+# while subclassing this works, we should try to detect the length of params
+# and build a new data set for each type of params set...
+# therefore, an instance of SupervisedDataSet could actually be
+# accessed through the params instance...simplified one-to-one mapping
+
+# we are limited to only one classifier per params instance as well
+# however this is sort of a good thing, because built into the params
+# class can be a method that randomizes params, and then evaluates
+
+# we might be able to get this done through multiple inheritance
+# keep all dataset related stuff in a separate class to make it better organized
+
+# we need
+# .evaluate
+# .generate_liked_image
+# .train_from_url_list
+# .reset
