3. IDEA
“Chat bots aim to make life simpler for its users. Learning
from user behaviour & preferences, chat bots should be
capable of understanding your needs.“
“Imagine ordering pizza, booking a cab, getting flight
status, reading news, getting stock updates, all within
just one platform? It can save so much space on your
mobile phone, simple UI on a messaging platform which
you already like (one platform, many services).”
4. WHY NOW
• Natural: humans always liked interaction that is:
1) instant; 2) natural.
18. RETRIEVAL-BASED MODEL
• Use a repository of predefined responses to pick
an appropriate response based on the input and
context.
• These systems don’t generate any new text, they
just pick a response from a fixed set
19. GENERATIVE MODEL
• Don’t rely on pre-defined responses. They
generate new responses from scratch
• Based on Machine Translation techniques

22. A TAXONOMY OF MODELS
• Retrieval-based models (easier) vs Generative
models (harder)
• Short-Text Conversations (easier) vs long
conversations (harder)
• Open domain (harder) vs closed domain (easier)
