Target / outcome is knownI know how to classify this data, I just
need you(the classifier) to do it.
Target / outcome is unknownI have no idea how to classify this data,
can you(the algorithm) create a classifier for me?
ReinforcementVS
Classification & outcome is unknownI have no idea how to classify this data, can you classify this data and I'll give you a reward if it's
correct or I'll punish you if it's not.
machine learning, the basics

Two sides to the data story
Declared
Observed
ContentStructured, explicit, self-declared, and static
ContextUnstructured, time-series,
observed, and dynamic
![Page 9: Filip Maertens - AI, Machine Learning and Chatbots: Think AI-first](https://reader034.vdocument.in/reader034/viewer/2022052216/5a668c947f8b9ad4438b4939/html5/thumbnails/9.jpg)
“ don’t worry. we have lots of data! “
Data can be unlabeled
Data usually is dirty
Data is sometimes not
relevant
Over 80% of data is not, wrong or insufficiently
labeled
Resolutions, sampling rates,
special characters, hidden values, NULL values, …
Sometimes the data is simply not
fit for purpose!
I don’t need a lot of data. I need good data.

“ … but I also need enough data! “
UNDERFITTINGUsing an algorithm that cannot capture the full complexity of the data
![Page 11: Filip Maertens - AI, Machine Learning and Chatbots: Think AI-first](https://reader034.vdocument.in/reader034/viewer/2022052216/5a668c947f8b9ad4438b4939/html5/thumbnails/11.jpg)
“ … and data should also be diverse enough! “
OVERFITTINGTuning the algorithm so carefully it starts matching the noise in the training data
![Page 12: Filip Maertens - AI, Machine Learning and Chatbots: Think AI-first](https://reader034.vdocument.in/reader034/viewer/2022052216/5a668c947f8b9ad4438b4939/html5/thumbnails/12.jpg)

Difficult to ignore the conversational opportunityWith billions of users exchanging messages and interacting with each other over messaging platforms, a business can no longer ignore the potential and opportunity of getting hands-on with “chat bots”.

Over 90% understandingTechnology maturity
New and improved methods for natural language understanding have produced unprecedented levels of accuracy in understanding and dealing with natural language.
Channel maturity
With over 1 billion users, exchanging over 60 billion messages per day on Facebook and WhatsApp, and spending over 1 hour per day on messaging platforms,
Over 60 billion messages / day

A brief history of conversational agents
Personal assistants, virtual agents, chat bots or conversational agents. However you want to call this technology, they all hint for the need for humans to interact with machines in a more natural and frictionless manner when dealing with complex interactions.

Building the frictionlesscustomer experience
A seamless user experience between machine and human is the general objective for any company that is using technology to scale their business or deliver a competitive service to their constituents.
While mobile has trumped web in terms of usability by using tactile interfaces, conversational interfaces might trump mobile by using natural language.
