Overview of this book

Data Analysis with Python offers a modern approach to data analysis so that you can work with the latest and most powerful Python tools, AI techniques, and open source libraries. Industry expert David Taieb shows you how to bridge data science with the power of programming and algorithms in Python. You'll be working with complex algorithms, and cutting-edge AI in your data analysis. Learn how to analyze data with hands-on examples using Python-based tools and Jupyter Notebook. You'll find the right balance of theory and practice, with extensive code files that you can integrate right into your own data projects. Explore the power of this approach to data analysis by then working with it across key industry case studies. Four fascinating and full projects connect you to the most critical data analysis challenges you’re likely to meet in today. The first of these is an image recognition application with TensorFlow – embracing the importance today of AI in your data analysis. The second industry project analyses social media trends, exploring big data issues and AI approaches to natural language processing. The third case study is a financial portfolio analysis application that engages you with time series analysis - pivotal to many data science applications today. The fourth industry use case dives you into graph algorithms and the power of programming in modern data science. You'll wrap up with a thoughtful look at the future of data science and how it will harness the power of algorithms and artificial intelligence.

Architecture for operationalizing data science analytics

In the previous section, we saw how PixieApps combined with the PixieDust display framework offer an easy way to build powerful dashboards that connect directly with your data analytics, allowing for rapid iterations between the algorithms and the user interface. This is great for rapid prototyping, but Notebooks are not suitable to be used in a production environment where the target persona is the line of business user. One obvious solution would be to rewrite the PixieApp using a traditional three tiers web application architecture, for example, as follows:

React (https://reactjs.org) for the presentation layer
Node.js for the web layer
A data access library targeted at the web analytics layer for machine learning scoring or running any other analytic jobs

However, this would provide only a marginal improvement over the existing process, which would consist only, in this case, of the ability to do iterative implementation with the PixieApp...
