The Practical Quant wrote a new blog post titled Building a natural language processing library for Apache Spark
[A version of this post appears on the O'Reilly Radar.]The O’Reilly Data Show Podcast: David Talby on a new NLP library for Spark, and why model development starts after a model gets deployed to production.When I first discovered and started using Apache Spark, a majority of the use cases I used it for involved unstructured text. The absence of libraries meant rolling my own NLP utilities, and, in many cases, implementing a machine learning library (this was pre deep learning, and MLlib was much smaller). I’d always wondered why no one bothered to create an NLP library for Spark when many...

[A version of this post appears on the O'Reilly Radar.]A look ahead at the tools and methods for learning from sparse feedback.As more companies begin to experiment with and deploy machine learning in different settings, it’s good to look ahead at what future systems might look like. Today, the typical sequence is to gather data, learn some underlying structure, and deploy an algorithm that systematically captures what you’ve learned. Gathering, preparing, and enriching the right data—particularly training data—is essential and remains a key bottleneck among companies wanting to use machine...

[A version of this appears on the O'Reilly Radar.]A new role focused on creating data products and making data science work in production.by Ben Lorica and Mike LoukidesWe've been talking about data science and data scientists for a decade now. While there’s always been some debate over what “data scientist” means, we've reached the point where many universities, online academies, and bootcamps offer data science programs: master’s degrees, certifications, you name it. The world was a simpler place when we only had statistics. But simplicity isn’t always healthy, and the diversity of data...
