CertNexus AIP-210 Exam - Topic 4 Question 12 Discussion

Actual exam question for CertNexus's AIP-210 exam

Question #: 12
Topic #: 4

An organization sells house security cameras and has asked their data scientists to implement a model to detect human feces, as distinguished from animals, so they can alert th customers only when a human gets close to their house.

Which of the following algorithms is an appropriate option with a correct reason?

AA decision tree algorithm, because the problem is a classification problem with a small number of features.

Bk-means, because this is a clustering problem with a small number of features.

CLogistic regression, because this is a classification problem and our data is linearly separable.

DNeural network model, because this is a classification problem with a large number of features.

Show Suggested Answer

Suggested Answer: D

Neural network models are suitable for classification problems with a large number of features, because they can learn complex and non-linear patterns from high-dimensional data. They can also handle image data, which is likely to be the input for the human face detection problem. Neural networks can also be trained using transfer learning, which can leverage pre-trained models on similar tasks and improve the accuracy and efficiency of the model.

K-means? That doesn't seem right for classification!

Sounds like a decision tree could work well here!

Neural networks might be overkill for this, but I recall them being effective with complex data. I wonder if that's necessary here.

Logistic regression sounds familiar, especially for binary outcomes, but I’m not confident about the linear separability part.

I think k-means is more about clustering, right? This seems more like a classification task to me.

I remember we discussed decision trees being good for classification problems, but I'm not sure if they handle this specific scenario well.

A neural network could also work well for this type of problem, especially if there are a lot of features involved. The model should be able to learn the complex patterns in the data.

I'm leaning towards logistic regression for this one. It's a classic classification algorithm, and the data seems linearly separable, which is a good fit.

Hmm, I'm not sure if a decision tree is the best approach here. The problem seems more like a clustering task, so I might lean towards k-means instead.

This is an interesting problem, and I think a decision tree algorithm could be a good fit since it's a classification problem with a small number of features.

I'm pretty confident this is a recession - the question describes low employment and production, which matches the definition of a recession.

Yeah, I think B is correct too, since focusing on existing customers in a mature market seems crucial for earnings.

This looks like a straightforward wireless network design question. I'll need to carefully consider the requirements and match them to the available options.

This seems like a straightforward question to me. The answer is clearly A - minimizing harm to the affected individuals. The company needs to notify them, help prevent fraud, and take steps to protect their data going forward. The other options don't seem as relevant or important in this situation.

Hmm, I'm a little unsure on this one. The question mentions a few different security controls, so I'll need to think through which one covers all of those elements. Let me re-read the options carefully.
