Parametri
| scopo | ambito attuale |
|---|
| maniglia | La maniglia di un accumulatore. |
|---|
| localStep | Il valore local_step in corrispondenza del quale è stato calcolato il gradiente sparso. |
|---|
| gradientIndices | Indici del gradiente sparso da accumulare. Deve essere un vettore. |
|---|
| gradientValues | I valori sono le sezioni diverse da zero del gradiente e devono avere la stessa prima dimensione degli indici, ovvero gli nnz rappresentati da indici e valori devono essere coerenti. |
|---|
| gradientShape | Forma del gradiente sparso da accumulare. |
|---|
| haforma conosciuta | Valore booleano che indica se gradient_shape è sconosciuto, nel qual caso l'input viene ignorato durante la convalida. |
