Using/Tesgin PyTorch SubSetRandSampler
import torch
from torch.utils.data import SubsetRandomSampler as SubSetRandSampler
import torchvision.transforms as transforms
import torchvision.datasets as datasets
import matplotlib.pyplot as plt
my_sampler_size = 5000 # I'm going to randomly sample 5000 items from the dataset
# Why using this instead of shuffle? Because I want to get less samples than the whole dataset
# would using an if statement inside the validation function be good ... something like if i>my_sampler_size: break

morawi / Multi-label pair-wise distance accepting ground truth labels as input
Created March 12, 2019 14:24
The purpose of this implemention is to find the correctly identified samples from predictions made with some AI/ML model. The incorrect labels can also be found. The function accepts three inputs; the predictions, the ground truth and their labels. It implements a pair-wise distance metric to find the proximity, based on the minimum distance, be…
