The challenges that epidemics and other global health crises present to the international community are ever changing in each new environment that develops potential risk to the adequate containment and eradication of disease outbreaks. In an effort to find new procedures and practices to limit these risks in 2017 the UN Secretary General’s Global Health Crises Task Force created an independent monitoring and accountability body called the Global Preparedness Monitoring Board (GPMB). In its most recent report produced by the International Federation of the Red Cross and Red Crescent Societies in collaboration with Anthrologica, the GPMB focused on the need…
Deploying Advanced Machine Learning Models at Scale
Novetta is using deep learning to automate advanced analytic pipelines for our customers. These new capabilities identify important pieces of information across large text, image, and video data sets, a challenge faced by many of our Defense and Intelligence Community customers. We developed Argo, a standardized, Docker-based model training and deployment pipeline, to enable rapid evaluation and deployment of state-of-the-art deep learning models. Argo enables models to be deployed as endpoints and, when used with Amazon SageMaker, it forms the foundation for us to deploy, scale, and manage our deep learning models. Simplifying infrastructure setup through Docker and AWS allows…
Ebola in the Democratic Republic of Congo: Novetta Mission Analytics
How data analysis is helping mitigate the second largest outbreak in history.
The ongoing Ebola outbreak in eastern DRC has caused 1,522 deaths, making it the second largest in history. Understanding the causes and expressions of deep-seated local resistance to international response efforts is essential to shortening the outbreak and saving lives. Novetta is providing hands-on analysis via subject matter experts to our partners in the Ebola response community through the classification and analysis of sentiment and voice share in hyper-local and regional media content originating in the North Kivu Ebola hotspot. Novetta’s analysts identify distinct narratives and vectors of propagation from the voices of citizens, civil society stakeholders, Ebola response leadership,…
20% Accuracy Bump in Text Classification with ME-ULMFiT
Introduction In a previous post, we discussed an enhanced method of passing additional data to the ULMFiT1 algorithm for unstructured text classification, which improved accuracy by up to 9%. In follow-on experiments, we have demonstrated that this approach – in which we prepend metadata to the text to provide more information to the model – increased accuracy by up to 20%, in relative terms. This improvement required just a few lines of Python, such that the performance boost comes at essentially no cost. This blog post explains the findings of this more-detailed evaluation, where we have compared how the following…
Introducing Metadata Enhanced ULMFiT
Introduction Since its release in 2018, Novetta’s Machine Learning Center of Excellence has evaluated the performance of Universal Language Model Fine-Tuning (ULMFiT)1 against many customer use cases. We have found that automated labeling of unstructured text helps analysts be more efficient, freeing them up to focus on higher-value tasks. We have been so impressed with its accuracy that we have deployed ULMFiT against a dataset in a production system, with plans to expand it to dozens of other datasets. While ULMFiT’s performance has been impressive on all the datasets we’ve tested, we thought it could do more. Our first use…
State of the Art Text Classification with ULMFiT
Novetta’s Matt Teschke spoke at ODSC East – Boston in the session,”State of the Art Text Classification with ULMFiT” on May 2, 2019. The rise of the internet has led to a faster flow of information, where news posted to a relatively obscure blog can be shared on social media and reach national publications within hours. The volume of information is such that humans alone cannot filter out noise, identify important new viewpoints, and determine how messaging trends are changing over time. At Novetta, we are constantly evaluating advances in deep learning to help our customers…
Novetta has BIG PLANS for AWS re:Invent 2018
Novetta is excited to return to one of the world’s largest tech conferences, AWS re:Invent! This year there are even more ways to engage with us in Las Vegas. For the first time, Novetta will have leaders on stage in two speaking sessions, we are returning to our suite at the Venetian to give customized demos, and we are sponsoring two Worldwide Public Sector (WWPS) events. As in all great partnerships, Novetta and AWS are better together. Novetta’s advanced analytics technology is enhanced by AWS services and we are proud to offer our support, and contribute our expertise and innovation,…

NLP Transfer Learning on SageMaker
Novetta Machine Learning Center of Excellence effort to develop a deep learning model that predicts customer-relevant metadata tags for unstructured text. BACKGROUND: ENRICHMENT OF UNSTRUCTURED TEXT DATA The rise of the internet has led to a faster flow of information, where news posted to a relatively obscure blog can be shared on social media and then reach national publications within hours. The volume is such that humans alone cannot filter out noise, identify important new information, and determine how messaging trends are changing over time. To address this challenge, Novetta Mission Analytics (NMA) helps customers analyze open source and…
