- This talk is an introduction to Natural Language Processing (NLP) and its parent areas of Artificial Intelligence and Linguistics. We will discuss real use cases of NLP in the world today - starting with the core technology, and how that core technology is applied to solving real-world problems. We will focus on the following 3 topics in NLP:
1) Language Models: Used for auto-complete in text, translating from one language to another
2) Part of Speech: Used for keyword extraction, parsing
3) Word Embeddings: Used as a thesaurus, topic identification
Presenter Bio:
Dr. Rutu Mulkar is the founder of Hunchera, and previously the founder of Ticary Solutions (acquired by Sigmoidal). She received her Ph.D. in Natural Language Processing from USC and has contributed to IBM's Watson system that defeated humans in Jeopardy!

This lecture is the best introduction to the NLP that I have been able to find. Thank you, Dr. Mulkur.
The people who are questioning don't seem to have much idea and are really derailing her.
So frustrating, she is killing it and they keep asking nonsense
Thank you for sharing this, it would be very helpful for my project in NLP.
Very Well Structured Lecture and Handled the Questions Well. Good Job. Thanks !
Excellent presentation. Well worth watching. Its unfortunate that she was interrupted with so many poor questions by people who don't seem to have being paying attention.
Thanks, Alex for such kind words. Stay tuned with us for more data science content!
Amazing lecture! Thank you!
I hate to see the interruptions with questions doubting the methods. I admire you posture.
Glad you liked it, stay tuned with us for more resources.
Thank you! I just watched it to have a broad overview about the topic, to better understand the work of our student. Would be nice to have a part II about how to train CBOW and how modern language models like BERT work ...
great talk i was expecting a deeper insights on word embeddings though
Nice job - worth posting a version without the questions
Glad you liked it, Arjun.
Hi, Which will be better for stock prices sentimental analysis

Also discussed with reason plz?
Looking forward to hearing from you soon!!
Great speaker, strange audience. I think she should spend less time asking whether the audience has *more* questions than were already asked, because with every round of questions, they get more low-quality and off-topic ("Does the brain work with probabilities?" 🤡).
Also, 49:55 left me scarred.
How ironic that an expert in the English language hasn't mastered a native English accent (e.g., Western American English).
is that required? also she is an expert in NLP not in English.
NLU can be applied to any language. How many languages do you speak?
Accent is not measurement of intelligence, as we simply can not agree on which accent can be considered as “native”, should it be American, British, Irish, Australian or Newzland accent ?
@@hencychen2484 That's why I said *a* native English accent. She hasn't mastered *any* native accent. If she lived in Australia, I'd at least expect her to try to model her accent after the many Australians she comes into contact with.
@@paulthompson9668 Why would you expect that? Her accent is perfectly comprehensible and doesn't affect your understanding. You might as well say that someone is speaking bad English because they've got a Melbourne accent instead of a Sydney accent and should change accents if they move cities.
