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?
A. k-means, because this is a clustering problem with a small number of features.
B. A decision tree algorithm, because the problem is a classification problem with a small number of features.
C. Logistic regression, because this is a classification problem and our data is linearly separable.
D. Neural network model, because this is a classification problem with a large number of features.
正解：D
解説：
Explanation
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.

Which of the following regressions will help when there is the existence of near-linear relationships among the independent variables (collinearity)?
A. Clustering
B. Polynomial regression
C. Linear regression
D. Ridge regression
正解：D
解説：
Ridge regression is a type of regularization technique that can help reduce collinearity among independent variables. It does this by adding a penalty term to the ordinary least squares (OLS) objective function, which shrinks the coefficients of highly correlated variables towards zero. This reduces the variance of the coefficient estimates and improves the stability and accuracy of the regression model.

Which of the following sentences is TRUE about the definition of cloud models for machine learning pipelines?
A. Platform as a Service (PaaS) can provide some services within an application such as payment applications to create efficient results.
B. Software as a Service (SaaS) can provide AI practitioner data science services such as Jupyter notebooks.
C. Data as a Service (DaaS) can host the databases providing backups, clustering, and high availability.
D. Infrastructure as a Service (IaaS) can provide CPU, memory, disk, network and GPU.
正解：B
解説：
Explanation
Cloud models are service models that provide different levels of abstraction and control over computing resources in a cloud environment. Some of the common cloud models for machine learning pipelines are:
Software as a Service (SaaS): SaaS provides ready-to-use applications that run on the cloud provider's infrastructure and are accessible through a web browser or an API. SaaS can provide AI practitioner data science services such as Jupyter notebooks, which are web-based interactive environments that allow users to create and share documents that contain code, text, visualizations, and more.
Platform as a Service (PaaS): PaaS provides a platform that allows users to develop, run, and manage applications without worrying about the underlying infrastructure. PaaS can provide some services within an application such as payment applications to create efficient results.
Infrastructure as a Service (IaaS): IaaS provides access to fundamental computing resources such as servers, storage, networks, and operating systems. IaaS can provide CPU, memory, disk, network and GPU resources that can be used to run machine learning models and applications.
Data as a Service (DaaS): DaaS provides access to data sources that can be consumed by applications or users on demand. DaaS can host the databases providing backups, clustering, and high availability.
質問 # 15
A healthcare company experiences a cyberattack, where the hackers were able to reverse-engineer a dataset to break confidentiality.
Which of the following is TRUE regarding the dataset parameters?
A. The model is overfitted and trained on a low quantity of patient records.
B. The model is underfitted and trained on a high quantity of patient records.
C. The model is overfitted and trained on a high quantity of patient records.
D. The model is underfitted and trained on a low quantity of patient records.
正解：A
解説：
Explanation
Overfitting is a problem that occurs when a model learns too much from the training data and fails to generalize well to new or unseen data. Overfitting can result from using a low quantity of training data, a high complexity of the model, or a lack of regularization. Overfitting can also increase the risk of reverse-engineering a dataset from a model's outputs, as the model may reveal too much information about the specific features or patterns of the training data. This can break the confidentiality of the data and expose sensitive information about the individuals in the dataset .
質問 # 16
Which of the following is the definition of accuracy?
A. True Positives / (True Positives + False Positives)
B. True Positives / (True Positives + False Negatives)
C. (True Positives + False Positives) / Total Predictions
D. (True Positives + True Negatives) / Total Predictions
正解：D
解説：
Accuracy is a measure of how well a classifier can correctly predict the class of an instance. Accuracy is calculated by dividing the number of correct predictions (true positives and true negatives) by the total number of predictions. True positives are instances that are correctly predicted as positive (belonging to the target class). True negatives are instances that are correctly predicted as negative (not belonging to the target class).
