Intermediate Machine Learning with PyTorch
Hands-on analyses of text corpora and images
PyTorch is one of the premier libraries for programming deep neural networks in Python. There is a great deal of subtlety in the design and implementation of effective neural networks. The course walks the student through creating networks for two popular domain areas: text analysis and image classification. We focus both on the general designs of layers and the specific APIs of PyTorch.
What you'll learn-and how you can apply it
- Gain an understanding of general NLP (Natural Language Processing) goals.
- Understand how to apply deep learning techniques to NLP.
- Utilize and customize pre-trained neural network models.
- Customize network layers and examine effects of changes.
This training course is for you because...
You are an aspiring or beginning data scientist.
- You have a comfortable intermediate-level knowledge of Python and a very basic familiarity with statistics and linear algebra. - You are a working programmer or student who is motivated to expand your skills to include machine learning with Python. - You have heard about the enormous promise and power of deep neural networks.
- A first course in Python and/or working experience as a programmer
- College-level basic mathematics
Students should have a system with Jupyter notebooks installed, a recent version of scikit-learn, along with Pandas, NumPy, and matplotlib, and the general scientific Python tool stack. The training materials will be made available as notebooks at a GitHub repository.

About your instructor
David Mertz was most recently a Senior Trainer and Senior Software Developer for Anaconda, Inc., in which role he created and structured its training program. He was a Director of the Python Software Foundation (PSF) for six years and remains co-chair of its Trademarks Committee and of the PSF Scientific Python Working Group. David worked for nine years with D. E. Shaw Research, some folks who built the world's fastest, highly-specialized (down to the ASICs and network layer) supercomputer for performing molecular dynamics.
David wrote the widely read columns Charming Python and XML Matters for IBM developerWorks, short books for O'Reilly, and the Addison-Wesley book Text Processing in Python. He has spoken at multiple OSCons, PyCons, and AnacondaCon, and was invited to be a keynote speaker at PyCon-India, PyCon-UK, PyCon-ZA, PyCon Belarus, PyCon Cuba, and PyData SF.
David is pleased to find Python becoming the default high-level language for most scientific computing projects.
