Question

Write a Python program for applying CNN with considering the following requirements:

  • Shuffle the cifar 10 training set x_train( each input with corresponding label in y_train )
  • Select 2500 images and you must ensure that each class must contain at least 180 samples
  • Apply CNN that keeps noisy examples. Overall, the pseudocode of CNN is as follows:
  • The code must contain at least one lambda expression
  • The code must contain at one comprehension list
  • It is Not allowed to use the numpy library.

Euclidean distance is the distance between two samples in Euclidean space. The formula can be expressed as:

Condensed Nearest Neighbor (CNN)
Data reduction techniques aim to simplify the training data by removing noisy and redundant data, so that, machine learning algorithms can learn faster with
little or no performance degradation, as if the entire training set T is used.
CNN was the first data reduction Algorithm. This algorithm is an incremental method that starts with adding one example of each class to the subset S
randomly from training set T. Then, for each example x in T is classified using the examples in S. if the example x is incorrectly classified, it will be added to
S. This guarantees all instances in T are classified correctly. Based on this criterion, noisy examples will be retained because they are commonly classified
wrongly by their k – NN (whrere k = 1)
The CIFAR-10 dataset The CIFAR-10 dataset consists of 60000 32x32 colour images in 10 classes, with 6000 images per class. There are 50000 training
images and 10000 test images.
In order to load CIFAR-10 dataset, First, download tensorflow library using the following command:
install tensorflow
Then, use the following code:
In [63]: import tensorflow
import cv2
from tensorflow import keras
from PIL import Image
import numpy as p
(x_train, y_train), (_, _) = tf.keras.datasets.cifar10.load_data()
x_train = [cv2.cvtColor(image, cv2.COLOR_BGR2GRAY).flatten().tolist() for image in x_train]
##x_train=np.asarray(x_train)
print(len(x_train))
print(len(x_train[0])) # 32*32
