Natural Language Processing (NLP) is the subfield of Artificial Intelligence (AI) that deals with enabling machines to comprehend and interpret human language. NLP-based systems have been instrumental in powering a wide range of applications such as Google’s powerful search engine and more recently, Amazon’s voice assistant, Alexa. In addition, NLP has proved useful in teaching machines how to carry out complex natural language-related tasks such as dialogue generation and machine translation. With the explosive growth in digital data, organizations have increasingly relied on NLP as an essential tool to extract insights from text data.
Deep Learning models have revolutionized NLP in recent years, offering high levels of accuracy and efficiency in processing natural language. Keep reading to uncover more about this amazing topic.
What is Deep Learning?
Deep Learning, a machine learning subset, focuses on developing algorithms and models that can improve and learn through the experience without needing reprogramming. The models employ artificial neural networks that imitate the human brain’s structure and function, allowing them to learn intricate data representations. Consequently, deep Learning models have found extensive application in processing natural language, leading to a transformative impact on the AI industry.

- Recurrent Neural Networks (RNNs)
Recurrent Neural Networks, commonly known as RNNs, are a fascinating branch of neural-based approaches that excel at handling sequential data. The concept of RNNs lies in their ability to recursively apply computation to each element of a given input sequence while taking into account the previously computed results. This means that RNNs have the power to memorize the outcomes of previous computations and use them to guide the current computation.
In the field of NLP, RNNs have proven to be quite handy for a variety of tasks such as language modeling, text classification, and machine translation. One of the significant advantages of RNNs is their ability to process variable-length input sequences, making them an excellent fit for handling natural language, which is inherently diverse and variable. With RNNs, one can efficiently process complex sentences, paragraphs, and even entire documents to extract meaningful information.
- Recursive Neural Network
Similar to RNNs, recursive neural networks are a powerful tool for modeling sequential data. The deep, tree-like structure of Recursive Neural Networks enables them to handle hierarchical data by combining child nodes to produce parent nodes. This is akin to the nature of language which can be viewed as a recursive structure, with words and sub-phrases building up into higher-level phrases in a hierarchical fashion. This unique ability makes recursive neural networks particularly useful in the sentiment analysis of natural language sentences. By leveraging the complexity and variations inherent in language, these networks can deliver accurate predictions with a low level of predictability. So, if you’re looking for a tool that can handle complex, multi-level data and provide unexpected insights, a Recursive Neural Network may be just what you need.
- Convolutional Neural Networks (CNNs)
Convolutional Neural Networks (CNNs) belong to a family of neural networks that specialize in the processing of spatial data, such as images. Essentially, a CNN is a neural-based approach that employs a feature function to extract higher-level features from constituent words or n-grams. In the realm of NLP, CNNs are frequently employed for tasks like text classification and sentiment analysis. Though initially designed for image processing, CNNs have been repurposed to handle text data by treating words as spatial entities. This innovation has extended the applicability of CNNs beyond their original purpose.
- Transformer Neural Network
The Transformer Neural Network is an innovative architecture developed to solve sequence-to-sequence tasks while easily handling long-range dependencies. It was first proposed in the paper “Attention Is All You Need” and is now has gained increasing popularity in the field of NLP due to its high accuracy and efficiency.
