Overview of this book

We’re witnessing a revolution in Artificial Intelligence, thanks to breakthroughs in deep learning. Mobile Artificial Intelligence Projects empowers you to take part in this revolution by applying Artificial Intelligence (AI) techniques to design applications for natural language processing (NLP), robotics, and computer vision. This book teaches you to harness the power of AI in mobile applications along with learning the core functions of NLP, neural networks, deep learning, and mobile vision. It features a range of projects, covering tasks such as real-estate price prediction, recognizing hand-written digits, predicting car damage, and sentiment analysis. You will learn to utilize NLP and machine learning algorithms to make applications more predictive, proactive, and capable of making autonomous decisions with less human input. In the concluding chapters, you will work with popular libraries, such as TensorFlow Lite, CoreML, and PyTorch across Android and iOS platforms. By the end of this book, you will have developed exciting and more intuitive mobile applications that deliver a customized and more personalized experience to users.

Building a feedforward neural network to recognize handwritten digits, version two

In the previous section, we built a very simple neural network with just an input and output layer. This simple neural network gave us an accuracy of 86%. Let's see if we can improve this accuracy further by building a neural network that is a little deeper than the previous version:

  1. Let's do this on a new notebook. Loading the dataset and data pre-processing will be the same as in the previous section:
import numpy as np
import keras
from keras.datasets import mnist
from keras.models import Sequential
from keras.layers import Dense
from keras.optimizers import SG
#loading and pre-processing data
(X_train,y_train), (X_test,y_test)= mnist.load_data() X_train= X_train.reshape( 60000, 784). astype('float32')
X_test =X_test.reshape(10000,784).astype('float32&apos...
