# User Guide

Use this section to prepare data, run decompositions, inspect components, and reconstruct lower-order approximations.

## Main workflow

1. [**Prepare Input Data**](prepare_data)  
   Format tensors, choose a backend, and validate input assumptions.

2. [**Run a Decomposition**](run_a_decomposition)  
   Compute HDMR or EMPR representations through the main workflow.

3. [**Inspect Components**](inspect_components)  
   Examine lower-order terms and interaction structure.

4. [**Reconstruct Data**](reconstruct_data)  
   Build approximations from selected component orders.
