Deep Learning for Everyone

Understanding deep learning and machine learning foundations for data science

Topic: Data
Bruno Gonçalves

Over the past few years we have seen a convergence of two large-scale trends: Big Data and Big Compute. The resulting combination of large amounts of data and abundant CPU (and GPU) cycles has brought to the forefront and highlighted the power of neural network techniques and approaches that were once thought to be too impractical.

Deep Learning, as this new wave of interest has come to be known, has made impressive and unprecedented progress on applications as diverse as Natural Language Processing, Machine Translation, Computer Vision, Robotics, etc. In this lecture, students will learn, in a hands-on way, the theoretical foundations and principal ideas underlying this burgeoning field. The code structure of the implementations provided is meant to closely resemble the way the state of the art deep learning libraries Keras is structured so that by the end of the course, students will be prepared to dive deeper into the deep learning applications of their choice.

What you'll learn-and how you can apply it

  • Linear regression
  • Logistic regression
  • Perceptrons and neurons
  • Back propagation
  • Auto-encoders
  • Training deep networks

This training course is for you because...

  • You are a data scientist who is interested in mastering the concepts and ideas behind neural networks and deep learning.
  • You may have either no previous experience in neural networks or machine learning, and want to take the first grounded steps, or you may have previous experience in using neural network libraries such as Keras or Tensorflow, and wish to get a greater understanding of what’s going on “under the hood.”


Attendees should have experience with: - Basic Python - Numpy - Matplotlib - Jupyter

Course Set-up

  • Scientific Python distribution like Anaconda

About your instructor

  • Bruno Gonçalves is currently a Senior Data Scientist working at the intersection of Data Science and Finance. Previously, he was a Data Science fellow at NYU's Center for Data Science while on leave from a tenured faculty position at Aix-Marseille Université. Since completing his PhD in the Physics of Complex Systems in 2008 he has been pursuing the use of Data Science and Machine Learning to study Human Behavior. Using large datasets from Twitter, Wikipedia, web access logs, and Yahoo! Meme he studied how we can observe both large scale and individual human behavior in an obtrusive and widespread manner. The main applications have been to the study of Computational Linguistics, Information Diffusion, Behavioral Change and Epidemic Spreading. In 2015 he was awarded the Complex Systems Society's 2015 Junior Scientific Award for "outstanding contributions in Complex Systems Science" and in 2018 is was named a Science Fellow of the Institute for Scientific Interchange in Turin, Italy.
