In-Class Speaker Series: iPython & pymetrics

By Emily Wilson • October 22, 2015

'The industry has really woken up to the value of data,' said Brian Granger, core developer of the iPython project and Associate Professor of Physics at Cal Poly State University, San Luis Obispo. He spoke to the Metis cohort last week, and though he was scheduled for one hour, the conversation extended well beyond 60 minutes as the students asked question after question about his influential open source work.

He has a team of full-time developers working with him on the iPython Notebook, 'an interactive computational environment, in which you can combine code execution, rich text, mathematics, plots and rich media.'

Granger went into detail about the Notebook's development, evolution, and functionality, and also spoke on a broader scale about the data science field and its rapid growth. Traditionally, innovations and developments in the data science field have originated as student projects within academia. As the wider business community begins to realize the potential power of data, academia and industry are mixing in interesting but often 'challenging ways,' according to Granger.

One important way to tackle the present challenges is to focus on narratives within data -- something the Notebook does well. Successful data scientists need to be able to create and tell moving, relatable stories from within the data.

"The big idea that makes the [iPython] notebook important isn't just about the code and data, it's also about the narrative around that," he said.

Narrative is also important to career search platform pymetrics. It helps users tell their career stories through a combination of big data, neuroscience, and machine learning, recommending career paths to job seekers and helping companies hire more effectively.

Alena Chiang, pymetric's Head of User Acquisition, also spoke with the Metis cohort last week about the platform, saying that finding a job doesn't have to be the "painful process" it often is.

Founded by two neuroscientists, pymetrics assesses cognitive and personality traits through a series of online games. Anyone can sign on, make a profile, and play the games, which analyze 50+ cognitive-emotional traits in a short period of time. Data science is then used to profile each user and the platform helps match users and companies.

Chiang highlighted the important role that data and data scientists play in making pymetrics a successful tool for all involved.

This week, we've had two speakers already and have one more planned for this evening, as our in-class speaker series continues:

Dean Malmgren, Co-founder, Datascope Analytics



Lambert Hogenhout, Chief Data Scientist, The United Nations



Brad Groff, Senior Manager, Data Science Capital One labs

6 Things to Know About the Metis Seattle Data Science Bootcamp

By Emily Wilson • October 24, 2018

Seattle is the fastest-growing big city in the United States and it’s also become the second strongest tech market in the country. Along with major players like Amazon and Microsoft, there’s a significant mid-sized and startup community feeding into the city’s contagious energy – and many of these companies need data scientists! To help fill those roles, we opened our Seattle campus in September 2017 with the plan to harness and guide some of the city’s tech talent toward data science specifically. Here are 6 things you should know about our bootcamp in Seattle.
