add_noise.RdAdd noise to one matrix.
add_noise(data, mean = 0, sd = 0.2, val_min = 0, val_max = 1)
| data | The matrix to disturb. |
|---|---|
| mean | The mean of the normal distribution of noises. |
| sd | The standard deviation of the normal distribution of noises. |
| val_min, | the minimum value of the matrix |
| val_max, | the maximal value of the matrix |
This function return the matrix with noise.
