Introduction
Google “NLP jobs” and a remarkable number of relevant searches appear. There are companies emerging all over the world that deal exclusively with natural language processing roles! (PNL)! Industry Demand for NLP Experts Has Never Been Higher, and is expected to increase exponentially in the coming years.
But the supply side is falling short. Newbies and even experienced people who want to land a position based on NLP are struggling to break into the industry.. We can point out one of the areas of greatest pain: lack of structured learning.
There are too many resources these days that cover the concepts of NLP., but most of them do it sparsely. Newcomers tend to read articles and books, analyze various blogs and videos, and end up struggling to rebuild an understanding from one extreme to the other.
This is where our NLP learning path comes in!! We are delighted to present a comprehensive and structured learning path to help you learn and master NLP from scratch at 2020!
This learning path has been selected by DataPeaker experts who have gone through hundreds of resources to select it for our community. Follow this path in 2020 and soon you will be about to get a position in the domain of NLP!
Our framework for the NLP learning path
Structure: is the core of everything we do. Our learning routes are popular both for their structure and for their comprehensive nature. Here's how we've broken down each month of the NLP learning path to help you plan your learning journey.:
- Target: What will you learn in that month? What are the key findings? How will your journey to NLP progress? We mention this at the beginning of each month to make sure you know where you are and where you will be at the end of that particular month..
- Suggested time: How much time on average should you spend on that section per week
- Resources to learn: A collection of top resources for the NLP topics you will learn in that month. This includes articles, tutorials, videos, research papers and other similar resources.
