Если стоимость обучения для вас слишком велика, вы можете подать заявку на финансовую помощь.

• Действительно ли это полностью дистанционный курс? Нужно ли мне посещать какие-либо занятия лично?

  Это полностью дистанционный курс, потому вам не нужно ничего посещать. Все лекции, материалы для самостоятельного изучения и задания доступны всегда и везде по Интернету и с мобильных устройств.

• Получу ли я зачеты в университете за прохождение специализации?

  Эта специализация не приравнивается к зачету в университетах, однако некоторые вузы принимают сертификаты на свое усмотрение. Дополнительную информацию уточняйте в своем деканате.

• What is Natural Language Processing (NLP)?

  Natural language processing is a subfield of linguistics, computer science, and artificial intelligence that uses algorithms to interpret and manipulate human language.

• What is the Natural Language Processing Specialization about?

  In the Natural Language Processing (NLP) Specialization, you will learn how to design NLP applications that perform question-answering and sentiment analysis, create tools to translate languages, summarize text, and even build chatbots. These and other NLP applications will be at the forefront of the coming transformation to an AI-powered future.

  NLP is one of the most broadly applied areas of machine learning and is critical in effectively analyzing massive quantities of unstructured, text-heavy data. As AI continues to expand, so will the demand for professionals skilled at building models that analyze speech and language, uncover contextual patterns, and produce insights from text and audio.

• What will I be able to do after completing the Natural Language Processing Specialization?

  This Specialization will equip you with both the machine learning basics as well as the state-of-the-art deep learning techniques needed to build cutting-edge NLP systems:

  • Use logistic regression, naïve Bayes, and word vectors to implement sentiment analysis, complete analogies, translate words, and use locality-sensitive hashing to approximate nearest neighbors.

  • Use dynamic programming, hidden Markov models, and word embeddings to autocorrect misspelled words, autocomplete partial sentences, and identify part-of-speech tags for words.

  • Use dense and recurrent neural networks, LSTMs, GRUs, and Siamese networks in TensorFlow and Trax to perform advanced sentiment analysis, text generation, named entity recognition, and to identify duplicate questions. 

  • Use encoder-decoder, causal, and self-attention to perform advanced machine translation of complete sentences, text summarization, question-answering, and build chatbots. Learn include T5, BERT, transformer, reformer, and more!

• What makes this Specialization so different?

  The Natural Language Processing Specialization is one-of-a-kind. • It teaches cutting-edge techniques drawn from recent academic papers, some of which were only first published in 2019. • It covers practical methods for handling common NLP use cases (autocorrect, autocomplete), as well as advanced deep learning techniques for chatbots and question-answering. • It starts with the foundations and takes you to a stage where you can build state-of-the-art attention models that allow for parallel computing. • You will not only use packages but also learn how to build these models from scratch. We walk you through all the steps, from data processing to the finished products you can use in your own projects. • You will complete one project every week to make sure you understand the concepts for a total of 16 programming assignments.

• What background knowledge is necessary for the Natural Language Processing Specialization?

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

• Who is this Specialization for?

  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.

• How long does it take to complete the Natural Language Processing Specialization?

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

• Who created the Natural Language Processing Specialization?

  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.

• I’m currently enrolled in one or more courses in the Natural Language Processing Specialization. What does this mean for me?

  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.

• I’ve already completed one or more courses in the Natural Language Processing Specialization but don’t have an active subscription. What does this mean for me?

  • 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.
