B. Feedforward Neural Network (FNN)
C. Convolutional Neural Network (CNN)
D. Radial Basis Function Network (RBFN)
Answer
A. Recurrent Neural Network (RNN)
Explanation
RNNs are designed to handle sequential data such as text or time series. RNNs are a class of artificial neural networks specifically designed to recognize patterns in sequences of data, such as text, speech, or time-series data.
Recurrent Neural Networks (RNNs) are uniquely suited for sequential data because they possess a form of memory. Unlike other neural networks that process inputs independently, an RNN has internal loops that allow information to persist from one step of the sequence to the next. This is achieved by feeding the output of a neuron back into it as an input for the next instance, creating a hidden state that acts as a memory of the preceding elements in the sequence. This mechanism is crucial for tasks like sentiment analysis, where the meaning of a word often depends on the words that came before it.
Feedforward Neural Network (FNN): An FNN processes inputs in only one direction—from input to output—and has no memory of past inputs. It treats every piece of input data as independent, making it unsuitable for understanding the context and order inherent in sequential data like sentences.
Convolutional Neural Network (CNN): While CNNs can be adapted for text classification by treating text as a one-dimensional grid, their primary strength lies in detecting local patterns and spatial hierarchies, such as in image recognition. They are generally less effective than RNNs at capturing long-range dependencies and the contextual flow of language.
Radial Basis Function Network (RBFN): RBFNs are typically used for function approximation and classification. They work by measuring the distance of an input from a central point and do not have an inherent architecture for processing data that has a sequential order.
