Formatting Data#

All Bingo equations expect data to be formatted based on the number of variables and datapoints in the dataset.

Input#

Bingo expects that input data is formatted with each variable as a column and each datapoint as a row.

Layout of inputs:

$i$	$X_{0}$	$X_{1}$	$\dots$	$X_{n}$
0	0.1	1.2	$\dots$	1.2
1	0.1	2.3	$\dots$	3.5
2	0.1	1.2	$\dots$	6.0
$⋮$	$⋮$	$⋮$	$⋮$	$⋮$

Note

Bingo starts counting at 0, so $X_{0}$ is the first variable, $X_{1}$ is the second, and so on.

So, if we had 2 variables and 10 samples, we would have an array with 10 rows and 2 columns:

import numpy as np
X_0 = np.linspace(1, 10, num=10).reshape((-1, 1))
X_1 = np.linspace(-10, 1, num=10).reshape((-1, 1))
X = np.hstack((X_0, X_1))

Bingo expects output data to be formatted as a of the same number of samples as the input.

Layout of output:

$i$	$0$	$1$	$\dots$	$n$
$y_{i}$	0.0	-1.1	$\dots$	5.0

Using the previous setup, let’s create output data by using the equation $5.0 * X_{0} + X_{1}$ :

y = 5.0 * X_0 + X_1
