Study Notes

Neural Networks and Fashion MNIST

  • A CNN (Convolutional Neural Network) architecture is used in the example for image classification.
  • The Fashion MNIST dataset is used for image classification.
  • There are 10 classes in the Fashion MNIST dataset.
  • Each image in the Fashion MNIST dataset is 28x28 pixels in size.
  • According to Zalando, the purpose of the Fashion-MNIST dataset is to serve as a replacement for the MNIST dataset.
  • There are 60,000 examples in the training set of the Fashion MNIST dataset.
  • A fully connected layer is used for classification in the example's CNN architecture.

Mitosis and Meiosis

  • Mitosis produces 2 daughter cells, while meiosis produces 4 daughter cells.
  • In mitosis, the ploidy level of daughter cells remains the same as the parent cell, whereas in meiosis, the ploidy level of daughter cells is halved.
  • Meiosis involves 2 rounds of cell division, whereas mitosis involves only 1 round.
  • Mitosis occurs in somatic cells, while meiosis exclusively occurs in gamete-producing cells (germ cells).
  • The primary purpose of mitosis in lower organisms is to produce more individuals.
  • The stages of meiosis I and meiosis II differ from the stages of mitosis in terms of the presence of crossing over and the separation of homologous chromosomes.
  • Daughter cells produced by mitosis are genetically identical, whereas daughter cells produced by meiosis are genetically diverse.
  • Meiosis plays a crucial role in sexual reproduction by increasing genetic diversity.
  • Prophase in meiosis I is longer and has more sub-stages than in mitosis.
  • Daughter cells produced by meiosis are haploid, whereas daughter cells produced by mitosis are diploid.
