AWS Certified AI Practitioner AIF-C01 Practice Question
Within the context of machine learning, what does the term "bias" most accurately describe when evaluating a model's predictions against real-world outcomes?
A consistent error introduced by algorithmic assumptions or training data that favors certain outcomes in the model's predictions.
Random fluctuations in predictions that arise solely from noisy data samples.
The total number of trainable parameters present in a specific neural network layer.
The iterative procedure of adjusting model weights during backpropagation.
Bias is the systematic error that causes a model's predictions to be consistently skewed toward certain values or groups. This usually stems from assumptions within the algorithm or from imbalanced or representative issues in the training data. Random noise is variance, not bias. The count of parameters merely reflects model size, and weight updates during backpropagation describe the learning process, not bias itself.
