Powering ML-Based Systems With Reliable Data: The Data Annotation Journey

In the last few years, organisations have been increasing their investments in building Machine Learning (ML) based systems. In practice, such systems often took longer than expected to be built or failed to deliver the promised outcome. Data availability and quality have been among the most significant reasons behind this phenomenon. Since each organisation had its custom problems, open datasets or even logged data were not always directly usable. As a result, data collection and annotation processes became more crucial, yet remained under-documented.

How we got on top of our data

Scalability and availability are key aspects of cloud native computing. If your microservice takes five minutes to start up, it becomes very difficult to meet the expectations because adjustments to traffic changes, regional failovers, hot-fixes and rollbacks are simply too slow. In this article, we show how we solved this and a few other problems by taking control of the process of updating our data and storing it in a highly available Redis setup.

Improving Evaluation Practices in Natural Language Generation

Throughout last year I had the opportunity to participate and collaborate on multiple research initiatives in the field of Natural Language Generation (NLG) in addition to my responsibilities as a Data Scientist at trivago. NLG is the process of automatically generating text from either text and/or non-linguistic data inputs. Some NLG applications include chatbots, image captioning, and report generation. These are application areas of high interest internally within trivago as we seek to leverage our rich data environment to enrich the user experience with potential NLG applications.

Improving Your Data Layer with Rebase on Python

Technology keeps getting better and better which, at some point, makes us think "Should I migrate to the latest version/technology or not?" Well when you decide to use a better technology for your application, you have to also consider rewriting the code that your application runs on. The business logic remains the same in most of the cases but the data model would definitely change if you are switching from SQL to some NoSQL Technology for example.
