Our v1 API has, through its RESTful design, the clarity and structure to facilitate simultaneous optimization loops.
We used SigOpt to tune features and hyperparameters hoping to find a winning combination that could beat the house.
SigOpt can be used to find the location at which a process is maximized.
This post provides a comparison between minimizing the profile likelihood quantity and the kriging variance quantity
Using Gaussian processes and repeated experimentation to expose the optimal behavior for the user.
We show that SigOpt outperforms both strategies scikit-learn recommends for hyperparameter optimization on this task.
Need for approximation stems from costly experimentation. How can we minimize expenditure?
Defining a Gaussian process requires also defining the covariance kernel. Those who use Gaussian processes are aware of the potential for lousy results when using an inappropriate covariance kernel.
SigOpt was used to optimize an Aerodynamics simulation on Rescale. The simulation calculates the best lift ratio for an airfoil across a range of airspeeds and angles of attack.
Our vision is for SigOpt to eliminate that kind of manual testing, and today, we’ve come a step closer.
Boiling all of the key metrics you care about down to a single value is an important process for achieving your goals.
