Subheading: Reproducibility

Under the heading "reproducibility", the 3rd paragraph starts with: "In order to address this problem of **repeatability** ", it should ideally be reproducibility instead of repeatability.

Note from the Author or Editor:
yes, please change "repeatability" to "reproducibility"

Figure 2-1, formula

In the formula in the figure it states f(x1,x1)=((1 && x2)... where it should be f(x1,x2)=((x1 && x2)...

Figure 2-15

On the left table in Figure 2-15, the label for AD should be - and the label for BD should be +. The left table in Figure 2-15 is not compatible with the conceptual plot on the right.

Note from the Author or Editor:
This is indeed a mistake. As the suggestions notes, in Figure 2-15, in the table on the left, the label for AD should be - and the label for BD should be +.

Figure 3-7

It would be more correct to change Figure 3-6 to a diagram like the one at the top of Sigmoid function's page of Wikipedia (https://en.wikipedia.org/wiki/Sigmoid_function) ? Since the domain of Sigmoid function is usually [-∞, ∞] and the range is [0, 1].

Note from the Author or Editor:
Yes, the domain of sigmoid is -inf to +inf and the range is from (0,1) exclusive. Also, the y-intercept of the sigmoid function is 0.5. The current figure is a bit misleading with respect to these properties and it would be more clear to as figure similar to the one in Wikipedia as suggested by the reviewer.

1st paragraph, 2nd bullet point

Mixed Input Representation is listed as a solution to a described problem (2nd bullet point. However, I could not find a description of what is Mixed Input Representation in the book.

Note from the Author or Editor:
Change "Mixed Input Representation" to "Multimodal Input"

Table 3-6, 3-7

Table 3-6 and Table 3-7 show the distances between specific data points and the centroid of the four clusters, so should they be following? Figure 3-6: CENTROID_ID DISTANCE -------------------------------- 4 0.29998627812137374 1 1.2370167418282159 2 1.376651161584178 3 1.6853517159990536 Figure 3-7: CENTROID_ID DISTANCE ------------------------------ 3 3.061985789261998 4 3.3124603501734966 2 4.330205096751425 1 4.658614918595627

Note from the Author or Editor:
The way the table is currently printed is a mistake. The table should consist of three columns with the column titles CENTROID_ID, NEAREST_CENTROIDS_DISTANCE.CENTROID_ID and DISTANCE. The table should be as follows: CENTROID_ID | NEAREST_CENTROIDS_DISTANCE.CENTROID_ID | NEAREST_CENTROIDS_DISTANCE.DISTANCE ---------------------------------------------------------------- 4 | 4 | 0.29998627812137374 | 1 | 1.2370167418282159 | 2 | 1.376651161584178 | 3 | 1.6853517159990536 CENTROID_ID | NEAREST_CENTROIDS_DISTANCE.CENTROID_ID | NEAREST_CENTROIDS_DISTANCE.DISTANCE ---------------------------------------------------------------- 3 | 3 | 3.061985789261998 | 4 | 3.3124603501734966 | 2 | 4.330205096751425 | 1 | 4.658614918595627

4th paragraph, last line

examples from the *minority* class. should be examples from the *majority* class.

Note from the Author or Editor:
This suggestion is correct. The sentence "Additionally, as mentioned by SMOTE, the approach of generating synthetic examples from the minority class is often combined with removing a random sample of examples from the minority class." should instead read: "Additionally, as mentioned by SMOTE, the approach of generating synthetic examples from the minority class is often combined with removing a random sample of examples from the majority class."

> - An instance of tfx.orchestration.pipeline (https://oreil.ly/62kf3) where we define our pipeline and the components it includes. > - An instance of kubeflow_dag_runner (https://oreil.ly/62kf3) from the tfx (https://oreil.ly/62kf3) library. We'll use this to create and run our pipeline. All three URLs are the same. If these shortened URLs are developed, I get "https://www.nhc.noaa.gov/aboutsshws.php", but it does not seem to be relevant in this context. Each of these three URLs should be as follows? 1st URL -> https://github.com/tensorflow/tfx/blob/master/tfx/orchestration/pipeline.py 2nd URL -> https://github.com/tensorflow/tfx 3rd URL -> https://github.com/tensorflow/tfx/blob/master/tfx/orchestration/kubeflow/kubeflow_dag_runner.py

Step 8 in the ML Lifecycle diagram should be "Plan for deployment" not "Plan for development"
