## Introduction to Machine Learning

What is Machine Learning?

In this tutorial, you will learn the basics of machine learning. Machine learning is a subfield of artificial intelligence (AI). It deals with the question of how to make computers “learn”.

Learning means getting better at something, usually by experience. For example, a child learns to recognize faces by seeing many faces and gradually learning to distinguish them. Similarly, a self-driving car learns to drive by watching many other cars drive and gradually learning the rules of the road.

Machine learning is closely related to and often used in conjunction with statistical techniques such as regression and classification. Machine learning can be used for both supervised learning and unsupervised learning.

Supervised learning is where you have training data that includes the correct answers (labels). The goal in supervised learning is to build a model that can make predictions on new data that has the same structure as the training data (features), but without the labels.

Unsupervised learning is where you have training data but no labels. The goal in unsupervised learning is to find some structure in the data or build a model that can describe the data well.

## What is TensorFlow?

In simple terms, TensorFlow is a library for doing large-scale numerical computations. In more technical terms, it is a “platform for machine learning applications.”

When you install TensorFlow, you get two main components:

* A library for doing computations involving Tensors (a Tensor is just a fancy name for an n-dimensional array). This is the core of TensorFlow.

* A tool for automatically constructing and optimizing computational graphs from code written in Python (or in a few other languages). This is called the TensorFlow Graphical Processing Unit (GPU).

You can use the library to do all sorts of interesting things, but one of the most popular applications is training neural networks.

## TensorFlow and Machine Learning

Machine learning is a field of computer science that uses statistical techniques to give computer systems the ability to “learn” (i.e., progressively improve performance on a specific task) with data, without being explicitly programmed. The name machine learning was coined in 1959 by Arthur Samuel. Machine learning explores the study and construction of algorithms that can learn from and make predictions on data. Such algorithms operate by building a model from example inputs in order to make data-driven predictions or decisions, rather than following strictly static program instructions. Machine learning is employed in a range of computing tasks where designing and programming explicit algorithms is infeasible; example applications include email filtering, detection of network intruders, and computer vision.

TensorFlow is an open source software library for machine learning across a range of tasks, and developed by Google to meet their needs for systems capable of building and training neural networks to detect and decipher patterns and correlations, analogous to the learning process that humans use to gain understanding. TensorFlow was originally developed by researchers and engineers working on the Google Brain Team within Google’s Machine Intelligence research organization for the purposes of conducting machine learning and deep neural networks research, but the system is general enough to be applicable in a wide variety of other domains as well.

## TensorFlow for Deep Learning

TensorFlow is a powerful tool for building and training deep learning models. In this tutorial, we will explore how to use TensorFlow to build and train a simple convolutional neural network (CNN) for image classification. We will also discuss some of the challenges involved in training deep learning models and how to overcome them.

## Getting Started with TensorFlow

In this tutorial, we’ll cover the basics of TensorFlow, how to build simple machine learning models with the library, and how to use some of its more advanced features. By the end of this guide, you’ll know how to:

– Install TensorFlow and related tools

– represent data using Tensors

– perform simple math operations on Tensors

– build simple machine learning models in TensorFlow

– train and evaluate those models

This tutorial is meant for readers who are new to both machine learning and TensorFlow. If you’re already familiar with one or the other (but not both), try our other intro tutorials first. For more experienced ML developers, we also provide an advanced ML Crash Course.

## Building a Model in TensorFlow

TensorFlow is a powerful tool for machine learning, but it can be difficult to get started. In this tutorial, we’ll walk you through the basics of building a model in TensorFlow. We’ll show you how to construct a computational graph, how to train your model, and how to evaluate its performance. By the end of this tutorial, you’ll be able to build and train simple models in TensorFlow.

Building a Model in TensorFlow

The first step in building a model in TensorFlow is to construct a computational graph. A computational graph is a way of representing your computation as a series of operations on Tensors. Tensors are the data structures that TensorFlow uses to represent your data.

To build a computational graph, you need to specify the operations that you want to perform on your Tensors. TensorFlow provides a collection of building blocks that you can use to construct yourgraphs. These building blocks are called ops (short for operations).

For example, suppose you want to add two numbers together. You can use the tf.add op to do this:

## Training and Evaluating a Model in TensorFlow

This tutorial will show you how to train and evaluate a model in TensorFlow. You will use the iris data set, which is a classic example of a machine learning problem. The data set contains 150 instances of irises, each with four features: sepal length, sepal width, petal length, and petal width. The task is to predict the species of an iris given its measurements. There are three species in the data set: setosa, versicolor, and virginica.

The first step is to import the TensorFlow library:

Next, you need to load the data set. The iris data set is built into TensorFlow, so you can simply use the tf.contrib.learn.datasets.load_iris() function:

Now that you have the data set loaded, you need to split it into training and test sets. You can do this using the train_test_split() function from the scikit-learn library:

Now that your data is split into training and test sets, you can define your model. For this tutorial, you will use a simple linear model with four features: sepal length, sepal width, petal length, and petal width. The model will have one weight for each feature and one bias term:

$$\hat{y} = w_1 x_1 + w_2 x_2 + w_3 x_3 + w_4 x_4 + b$$

$$\hat{y} = \text{predicted value}$$

$$w_i = \text{weight for feature } i$$

$$x_i = \text{feature } i$$

$$b = \text{bias term}$$

You can define the model in TensorFlow using the tf.contrib.learn library:
