What are the model interpretation techniques in Torch?

Explanation techniques in Torch include:

1. Gradient computation: By calculating the gradients of the model output with respect to the inputs, we can determine the degree of influence of each input on the model output.
2. Saliency Maps are generated based on gradient calculations to show which parts of the input have the greatest impact on the model’s output.
3. Integrated Gradients: This approach measures the contribution of each input feature to the model output by interpolating between the input and a baseline input and calculating the gradient.
4. LIME: By generating a series of perturbations to the inputs and observing how the model output changes, we can estimate the sensitivity of the model to each input feature.
5. SHAP: This method calculates the contribution of each input feature to the model output by taking a weighted average of the permutations and combinations of each input feature.

These model interpretation techniques can help us understand how models make predictions, thus improving their interpretability and reliability.
