SigOpt's Metric Constraints feature walkthrough: designing an accurate and efficient convolutional neural network.

Scalability is one of the main factors to consider when deciding whether an optimization solution will work for you and your organization.

Defining, selecting, and optimizing with the right set of metrics is critical to every modeling process, but these steps are often hard to execute well.

Defining just the right metrics to assess a model in the context of your business is no easy feat. Metric Constraints helps you establish guardrails for your optimization and experimentation loops.

SigOpt provides customers the opportunity to define uncertainty with their observations and using this knowledge we can balance observed results against their variance to make predictions and identify the true behavior behind the uncertainty.

Gaussian processes are powerful because they allow you to exploit previous observations about a system to make informed, and provably optimal, predictions about unobserved behavior. They do this by defining an expected relationship between all possible situations; this relationship is called the covariance and is the topic of this post.

Rescale gives users the dynamic computational resources to run their simulations and SigOpt provides tools to optimize them. By using Rescale’s platform and SigOpt’s tuning, efficient cloud simulation is easier than ever.
