- 1. Trends & Research applications in Natural Language Processing Surya SG (with some vision, robotics, and deep learning)
- 2. About the Course (and its Goals) Research-oriented webinar course! We will understand lots of interesting NLP tasks & some fun novel projects! We’ll start with some basics of NLP. Then cover some specific, latest research topics via several research works. E.g., we will discuss connections of NLP with vision and robotics, and several deep learning for NLP models. No NLP background needed.

How many slices of pizza are there? Is this a vegetarian pizza? What color are her eyes? What is the mustache made of? [Antol et al., 2015]
- 12. What is NLP? Automatic Speech Recognition
- 13. Some Exciting NLP Challenges 1) Human-like Language Understanding: metaphors/idioms, humor, sarcasm, politeness/rudeness 1) Language Generation and Dialogue: document summarization, database to language summary, coherent and intelligent conversation models 1) Grounded Language with Vision and Speech: image-text alignment, language disambiguation via images, image/video captioning, image/video question answering, text to image generation, visual story entailment 1) Embodied Language for Robotic Tasks: instructions for navigation, articulation, manipulation, skill learning 1) Machine Learning Models: deep+structured models, interpretable models, adversarial models, reward-based models (reinforcement learning)
- 14. Human-likeAmbiguousLanguage You: Siri: I am under the weather today. Here is the weather today… 50 F Non-literal: Idioms, Metaphors
- 15. Human-likeAmbiguousLanguage Break a leg! Non-literal: Idioms, Metaphors
- 16. Human-likeAmbiguousLanguage I bet I can stop gambling! Yeah, right! Please do not … Humor, Sarcasm, Politeness/Rudeness
- 17. Human-likeAmbiguousLanguage Clean the dishes in the sink. Prepositional Attachment, Coreference Ambiguities
- 19. Visually Grounded Language Get the mug on the table with black stripes. Text-Image Alignment: Most of our daily communication language points to several objects in the visual world
- 20. Visually Grounded Language Visual Question Answering: Humans asking machines about pictures/videos, e.g., for visually impaired, in remote/ dangerous scenarios, in household service settings Is there milk in the refrigerator?

Computational Linguistics Using computational methods to learn more about how language works Weend up doing this and using it Cognitive Science Figuring out how the human brain works Includes the bits that do language Humans: the only working NLP prototype! Speech Processing Mapping audio signals to text Traditionally separate from NLP, converging? Two components: acoustic models and language models Language models in the domain of stat NLP
- 27. Opportunities andChallenges in Working with Low-Resource Languages Polyglot AI Part - I
- 28. Key Takeaways 1. To build a Polyglot Enterprise-AI we need techniques that address not only the languages of human but also the language of the enterprise 1. You don’t have to solve language of the humans to perfection to begin to address the language of the enterprise. No shame in shooting for the Narrow AI Vs. Broad AI !! 1. Depending on the availability of labeled data, transparency and explain-ability requirements different techniques may have to be applied to build Polyglot Enterprise-AI
