Within Session P300 with Learning Curve#
This example shows how to perform a within session analysis while also creating learning curves for a P300 dataset. Additionally, we will evaluate external code. Make sure to have tdlda installed , which can be found in requirements_external.txt
We will compare three pipelines :
Riemannian geometry
Jumping Means-based Linear Discriminant Analysis
Time-Decoupled Linear Discriminant Analysis
We will use the P300 paradigm, which uses the AUC as metric.

Evaluation#
We define the paradigm (P300) and use the BNCI 2014-009 dataset for it. The evaluation will return a dataframe containing AUCs for each permutation and dataset size.
paradigm = P300(resample=processing_sampling_rate)
dataset = BNCI2014_009()

dataset.subject_list = dataset.subject_list[0:1]

data_size = dict(policy="ratio", value=np.geomspace(0.02, 1, 6))
# When the training data is sparse, perform more permutations than when we have
# a lot of data
n_perms = np.floor(np.geomspace(20, 2, len(data_size["value"]))).astype(int)
