 ## Limitations
 The model has limited training data of trash in the environment. Additionally, the model overrepresents plastic and glass
 in its predictions due to sampling bias and visual similarities between plastic, glass, and other common types of trash. 
-Additionally, may types of trash look visually similar or identical, even to humans.
+
+One concern is that many types of trash look visually similar or identical, even to humans. The model can get confused and rank these classes at similar probabilities.
 As a solution, the model is marked as 'correct' when the correct label is within the model's top r most predicted trash types. 
 
-r = 3 gives the most appropriate results.
+radius = r = 3 gives the most appropriate results.
