 **Many to many**
 
+Recurrent cells can also be used to perform sequence to sequence analysis, also called many to many. Herein, our model takes in multiple inputs of X as a sequence and convert them into outputs. Sequences can be of same size, or different. Machine translation is the most common application of this type.
