Defining Loss. Square loss between measurement and target labels.

The Train Loop. Running the hybrid optimizer for 100 epochs.

Final Check. Which component represents the learned 'model' in our circuit?

  • Feature Map
  • Variational Ansatz

Evaluating Performance. Checking accuracy on the test set.

Deployment. Saving your quantum weights for future use.

Graduation. Congratulations on completing the Quantum ML track!

Common Pitfalls & Errors

The Error //

Data Leakage

# Wrong scaler.fit(X) X_train = scaler.transform(X_train) X_test = scaler.transform(X_test) # Correct scaler.fit(X_train) X_train = scaler.transform(X_train) X_test = scaler.transform(X_test)

The Solution //

Never use data from the validation or test sets to train your model. This includes fitting scalers or imputers on the entire dataset before splitting.

The Error //

Overfitting on small datasets

// Solution: Use techniques like Dropout, L2 Regularization, or Early Stopping to prevent the model from overfitting the training data.

The Solution //

Training a complex model (like a deep neural network) on a very small dataset usually leads to memorization instead of generalization. Use simpler models or apply strong regularization.
