When assessing the reliability of a deep learning model, it is crucial to examine the bias and variance of the model. These two factors can help determine whether the model is underfitting (high bias) or overfitting (high variance).
If a model exhibits high bias, it indicates underfitting. In this case, consider the following strategies:
<ol>
<li>Increase the complexity of the model by using a larger Deep Neural Network (DNN). This can help improve the model's capacity to learn complex patterns in the data.
</li>
<li>Experiment with different types of Artificial Neural Networks (ANNs), as some may be better suited for your specific problem.
</li>
</ol>
On the other hand, if a model displays high variance, it is overfitting. To address this issue, you can:
<ol>
<li>Add more data to the dataset, which can help the model generalize better and reduce overfitting.
</li>
<li>Apply regularization techniques to the model. While this may introduce a slight bias-variance tradeoff, it can help prevent overfitting by constraining the model's complexity.
</li>
</ol>
Keep in mind that the optimal approach will vary depending on the specific situation. Therefore, evaluating the bias and variance of your model should be the first step in determining the most appropriate next steps to improve its performance.
