 6. Unlike the recurrent layer, the multi-head attention layer computes the outputs of each inputs in the sequence independently then it allows us to parallelize the computation. But it fails to model the sequential information for a given sequence. That is why you need to incorporate the positional encoding stage into the transformer model.

+## Applications of Transformers
+
+Some of the applications of Transformers include:
+1. Text summarization.
+2. Auto-complete.
+3. NER
+4. Automatic question-answering.
+5. NMT
+6. Chat-bots.
+7. Other NLP tasks:
+    * Sentiment analysis.
+    * Market intelligence.
+    * Text classification.
+    * Charecter recognition.
+    * Spell checking.
