In the first article of our three-part series, we learned how tuning hyperparameters  helps find the optimal settings for the best results from our machine learning model. Then, in the second article, we learned, and discovered that our tuned model makes more accurate predictions than our untuned model. Depending on the search space, it can […]

Hyperparameter tuning is an essential part of controlling the behavior of a machine learning model. If we don’t correctly tune our hyperparameters, our estimated model parameters produce suboptimal results, as they don’t minimize the loss function. This means our model makes more errors. In practice, key indicators like the accuracy or the confusion matrix will […]

In the first article of this series, we learned what hyperparameter tuning is , its importance, and our various options. In this hands-on article, we’ll explore a practical case to explain how to tune hyperparameters on XGBoost. You just need to know some Python to follow along, and we’ll show you how to easily deploy machine […]

Although IT incidents have always been a concern, the increase in customer-facing technology adds the cost of a bad customer experience to the cost of responding to and remediating an incident. While, in a perfect world, you’d be able to prevent incidents from happening in the first place, the reality is they do happen—more often […]

Security incidents and cyber-attacks cost companies billions each year. Complex, distributed, or microservice-based applications make these incidents challenging to detect. One critical component of operational security is the ability to detect and prevent cyberattacks in running applications. But, building and maintaining secure applications before attacks occur offers even more value. We can develop software that […]

As more devices connect to a network, streaming and processing their generated data becomes a challenge. This challenge becomes acute when we need low-latency querying, aggregation, and stateful computation. The Hazelcast Cloud computation and storage platform supports the in-memory computing that many high-volume Internet of things (IoT) applications require. Hazelcast also provides Jet, enabling Java […]

When someone uses an open-source software component, they automatically enter into an open-source license with the code’s author. Although open-source may seem like a free-for-all, this license is a legally binding contract that declares how and where you can use the code commercially. Usually, an open-source license permits you to freely modify a work and […]

When an incident strikes, the organization’s reputation, revenue, and customer trust are at stake. Assembling an effective incident response team is critical to minimizing the incident’s impact. But what exactly is an incident response team? Who should be a part of the team and what are their responsibilities? Successful incident responses require a team with […]

To build new technology, you need a foundation of existing technology. This is particularly true in software, where many applications rely on third-party libraries. Imagine if we had to build each component of every software product from the ground up. Every developer would need competency in several different areas, and as a result, there would […]

Software developers are in demand — especially in Detroit, the “Silicon Valley of the Midwest.” Despite this, many aspiring developers find themselves employed in other fields, not believing they have the time and money to pursue an education and follow their passion. Rocket Companies®, a Detroit-based organization, designed the 19-week DevBuild boot camp to cultivate […]
