Solving data science problems with Record Matching

Presentation by Data Science alum Jordan McIver ’15

presentation

Every organisation needs to be able to properly connect disparate datasets to take full advantage of their data assets. Alchemmy held an event to discuss approaches and technologies to connect datasets and watchouts to consider once they are connected.

Check out my talk here where we look at an approach that best enables data scientists by partnering them with the other staff who actually hold the context of the data:

Video summary

Most businesses have some or all of the following problems: not enough data science resources for the work required; a large community of data-adjacent staff who have most of the context but are not contributing what they know in the right way; data science problems lacking that same context; algorithms that cannot overcome a lack of data quality or availability of training data. Jordan walks through the use of interactive dashboards where users quality assess the data and this feeds back into the data science process which addresses these problems.

Last November I was given the unique opportunity to present my ideas to an audience that usually doesn’t get to hear much about the inner workings of the financial system and central banking. At the TEDx Conference “Spectrum” in Gothenburg, Sweden, I was one of 10 speakers who were given not more than 20 minutes to convey an “idea worth spreading.”

My talk centered around how money is created in a modern economy and what can be done to improve upon this process, in particular in the context of the euro crisis. Quite a challenge, as it turned out, given the short amount of time and the need to keep things understandable and entertaining since most of the audience did not have an economic background.

It was, however, an extremely exciting and rewarding experience.

After getting in touch with the organizers through a chance encounter at the Annual Meeting of the Asian Development Bank (ADB) last year, all speakers got an individually assigned coach who provided excellent feedback and recommendations for the talk.

The day of the conference itself was thoroughly enjoyable (at least after the initial rush of adrenaline had subsided). It was fascinating to interact with people from widely varying backgrounds that all shared a natural curiosity and desire to learn from each other. And at the end of the day it felt great for having been able to contribute to this, by providing people with insight into a topic so important, yet so little-known.
