Refactoring in the Frontend: Ideas and Reflections

Refactoring in frontend development is essential for various reasons. Firstly, it enhances the user experience by speeding up user interaction, reducing loading times, and improving accessibility. Modernizing design is another crucial factor as design trends and standards continually evolve. Updating the interface’s appearance can keep the application attractive to users. Additionally, refactoring the visual aspects […]

Deep Learning Models: Monitoring and Re-training

Deep learning has revolutionized numerous fields, from computer vision to natural language processing. However, training and maintaining these models can be challenging. This is where monitoring and evaluations on representative datasets become very important. Why monitor? When a model goes into production it will have previously undergone a thorough evaluation on a data set sufficiently […]

Understanding Machine Learning: A Conceptual Approach

Machine learning is a technique used to create very complex algorithms in an efficient manner. The idea is that by using ML, engineers are able to make algorithmic models that can understand inputs with thousands or millions of interconnected variables and make sense of them to give a coherent output. Although, theoretically, these models could […]

Defining the core accuracy metrics of biometric systems

During the evaluation of Biometrics-based systems, one of the first steps involves defining the core accuracy metrics. This is an important step that helps us to assess if the behavior of our system corresponds with our expectations. Verification scores measure the differences between two given biometrics samples and it’s normally given in 2 forms: a) […]
