Let’s see how a no-code platform could be useful with an instance.

Use Case

Mammalian fully-grown oocytes are categorized as a Surrounded Nucleolus (SN) or a Not Surrounded Nucleolus (NSN) primarily based on their chromatin configuration noticed after staining. We’ve got a dataset of pictures of mouse oocytes to be categorized as SN or NSN. The given downside is a machine studying classification downside the place the photographs should be categorized primarily based on their options. The dataset used within the instance could be discovered right here https://figshare.com/articles/dataset/Orange-Picture-Analytics/9632276?file=17282204

The above classification is achieved with the next Python program.

Step by Step Define of Code

Allow us to now undergo the steps.

Load pictures for each SN and NSN from the given listing and convert to array.

import matplotlib.pyplot as plt
import numpy as np
import PIL
import tensorflow as tf
import pandas as pd
import os
from tensorflow import keras
from tensorflow.keras import layers
from tensorflow.keras.fashions import Sequential
from tensorflow.keras.functions.inception_v3 import InceptionV3, preprocess_input
from tensorflow.keras. preprocessing import picture
from sklearn.metrics import pairwise_distances
from sklearn.manifold import MDS
from os import listdir


# get the trail/listing
folder_dir = "/content material/sample_data/OO/SN"
for pictures in os.listdir(folder_dir):

    # examine if the picture ends with jpg
    if (pictures.endswith(".jpg")):
        print(pictures)

    # examine if the picture ends with jpg  
folder_dir = "/content material/sample_data/OO/NSN"
for pictures in os.listdir(folder_dir):

    # examine if the picture ends with jpg
    if (pictures.endswith(".jpg")):
        print(pictures)

# Set the paths
