You work for an online retailer as a machine learning specialist.
Your team has been tasked with creating a machine learning model to identify similar products for a product comparison chart on many of the product pages on your website.
Your website designers want to show a grid of a product compared to similar products, even products from competitors.
The grid will show the price, review summary (stars), and key features of each product.
You are at the stage in your development where you are gathering, cleaning, and transforming your data and training your model. Using machine learning techniques, how can you determine similar product data for use in this grid in the most efficient manner?

A. B. C. D. E. F.Answer: D.
Option A is incorrect.
Using a Linear Learner algorithm-based model with the binary_classifier predictor_type may help you find similar products, but it is not the most efficient technique listed in the options.
Option B is incorrect.
Using the XGBoost algorithm-based model with the reg:logistic objective may help you find similar products, but it is not the most efficient technique listed in the options.
Option C is incorrect.
Using the Linear Learner algorithm with the regressor predictor_type would not be a good choice for a discrete categorization problem such as matching similar products.
Option D is correct.
The LakeFormation FindMatches transformation can be used to find similar products in your data stores and even external data sources, such as those of competitor products.
Option E is incorrect.
Using the XGBoost algorithm with the reg:linear objective would not be a good choice for a discrete categorization problem such as matching similar products.
Option F is incorrect.
The AWS Glue FindMatches ML Transform uses machine learning capabilities to find matching records in your database, even when the records don't have exactly matching fields.
Setting the FindMatches ML Transform precision_recall parameter to recall is incorrect since this setting is used when you want to minimize false negatives.
Meaning, the ML transform failed to find a match when a match actually existed.
This is not an optimal result, but it is a better outcome than incorrectly identifying two items as similar when they really aren't (false positive).

To determine similar product data efficiently, you will need to use a machine learning technique that can compare and match different products based on their attributes such as price, review summary, and key features. The most appropriate option for this scenario would be a similarity-based approach using a recommender system. Recommender systems are used to suggest items that users are likely to be interested in, based on their historical preferences or actions.
To create a recommender system, you will need to use machine learning algorithms that can learn from historical user-item interactions to make personalized recommendations. There are several types of recommender systems, but the most commonly used ones are Collaborative Filtering and Content-Based Filtering.
Collaborative Filtering: Collaborative filtering is a type of recommender system that makes recommendations based on the behavior of similar users. In this approach, the algorithm first identifies groups of users with similar behavior, then recommends items that those users have liked or bought in the past. Collaborative filtering can be further classified into two categories: User-Based Collaborative Filtering and Item-Based Collaborative Filtering.
Content-Based Filtering: Content-based filtering is a type of recommender system that makes recommendations based on the attributes of items. In this approach, the algorithm learns the characteristics of each item and recommends similar items based on their attributes.
Given the problem statement, the most appropriate approach is to use a Content-Based Filtering technique, where you can train a machine learning model on historical product data and extract features such as price, review summary (stars), and key features. Once you have extracted these features, you can compare and match different products based on their similarity scores.
To implement the Content-Based Filtering technique, you can use a variety of machine learning algorithms such as Linear Learner, XGBoost, or any other suitable algorithm. In this scenario, the best options are the Linear Learner or XGBoost algorithms built-in SageMaker.
Linear Learner is a binary classification or regression algorithm that can learn linear relationships between features and output labels. It works well for binary classification problems such as predicting whether a product is similar or not. You can set the predictor_type hyperparameter to either binary_classifier or regressor depending on the problem statement.
XGBoost is a decision-tree-based algorithm that works well for regression or classification problems. It is a popular algorithm for building recommender systems because of its ability to handle large datasets and complex feature interactions. You can set the objective hyperparameter to either reg:logistic or reg:linear depending on the problem statement.
AWS LakeFormation FindMatches ML Transform and AWS Glue FindMatches ML Transform are used for data deduplication or record linkage and are not suitable for the problem statement in this scenario.
In conclusion, the most appropriate options for determining similar product data for use in the grid are A. Use the Linear Learner built-in SageMaker algorithm and set its predictor_type hyperparameter to binary_classifier, or B. Use the XGBoost built-in SageMaker algorithm and set its objective hyperparameter to reg:logistic.
