In the last decade, deep learning has become a popular and effective technique for learning on a variety of different data types. While most people know of applications of deep learning to images or text, deep learning can also be useful for a variety of tasks on audio data!
At my previous job working on self driving cars, I spent a lot of time working on deep learning models for imagery and 3D pointclouds. While we had some cool applications of audio processing, I only dabbled in it and never seriously worked on it.
However, here at Aquarium, we have…
Machine learning on unstructured data (like images or audio) is much harder than machine learning on structured data. Fortunately, deep neural networks can produce structured representations known as “embeddings” that are remarkably effective in organizing and wrangling large sets of unstructured data.
At Aquarium, we heavily utilize embeddings to make it easier for our users to work with unstructured data. In this article, we’re going to explore why these embeddings are so effective and how to use these embeddings to speed up common ML workflows.
Whenever an ML team discusses what they should do to improve their models, there’s inevitably a point at which someone throws up their hands and says, “Well hey, let’s just get more data and retrain the model. Maybe that will help.”
There’s some promise to this idea. Holding the model code fixed and iterating on data can be the most effective way to improve your models. Randomly sampling data to retrain on yields great improvements up to a certain point. But after that point, you start to get less and less improvement to model performance as you add more data.
This is the second part of our series on scaling ML teams! Read on if you’re a leader in an ML team that is starting to grow beyond 10 people and scale from one team to a collection of teams working on the ML pipeline. If you’re a smaller team or you haven’t seen our first post on scaling from 0–10 people, you may want to read that first.
It’s been a frantic few years. The ML pipelines have become more mature, more models have been deployed in new areas, and total ML-related headcount has grown quite a lot. What…
So you’re doing an ML project! Maybe you want to build an object detection system for a robotics application or you want to add a recommender system to your webapp.
You’ll need a team to build and improve this ML system. In the beginning, this can be a single (very stressed) engineer hacking together an MVP, but it can evolve into an entire department with highly specialized teams and hundreds of people. At each stage of developing a model pipeline, you will encounter different problems that require different team structures to overcome.
Leaders (Engineering Managers, Tech Leads, Product Managers, etc.)…
Let’s say you’re training a machine learning model to solve a problem. You’ve just gotten something working. Maybe you used a model from scikit-learn or tensorflow/models, but now it’s at 80% accuracy and you want to make it better. What do you do?
You may be tempted to try some clever feature engineering. Perhaps using Yolo v7 would be better than the Yolo v3 you’re using now. Or hey, maybe you should try that new optimizer (NAdamGradProp with momentum) you saw on arxiv-sanity last week.
Hold your horses. Before you try anything, figure out what the problem is and then…
