Es decir, la columna de índice 1 contiene el píxel de la esquina superior izquierda de cada imagen. La columna de índice 28 contiene el píxel de la esquina superior derecha, y la columna de índice 29 contiene el píxel izquierdo de la segunda fila de la imagen.
Ahora llevamos a las variables <strong>X</strong> e <strong>y</strong> las características predictivas y la etiqueta, respectivamente:

Hay 60.000 muestras. El número de columnas es de (28 x 28) + 1 = 785. Concretamente la primera columna (la columna de índice 0) contiene la etiqueta de cada muestra (el número representado en la imagen) y las 784 restantes contienen los píxels de la imagen, habiéndose registrado éstos de izquierda a derecha y de arriba abajo:
<a class="colorbox insert-colorbox" data-colorbox-gallery="gallery-node" data-insert-class="" data-insert-type="image" href="/sites/default/files/2020-09/tutdl_0074.jpg"></a>
Es decir, la columna de índice 1 contiene el píxel de la esquina superior izquierda de cada imagen. La columna de índice 28 contiene el píxel de la esquina superior derecha, y la columna de índice 29 contiene el píxel izquierdo de la segunda fila de la imagen.
Ahora llevamos a las variables <strong>X</strong> e <strong>y</strong> las características predictivas y la etiqueta, respectivamente:
y = data.pop(0)
X = data
Por último, mostramos en pantalla el primer dígito, que contiene un "5":
y[0]
5
plt.imshow(X.iloc[0, :].values.reshape(28, 28), cmap = "binary_r");
