Chapter 05, Page no 116, Table 5.1 - Fixed description as per table cells

Here is how we define the cells:

  • TP (true positives): These are located in the lower-right cell, containing examples that have been correctly predicted as positive ones.
  • FP (false positives): These are located in the upper-right cell, containing examples that have been predicted as positive but are actually negative.
  • FN (false negatives): These are located in the lower-left cell, containing examples that have been predicted as negative but are actually positive.
  • TN (true negatives): These are located in the upper-left cell, containing examples that have been correctly predicted as negative ones.

Chapter 05, Page no 110, Mean squared error (MSE) and R squared

Following is the correct formula for R squared "co-efficient of determination":

Chapter 05, Page no 121, correct reference to the panel in an image

The first paragraph says: "A bad classifier can be spotted by the ROC curve appearing very similar, if not identical, to the diagonal of the chart, which represents the performance of a purely random classifier, as in the top right of Figure 5.3; ROC-AUC scores near 0.5 are considered to be almost random results."

Chapter 05, Page no 130, typo in the name of the model SSD

The last line of the note should say: ".....YOLO (https://arxiv.org/abs/1506.02640v1), Faster R-CNN https://arxiv.org/abs/1506.01497v1), or SSD (https://arxiv.org/abs/1512.02325)."

Chapter 06, Page no 183, reference to test case number

Change "only 1,495" to "about 24,500"

Chapter 06, Page no 184, feature_19 and feature_54

Instead of feature_19 and feature_54, the correct features that appear the most different between the training/test split are cont14, cont4, and cont5.
