATE Entropy(input_y_entropy_cnt) AS y_entropy;
+ }
+
+ input_mi_cross = CROSS input_x_y_entropy, input_x_entropy, input_y_entropy;
+ input_mi = FOREACH input_mi_cross GENERATE (input_x_entropy::x_entropy +
