The algorithm for identifying the vector field from data.
| Algorithm: Identifying the vector field b(x) from data |
|---|
| Input: Dictionary Ψ(x), data sets X and Y, threshold λ. |
| 1. Compute the matrices G, A, K, L and every vector Bi in equations (12) and (13) for i = 1,…, n. |
2. Calculate  via equation (13). |
| 3. Delete the coefficients smaller than λ and corresponding basis functions in the dictionary. |
| 4. Iterate step 1-3 until no coeffcient is smaller than λ. |
Output: The optimal sparsity solution  and corresponding approximate vector field  for i = 1,…, n. |
