+# Activity Recognition Using Kernel Cross-Correlator (KCC)
+
+This part requires the following WARD 1.0 dataset:
+
+    https://people.eecs.berkeley.edu/~yang/software/WAR/index.html
+
+However, you may also measure the similarity of any signals.
+For example, you may use it as:
+
+	   lambda = 0.1
+	   sigma = 0.2
+	   x = randn(10)
+	   y = randn(10)
+	   z = randn(10)
+
+       correlator = kcc_train(x, lambda, sigma);
+
+       similarity_xy = kcc(y, correlator);
+       similarity_xz = kcc(z, correlator);
+
