想想如果没有机器学习,做这样的事情会有多困难。如何编写代码来对任何语言的任何
字符进行光学字符识别。然后,一旦你这样做了,如何在没有翻译服务器的情况下翻译这
些文件。这根本不可行。但是机器学习,尤其是设备上的机器学习,正在使这成为可能。
8.2 TensorFlow Lite
入门
要了解 TensorFlow Lite,我认为最容易的是上手并立即使用它。让我们首先探索采用
TensorFlow 模型并将其转换为 TensorFlow Lite 格式的转换器。然后我们将使用它创建的
模型并在一个简单的 Android 应用程序中实现它。
在第 1 章中,我们编写了一些我们称之为机器学习“Hello World”的代码,使用非常简单
的线性回归来构建一个模型,该模型可以预测两个数字
x
y
之间的关系,即
y
= 2
x
– 1
回顾一下,这是在 TensorFlow 中训练模型的 Python 代码:
import tensorflow as tf
import numpy as np
from tensorflow.keras import Sequential
from tensorflow.keras.layers import Dense
layer_0 = Dense(units=1, input_shape=[1])
model = Sequential([layer_0])
model.compile(optimizer='sgd', ...
