Working knowledge of machine learning, intermediate Python experience including DL frameworks & proficiency in calculus, linear algebra, & stats.

This Specialization is for students of machine learning or artificial intelligence and software engineers looking for a deeper understanding of how NLP models work and how to apply them.

This Specialization consists of four Courses. At the rate of 5 hours a week, it typically takes 4 weeks to complete each Course.

Younes Bensouda Mourri and Lukasz Kaiser created the Natural Language Processing Specialization.

Younes Bensouda Mourricompleted his Bachelor's in Applied Math and CS and Master's in Statistics from Stanford University. Younes helped create 3 AI courses at Stanford - Applied Machine Learning, Deep Learning, and Teaching AI - and taught two for a few years. Currently, he is an adjunct lecturer of computer science at Stanford University.

Lukasz Kaiser is a Staff Research Scientist at Google Brain and the co-author of Tensorflow, the Tensor2Tensor and Trax libraries, and the “Attention is all you need” Transformer paper.

If you would like to update to the new material, reset your deadlines. If you’re in the middle of a course, you will lose your progress when you reset your deadlines. Please save any notebook assignments you've submitted by downloading your existing notebooks before switching to the new version.

• Your certificates will carry over for any courses you’ve already completed. 

• If your subscription is currently active, you can access the updated labs and submit assignments without paying for the month again. 

• If you go to the Specialization, you will see the original version of the lecture videos and assignments. You can complete the original version if so desired (this is not recommended).

• If you would like to update to the new material, reset your deadlines. If you’re in the middle of a course, you will lose your notebook work when you reset your deadlines.• Please save your work by downloading your existing notebooks before switching to the new version. 

• If you do not see the option to reset deadlines, contact Coursera via the Learner Help Center.

• Your certificates will carry over for any courses you’ve already completed. • If your subscription is currently inactive, you will need to pay again to access the labs and submit assignments for those courses.

This course is completely online, so there’s no need to show up to a classroom in person. You can access your lectures, readings and assignments anytime and anywhere via the web or your mobile device.
