Load data from [Nanduri2012]

Load the brightness and size rating data described in [Nanduri2012]. Datapoints were extracted from figure 4 of the paper using WebplotDigitizer.

Retinal implants: Argus I
Subjects: 1
Number of samples: 128
Number of features: 17

The dataset includes the following features:

subject Subject ID, S06
implant Argus I
electrode Electrode ID, A2, A4, B1, C1, C4, D2, D3, D4
task ‘rate’ or ‘size’
stim_class “Nanduri2012”
stim_dur Stimulus duration (ms)
freq Stimulus frequency (Hz)
amp_factor Stimulus amplitude ratio over threshold
brightness Patient rated brightness compared to reference stimulus
size Patient rated size compared to reference stimulus
ref_stim_class “Nanduri2012”
ref_amp_factor Amplitude factor (xTh) of reference pulse
ref_freq Frequency (Hz) of reference pulse
pulse_dur Pulse duration (ms)
pulse_type ‘cathodicFirst’
interphase_dur Interphase gap (ms)
varied_param Whether this trial is a part of ‘amp’ or ‘freq’ modulation

  • electrodes (str | list of strings | None, optional) – Select data from a single electrode or a list of electrodes. By default, all electrodes are selected.
  • shuffle (boolean, optional) – If True, the rows of the DataFrame are shuffled.
  • random_state (int | numpy.random.RandomState | None, optional) – Determines random number generation for dataset shuffling. Pass an int for reproducible output across multiple function calls.

data (pd.DataFrame) – The whole dataset is returned in a 144x16 Pandas DataFrame
