    "Quantifying a learning algorithm's performance and comparing different models are some of the common tasks when applying machine learning to real world applications. In this lab, you will practice doing these using the tips shared in class. Specifically, you will:\n",
    "\n",
    "* split datasets into training, cross validation, and test sets\n",
    "* evaluate regression and classification models\n",
    "* add polynomial features to improve the performance of a linear regression model\n",

    "This lab will also help you become familiar with the code you'll see in this week's programming assignment. Let's begin!"

    "In the previous course of this specialization, you saw that it is usually a good idea to perform feature scaling to help your model converge faster. This is especially true if your input features have widely different ranges of values. Later in this lab, you will be adding polynomial terms so your input features will indeed have different ranges. For example, $x$ runs from around 1600 to 3600, while $x^2$ will run from 2.56 million to 12.96 million. \n",
    "\n",
    "You will only use $x$ for this first model but it's good to practice feature scaling now so you can apply it later. For that, you will use the [`StandardScaler`](https://scikit-learn.org/stable/modules/generated/sklearn.preprocessing.StandardScaler.html) class from scikit-learn. This computes the z-score of your inputs. As a refresher, the z-score is given by the equation:\n",
    "\n",
    "$$ z = \\frac{x - \\mu}{\\sigma} $$\n",
    "\n",
    "where $\\mu$ is the mean of the feature values and $\\sigma$ is the standard deviation. The code below shows how to prepare the training set using the said class. You can plot the results again to inspect if it still follows the same pattern as before. The new graph should have a reduced range of values for `x`."

    "### Evaluate the Model\n",

Take note though that [as per the documentation](https://scikit-learn.org/stable/modules/model_evaluation.html#mean-squared-error), scikit-learn's implementation only divides by `m` and not `2*m` (where `m` = number of examples). Thus, to match the equation above, you can use the scikit-learn function then divide by two as shown below. We also included a for-loop implementation so you can check that it's equal. \n",
    "\n",
    "Another thing to take note: since you trained the model on scaled values (i.e. using the z-score), you should also feed in the scaled training set instead of its raw values."

    "* If you get this input sample's z-score using any other values of the mean and standard deviation, then it might not be scaled to `0.5` and your model will most likely make a wrong prediction (i.e. not equal to `y=300`). \n",

    "## Adding Polynomial Features\n",
    "\n",
    "From the graphs earlier, you may have noticed that the target `y` rises more sharply at smaller values of `x` compared to higher ones. A straight line might not be the best choice because the target `y` seems to flatten out as `x` increases. Now that you have these values of the training and cross validation MSE from the linear model, you can try adding polynomial features to see if you can get a better performance. The code will mostly be the same but with a few extra preprocessing steps. Let's see that below."

The code below demonstrates how to do this using the [`PolynomialFeatures`](https://scikit-learn.org/stable/modules/generated/sklearn.preprocessing.PolynomialFeatures.html) class. It will create a new input feature which has the squared values of the input `x` (i.e. degree=2)."

    "When selecting a model, you want to choose one that performs well both on the training and cross validation set. It implies that it is able to learn the patterns from your training set without overfitting. If you used the defaults in this lab, you will notice a sharp drop in cross validation error from the models with degree=1 to degree=2. This is followed by a relatively flat line up to degree=5. After that, however, the cross validation error is generally getting worse as you add more polynomial features. Given these, you can decide to use the model with the lowest `cv_mse` as the one best suited for your application."

    "### Evaluating the error for classification models\n",
    "\n",
    "In the previous sections on regression models, you used the mean squared error to measure how well your model is doing. For classification, you can get a similar metric by getting the fraction of the data that the model has misclassified. For example, if your model made wrong predictions for 2 samples out of 5, then you will report an error of `40%` or `0.4`. The code below demonstrates this using a for-loop and also with Numpy's [`mean()`](https://numpy.org/doc/stable/reference/generated/numpy.mean.html) function. "
