Testing the baseline model

In this section, we will be implementing our testing approach so that we can evaluate our model's accuracy. We will first generate the output prediction and then we'll start testing it. We will be implementing the following steps here:

1. Generating and interpreting the output

2. Generating the score

3. Visualizing the output

Generating and interpreting the output

To generate the prediction, we are using the treeinterpreter library. We are predicting the price value for each of our testing dataset records using the following code:

Figure 2.26: Code snippet for generating the prediction

Here, prediction is the array in which we have elements that are the corresponding predicted adj close price for all records of the testing dataset. Now, we will compare this predicted output with the actual adj close price of the testing dataset. By doing this, we will get to know how accurately our first model is predicting the adj close price. In order to evaluate further, we will generate...
