Rasa Developer Summit - William Galindez Ariaz, Octesoft - Dial Rasa for Dinner

How does a Colombian living in Prague learn a notoriously difficult language? While going beyond dry lessons and into actually understanding how to hold conversations? This session discusses how a Czech speaking Rasa bot can simulate scenarios that can spar learners to help in different situations - and different languages.

WHAT YOU'LL LEARN
Rasa NLU allows you to explore markets with 'exotic languages' such as Czech
The bot created with Rasa is currently helping me to learn a new language and prepare myself for real case situations, such as ordering food in a foreign country
Being knowledgeable in LUIS, Watson and Rasa, I can recommend the pure ML approach of Rasa to fire up a bot (without going through tedious Dialog management)
Rasa is the technology, we dream the use cases, in my experience, my Waiter bot has a real impact in my life, what is your Idea?

William Galindez Arias is an Electronic Engineer, from Colombia, who moved to Prague to study Data Science. William works as Machine Learning Consultant for Fortune 500 companies, helping them find use cases for them to apply AI.
