Hyperparameters
Hyperparameters are configuration variables external to the model that are set manually by the user or chosen through an automatic process before the training phase begins. They control the learning process itself, influencing things like how fast a model learns (learning rate), the complexity of a model (number of layers in a neural network), or how often model updates occur. Finding the right set of hyperparameters, often through trial and error or systematic search, is critical for optimal model performance.
Hyperparameters are like the oven temperature, bake time, and ingredients list in a cake recipe, while the cake itself is the trained model; setting them correctly is crucial for edible results.
Incorrectly set hyperparameters can lead to models that don't learn effectively, take too long to train, or perform poorly on new data, directly impacting AI system success.
