Accessors
py

Methods
__call__()
__call__(
opts):Promise<ArrayLike[][]>
Return the kernel k(X, Y) and optionally its gradient.
Note that this compound kernel returns the results of all simple kernel stacked along an additional axis.
Parameters
| Parameter | Type | Description |
|---|---|---|
opts | object | - |
opts.eval_gradient? | boolean | Determines whether the gradient with respect to the log of the kernel hyperparameter is computed. |
opts.X? | ArrayLike[] | Left argument of the returned kernel k(X, Y) |
opts.Y? | ArrayLike[] | Right argument of the returned kernel k(X, Y). If undefined, k(X, X) is evaluated instead. |
Returns Promise<ArrayLike[][]>
Defined in generated/gaussian_process/kernels/CompoundKernel.ts:102
clone_with_theta()
clone_with_theta(
opts):Promise<any>
Returns a clone of self with given hyperparameters theta.
Parameters
| Parameter | Type | Description |
|---|---|---|
opts | object | - |
opts.theta? | ArrayLike | The hyperparameters |
Returns Promise<any>
Defined in generated/gaussian_process/kernels/CompoundKernel.ts:146
diag()
diag(
opts):Promise<ArrayLike[]>
Returns the diagonal of the kernel k(X, X).
The result of this method is identical to np.diag(self(X)); however, it can be evaluated more efficiently since only the diagonal is evaluated.
Parameters
| Parameter | Type | Description |
|---|---|---|
opts | object | - |
opts.X? | ArrayLike[] | Argument to the kernel. |
Returns Promise<ArrayLike[]>
Defined in generated/gaussian_process/kernels/CompoundKernel.ts:182
dispose()
dispose():
Promise<void>
Disposes of the underlying Python resources.
Once dispose() is called, the instance is no longer usable.
Returns Promise<void>
Defined in generated/gaussian_process/kernels/CompoundKernel.ts:83
init()
init(
py):Promise<void>
Initializes the underlying Python resources.
This instance is not usable until the Promise returned by init() resolves.
Parameters
| Parameter | Type |
|---|---|
py | PythonBridge |
Returns Promise<void>
Defined in generated/gaussian_process/kernels/CompoundKernel.ts:44
is_stationary()
is_stationary(
opts):Promise<any>
Returns whether the kernel is stationary.
Parameters
| Parameter | Type |
|---|---|
opts | object |
Returns Promise<any>
