Advanced AI Techniques: Beyond the Basics
Introduction While some techniques are gaining increasing recognition in the broad field of machine learning and are often the first tools in an AI specialist’s toolbox, many powerful methods remain relatively underappreciated. Although these techniques are less well-known, they can significantly improve model performance, reduce training time, and even increase resilience to unexpected challenges. Let’s take a closer look at five of these advanced techniques that promise to take your machine learning projects to new levels.
Transfer learning to smaller networks
When transferring learning with large models (e.g., VGG, ResNet) is widely used, it is effective even in smaller networks, especially when computing resources are limited.
What it does: Transfer learning uses a pre-trained model (a neural network trained on a large data set) as a starting point and then refines it on a smaller, more domain-specific data set. By using smaller networks such as MobileNet, a significant amount of knowledge about the pre-trained model can be retained while reducing the computational effort.
Advantages: Shorter training times and reduced computing resources compared to larger networks. This is advantageous when the data set is small and computing resources are limited.
for hyperparameter optimization
Hyperband is an adaptive resource allocation and early termination strategy that accelerates random search.
What it does: Hyperband is a hyperparameter optimization method that intelligently allocates computing resources. Runs configurations over different time periods to find the best configurations faster than traditional random or grid searches. Benefits of
: Faster convergence to optimal hyperparameters, meaning you can find the best model parameters in less time. Reduces time spent evaluating suboptimal configurations.
