QSVM

Quantum support vector machine (QSVM) model. Classifies classical data into two categories. The model is first trained, and fitted. After pre-training, the model predicts the labels of new data points. Methods: Attributes:

​

train

train(
self: ,
train_data: np.ndarray,
train_labels: np.ndarray
) -> None

Trains an SVM model using a custom precomputed kernel from the training data. Parameters:

​

predict

predict(
self: ,
data: np.ndarray
) -> np.ndarray

Predicts labels for new data using a precomputed kernel with a trained SVM model. Evaluates kernel matrix elements which are associated with the support vectors (those associated with non-vanishing coefficients in the prediction equation). Parameters: Returns:

• Type: np.ndarray
• np.ndarray: Predicted labels (0,1).

​

test

test(
self: ,
data: np.ndarray,
data_labels: np.ndarray
) -> tuple[float, np.ndarray]

Predicts the labels of the test dataset and evaluates the resulting test score using the ground-truth labels. Parameters: Returns:

• Type: tuple[float, np.ndarray]
• containing test score (float) and test labels (np.ndarray[int]).

​

get_svm_model

get_svm_model(
self:
) -> SVC

Returns the classical SVM model. Parameters:

​

get_qprog

get_qprog(
self: ,
data_dim: int = 0
) -> QuantumProgram

Returns the quantum program for the kernel at data_dim feature width. Parameters:
