    "## 1. Decision Trees\n",
    "One of the great advantages of decision trees is their interpretability. The rules learnt for classification are easy for a person to follow, unlike the opaque \"black box\" of many other methods, such as neural networks. We demonstrate the utility of this using a German credit data set. You can read a description of this dataset at the [UCI site](http://archive.ics.uci.edu/ml/datasets/Statlog+%28German+Credit+Data%29). The task is to predict whether a loan approval is good or bad credit risk based on 20 attributes. We've simplified the data set somewhat, particularly making attribute names and values more meaningful."

    "When presented with a dataset, it is usually a good idea to visualise it first. By using seaborn's [pairplot](https://stanford.edu/~mwaskom/software/seaborn/generated/seaborn.pairplot.html) function, try visualising a scatter plot of the `Age` and `Duration` variables. You can use the `Approve` variable as the `hue` parameter to visualise results separately for each class. Do you notice anything unusual?"

A good way to check this is to test the performance of each classifier before and after removing this datapoint."

    "It seems like the variables `Duration`, `CreditAmount` and `Age` are continuous and all the rest are discrete. The discrete variables are not in a very convenient format though. Ideally we would want the discrete attributes to take values between `0` and `n_values-1`. Scikit-learn has a handy [`LabelEncoder`](http://scikit-learn.org/0.17/modules/generated/sklearn.preprocessing.LabelEncoder.html#sklearn.preprocessing.LabelEncoder) implementation which can do that for us. You are encouraged to read its documentation.\n",

    "Now we will create a new DataFrame called `credit_clean` and convert all the discrete variables from `credit` by using a `LabelEncoder`. Remember, we want to change the discrete variables only, so we will have to exclude the `CreditAmount`, `Age` and `Duration` attributes. Also, we don't really mind if the target variable is categorical, so we won't be transforming the `Approve` attribute either. Execute the cell below and make sure you understand what it does."

One way to force the tree to think of these categories as separate is to use a `OnehotEncoder` but, in practice, because the tree can separate the classes it needs by using multiple splitting conditions, this isn't usually a problem. An example of where it is a problem would be if an important condition was if `CheckingAccount` was  '<0' or 'none'.

For this purpose we will use once again seaborn's pairplot implementation.\n",
