1.项目介绍
通过用minist数据集进行训练，得到一个GAN模型，可以生成与minist数据集类似的图片。
GAN是一种生成模型，它的目的是通过学习真实数据的分布来生成新的数据。GAN由两个网络组成，一个是生成器（Generator），一个是判别器（Discriminator）。生成器的任务是从随机噪声中生成类似于真实数据的样本，判别器的任务是判断给定的样本是真实的还是生成的。GAN的训练过程可以看作是一种对抗博弈，生成器和判别器互相竞争，不断提高自己的能力，最终达到生成器生成的样本和真实数据分布一致，判别器无法区分真假的状态。通过GAN我们可以生成足以以假乱真的图像，GAN被广泛的应用在图像生成，语音生成等场景中。例如经典的换脸应用DeepFakes背后的技术便是GAN.

# latent_size：这是潜在向量的大小，用作生成器网络的输入以生成假图像。
#latent_size 的大小会影响生成图像的多样性和质量。如果 latent_size 太小，则生成器可能无法捕获数据分布的所有变化，从而导致生成图像缺乏多样性。如果 latent_size 太大，则生成器可能会过拟合训练数据，从而导致生成图像质量下降。
# hidden_size：这是隐藏层的大小，用于定义生成器和鉴别器网络中隐藏层的大小。
# image_size：这是图像的大小，表示图像的像素数。在这种情况下，图像被重塑为一维张量，因此图像大小等于图像的长度。
# num_epochs：这是训练期间整个数据集通过网络的次数。
# batch_size：每批次中图像的数量。

训练结果的展示
一开提供的minist的真实数据的图片
通过迭代1次过后生成器生成的图片
通过迭代10次过后生成器生成的图片
通过迭代50次过后生成器生成的图片
通过迭代103次过后生成器生成的图片
我们可以看到，随着迭代次数的增加，我们的生产起生成的图像逐渐的与minist数据的提供的数据图像相类似。
