With more and more businesses building robust and repeatable machine learning pipelines, enhancing business efficiency with AI is no longer merely a research project.

Recommendation systems are some of the most fundamental and useful applications that machine learning can deliver to businesses.

In this blog post I’m going to contrast our previous classifier example with another gradient-boosted tree model, a regression.

Today I’m going to walk you through training a simple classification model.

Establishing a robust pipeline for successful models requires more than a Jupyter notebook and a GPU instance.

Each new observation in the process of black-box optimization assumes there will be infinite possibilities to guess again, typically in multidimensional hyperparameter space.

When it comes to predictive analytics, there are many factors that influence whether your model is performant for the real-world business problem you are trying to address.

Experimenting with data and machine learning can prove useful, but productively collaborating with a team to hand off models from training to production is an entirely different process, and one that can lead to real business transformation.

SigOpt offers the most complete set of advanced experimentation features for model optimization

Metric Strategy enables you to track metrics, set them as constraints, or optimize across multiple at once

When designing models, it’s essential to track as many metrics as you find useful, and ultimately pick one or two to optimize when developing your model.

SigOpt has expanded to include a number of advanced features to help you save time while increasing model performance through experimentation.

When it’s time to ensure that your model, whether that’s a recommendation system, computer vision classifier, or trading strategy is performing as well as it possibly can, you’ll need to choose the right hyperparameter optimization strategy.

Defining, selecting, and optimizing with the right set of metrics is critical to every modeling process, but can be tough to get right.
