A visual introduction to machine learning In machine learning computers apply statistical learning techniques to automatically identify patterns in data These techniques can be used to make highly accurate predictions Keep scrolling Using a data set about homes we will create a machine learning model to distinguish homes in New York from homes in San Francisco Scroll First some intuition Lets say you had to determine whether a home is in San Francisco or in New York In machine learning terms categorizing data points is a classification task Since San Francisco is relatively hilly the elevation of a home may be a good way to distinguish the two cities Based on the homeelevation data to the right you could argue that a home above 73 meters should be classified as one in San Francisco Adding nuance Adding another dimension allows for more nuance For example New York apartments can be extremely expensive per square foot So visualizing elevation and price per square foot in a scatterplot helps us distinguish lowerelevation homes The data suggests that among homes at or below 73 meters those that cost more than 191167 per square meter are in New York City Dimensions in a data set are called features predictors or variables 1 Drawing boundaries You can visualize your elevation 73 m and price per square foot 191167 observations as the boundaries of regions in your scatterplot Homes plotted in the green and blue regions would be in San Francisco and New York respectively Identifying boundaries in data using math is the essence of statistical learning Of course youll need additional information to distinguish homes with lower elevations and lower persquarefoot prices The dataset we are using to create the model has 7 different dimensions Creating a model is also known as training a model On the right we are visualizing the variables in a scatterplot matrix to show the relationships between each pair of dimensions There are clearly patterns in the data but the boundaries for delineating them are not obvious And now machine learning Finding patterns in data is where machine learning comes in Machine learning methods use statistical learning to identify boundaries One example of a machine learning method is a decision tree Decision trees look at one variable at a time and are a reasonably accessible though rudimentary machine learning method Finding better boundaries Lets revisit the 73m elevation boundary proposed previously to see how we can improve upon our intuition Clearly this requires a different perspective By transforming our visualization into a histogram we can better see how frequently homes appear at each elevation While the highest home in New York is 73m the majority of them seem to have far lower elevations Your first fork A decision tree uses ifthen statements to define patterns in data For example if a homes elevation is above some number then the home is probably in San Francisco In machine learning these statements are called forks and they split the data into two branches based on some value That value between the branches is called a split point Homes to the left of that point get categorized in one way while those to the right are categorized in another A split point is the decision trees version of a boundary Tradeoffs Picking a split point has tradeoffs Our initial split 73 m incorrectly classifies some San Francisco homes as New York ones Look at that large slice of green in the left pie chart those are all the San Francisco homes that are misclassified These are called false negatives However a split point meant to capture every San Francisco home will include many New York homes as well These are called false positives The best split At the best split the results of each branch should be as homogeneous or pure as possible There are several mathematical methods you can choose between to calculate the best split 2 As we see here even the best split on a single feature does not fully separate the San Francisco homes from the New York ones Recursion To add another split point the algorithm repeats the process above on the subsets of data This repetition is called recursion and it is a concept that appears frequently in training models 3 The histograms to the left show the distribution of each subset repeated for each variable The best split will vary based which branch of the tree you are looking at 4 For lower elevation homes price per square foot is at 1061 per sqft is the best variable for the next ifthen statement For higher elevation homes it is price at 514500 Growing a tree Additional forks will add new information that can increase a trees prediction accuracy Splitting one layer deeper the trees accuracy improves to 84 Adding several more layers we get to 96 You could even continue to add branches until the trees predictions are 100 accurate so that at the end of every branch the homes are purely in San Francisco or purely in New York These ultimate branches of the tree are called leaf nodes Our decision tree models will classify the homes in each leaf node according to which class of homes is in the majority Making predictions The newlytrained decision tree model determines whether a home is in San Francisco or New York by running each data point through the branches Here you can see the data that was used to train the tree flow through the tree This data is called training data because it was used to train the model Because we grew the tree until it was 100 accurate this tree maps each training data point perfectly to which city it is in Reality check Of course what matters more is how the tree performs on previouslyunseen data To test the trees performance on new data we need to apply it to data points that it has never seen before This previously unused data is called test data Ideally the tree should perform similarly on both known and unknown data So this one is less than ideal 5 These errors are due to overfitting Our model has learned to treat every detail in the training data as important even details that turned out to be irrelevant Overfitting is part of a fundamental concept in machine learning explained in our next post 6 Recap Machine learning identifies patterns using statistical learning and computers by unearthing boundaries in data sets You can use it to make predictions One method for making predictions is called a decision trees which uses a series of ifthen statements to identify boundaries and define patterns in the data Overfitting happens when some boundaries are based on on distinctions that dont make a difference You can see if a model overfits by having test data flow through the model Coming up next Next we explore overfitting and how it relates to a fundamental tradeoff in machine learning Check out Part II Model Tuning and the BiasVariance Tradeoff Questions Thoughts We would love to hear from you Tweet us at r2d3us or email us at teamr2d3us or Facebook A visual introduction to machine learning Posted by R2D3 on or keep in touch with email Footnotes Machine learning concepts have arisen across disciplines computer science statistics engineering psychology etc thus the different nomenclature To learn more about calculating the optimal split search for gini index or cross entropy One reason computers are so good at applying statistical learning techniques is that theyre able to do repetitive tasks very quickly and without getting bored The algorithm described here is greedy because it takes a topdown approach to splitting the data In other words it is looking for the variable that makes each subset the most homogeneous at that moment Hover over the dots to see the path it took in the tree Spoiler alert Its the biasvariance tradeoff
