Data Science

The ‘Natural Language Processing (NLP): Deep Learning in Python’ course will teach fundamental concepts of NLP (natural language processing). Students will also learn about the GloVe method, matrix factorization, which is a popular algorithm for recommender systems.

The course covers word2vec, GloVe, word embeddings, and sentiment analysis with recursive nets. This course focuses on how to build and understand API via experimentation. The course is usually available for INR 1,999 on Udemy but students can click on the link and get the ‘Natural Language Processing (NLP): Deep Learning in Python’ for INR 449.

Who all can opt for this course?

  • Anyone who desire to build word vector representations for various NLP applications, including students and pros
  • Modern neural network architectures like recursive neural networks are of interest to professionals and students
  • Should not: Anyone who is unsure about the requirements

Resources Required

  • Install Sci-Kit Learn, Matplotlib, Numpy, Matplotlib, Theano, and TensorFlow (should be extremely easy by now)
  • Being able to independently derive and code the equations requires an understanding of backpropagation and gradient descent
  • Create a recurrent neural network using Theano (or Tensorflowfundamental )’s primitives, especially the scan function
  • Write a Theano feedforward neural network (or Tensorflow)
  • It is advantageous to have knowledge of tree algorithms

Featured Review

Donovan Gonzales (5/5) : This course is good for intermediate deep learning students who are already familiar with a bit of deep learning. The instructor is the best with going into the details and explaining everything piece by piece. Some basics like gradient descent and calculus are required but it’s not too difficult.


  • Henry Chung (5/5) : Awesome tutorial on word embedding (word2vec and glove) techniques with implementations all from scratch.
  • Ayush Agarwal (5/5) : You will get the best of both worlds regarding theory and practice.
  • Jian Zhang (5/5) : The instructor is very experienced with teaching state of the art machine learning in a pedagogical way.
  • Perikumar Javia (5/5) : The developer of the course has perfect directions and pre- requisites in order.


  • Pawe? Luniak (2/5) : Additionaly there are lot of math symbols introduced without explicitly stated what they mean and one have to spend time figuring out what these are.
  • Mariana Maroto (2/5) : They make it really hard for windows users to get data.
  • Felix Mertineit (1/5) : Mister “Lazy Programmer” does not provide insightful answers to questions asked in the forum.
  • Paolo Cabaleiro (2/5) : Examples: – Deep Learning A-Z™: Hands-On Artificial Neural Networks (23 hours) – Python for Data Science and Machine Learning Bootcamp (21.5 hours) Well, I already spent my money here, just don’t like his style.
