Enriching Entities In Your Data Lake

Category: Advanced Analytics / Big Data and Entity Analytics / Novetta Nexus Tag(s):  /  /  /  /  /  /  /  /  /

by

Overview Many of our customers have incredible amounts of data scattered across their organization. They know hidden information is locked away, but they need ways to integrate that information and bring it to bear on their missions. One approach to data management is to bring all your data to one place by implementing a data lake – centralizing and storing structured and unstructured information in disparate data sets together. Data lakes drive additional insights into your entire data holdings, enriching the full picture and enabling uncovery of previously unknown links. Storing raw data alongside the results of derived analytics and...

by

Edge compute capabilities are central to many of our customers’ missions, and are only growing in importance. For complex workloads like field forensics or digital media triage, we are seeing an increasing need to use machine learning models to process data where it is being collected. Novetta is pairing our advanced analytics, machine learning, and IoT capabilities with Enveil’s ZeroReveal™ technology through a strategic alliance. Using homomorphic encryption, Enveil’s technology allows sensitive information to be securely processed in unsecure environments, allowing data to be searched or analyzed while it is still encrypted. The data security startup’s core technology was developed...

Deep Learning for Language Identification on Audio Signals

Category: Advanced Analytics / Novetta Nexus Tag(s):  /  /  /  /  /  /  /

by

Introduction Speech-to-text transcription is an important tool for mission analytics and many natural language processing tasks. In most cases, a language is manually preset before speech-to-text transcription can be applied. For scenarios where data is being aggregated in large quantities in various languages, automatic language detection capabilities would greatly streamline data processing. Novetta has developed a technique, Language Identification For Audio Spectrograms (LIFAS), that uses spectrograms of raw audio signals as input to a convolutional neural network (CNN) to be used for language identification. This approach requires minimal pre-processing, as raw audio signals are input into the neural network and...

My Experience With Deep Learning For Coders – Part II

Category: Advanced Analytics / Life At Novetta / Novetta Nexus Tag(s):  /  /  /

by

This Spring, Novetta sponsored a Diversity Fellowship at the University of San Francisco’s Data Institute for the Deep Learning Part II course led by Jeremy Howard and Rachel Thomas, the co-founders of fast.ai. We were happy to support Shawn Tsosie, a veteran who loves deep learning and fast.ai as much as we do. You can hear from him below in his own words describing why he took the course and what he hopes to do with what he learned.   My wife, Claire, had gone into labor with our first child the day this course began. I planned on missing...

by

As a follow up to a very successful re:Invent in 2018, Novetta was invited by AWS to attend a Data Lab in Seattle. This four-day event hosted by AWS gives customers and partners the opportunity to gain hands-on experience with specific AWS services. Amazon coordinators work with AWS product teams to ensure critical engineering, DevOps, and other technical resources are available to support the team. Novetta was invited to the Data Lab to build prototypes with Amazon Neptune, Amazon’s managed distributed graph database service. Novetta was represented by a group of highly skilled data scientists, machine learning researchers, and software...

Navigating Career Choices: Finding the Courage to Make Difficult Decisions

Category: Advanced Analytics / Life At Novetta / Novetta Nexus Tag(s):  /  /  /

by

Career changes are rewarding and terrifying, but like most things in life, there is little reward without risk. Finding the courage to take a chance is hard, but overcoming the fear of change can result in amazing opportunities and remarkable work experience. I began my career in government service with the CIA – completing impactful tours in R&D, applied research, and counterterrorism. I had an awesome job and was on an upwards trajectory supporting a high-impact mission, with a great team and effective management. I was doing something I loved, something I was good at, and making a difference. Ten...

Introducing Metadata Enhanced ULMFiT

Category: Advanced Analytics / Data Analytics / Novetta Nexus / Open Source / Media Analytics Tag(s):  /  /  /  /  /  /  /  /  /  /  /  /

by Matt Teschke, Brian Sacash

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...

Work Mom – And Other Things You Would Never Call a Man

Category: Advanced Analytics / Life At Novetta / Novetta Nexus Tag(s):  /  /  /  /  /

by

I teach a Novetta “Intro to Python” class, and one evening as we were wrapping up, the students and I got into a discussion about my teaching style compared to the other instructor, who was a man. “Will is more matter-of-fact,” a student said, “And your style is more nurturing.” The student meant no harm with his comment, but I took issue with the term nurturing. I associated that word with someone who was soft, a pushover who couldn’t make tough decisions. I think of myself as a technical leader, someone who works to find an answer for every challenge...

Introverts as Leaders

Category: Advanced Analytics / Life At Novetta / Novetta Nexus Tag(s):  /  /  /  /

by

Someone recently asked me how I became a leader, and I honestly didn’t have a good answer. I’m a reluctant leader, at best, so this isn’t a path that I intentionally forged. I had always envisioned leaders as very vivacious, outgoing and commanding of an audience ~ but that’s just not me. I’ve had a few decades to practice the outward roles of being a leader, but when balanced against my preconceptions of how a leader should behave, I’ve always felt like I fell short. It’s taken many years of introspection and affirmation, but I’ve come to realize that my...
