Which machine learning algorithm should the researchers use that BEST meets their requirements?
Latent Dirichlet Allocation (LDA)
Recurrent neural network (RNN)
K-means
Convolutional neural network (CNN)
Explanations:
Latent Dirichlet Allocation (LDA) is a topic modeling technique primarily used for discovering abstract topics from a collection of documents. It is not suited for image classification tasks like detecting whether individuals are wearing a specific brand.
Recurrent Neural Networks (RNNs) are designed for sequential data and are typically used in tasks like natural language processing. They are not ideal for image data, where spatial hierarchies and patterns are crucial.
K-means is a clustering algorithm that is used to partition data into clusters based on feature similarity. It does not provide the classification capabilities needed to identify if individuals in images are wearing a specific brand.
Convolutional Neural Networks (CNNs) are specifically designed for image processing and classification tasks. They can effectively learn spatial hierarchies and patterns in images, making them the best choice for detecting brand presence in images.
