Which model should be used for categorizing new products using the provided dataset for training?
AnXGBoost model where the objective parameter is set to multi:softmax
A deep convolutional neural network (CNN) with a softmax activation function for the last layer
A regression forest where the number of trees is set equal to the number of product categories
A DeepAR forecasting model based on a recurrent neural network (RNN)
Explanations:
XGBoost is a gradient boosting algorithm that can handle classification tasks. Setting the objective tomulti:softmaxallows it to predict one of the multiple categories for each product. This is appropriate for the problem as it is a classification task with multiple categories.
A deep convolutional neural network (CNN) is generally used for image or spatial data processing, not for tabular data. The features in this case are not images, so using a CNN is not suitable.
A regression forest is a type of model used for regression tasks, not classification. The task here is multi-class classification, and regression forests are not designed for such problems.
DeepAR is a forecasting model based on RNNs, typically used for time-series forecasting, not classification. Since the task is categorizing products based on features, this model is not appropriate.
