Understanding Underfitting
Underfitting occurs when a model lacks the capacity or flexibility
to represent the complexity of the underlying data. This often
happens when the model is too simple or when the training data is
insufficient or noisy. As a result, the model fails to capture the
true relationship between the input features and the target
variable, leading to high bias and low variance.
Causes of Underfitting:
-
Model Complexity: Choosing a simple model with
too few parameters or features can result in underfitting as it
may not be able to capture the complexity of the data.
-
Insufficient Training Data: If the training
dataset is small or not representative of the true data
distribution, the model may underfit as it lacks enough
information to learn meaningful patterns.
-
Over-regularization: Excessive use of
regularization techniques, such as L1 or L2 regularization, can
lead to underfitting by penalizing model complexity too heavily,
resulting in overly simplified models.
Detecting Underfitting:
-
Poor Performance: A clear sign of underfitting
is when the model performs poorly on both the training and
validation datasets, indicating that it fails to capture the
underlying patterns in the data.
-
High Bias: Models suffering from underfitting
typically have high bias and low variance, meaning they make
simplistic assumptions about the data and perform consistently
poorly across different datasets.
Addressing Underfitting:
-
Increase Model Complexity: Choose a more
complex model architecture with a greater number of parameters
or features to increase the model's capacity to capture the
underlying patterns in the data.
-
Feature Engineering: Introduce additional
relevant features or transform existing features to provide the
model with more information to learn from and improve its
predictive performance.
-
Reduce Regularization: Relax the regularization
constraints or fine-tune the regularization parameters to allow
the model to learn more complex relationships in the data
without being overly penalized.
