Description

According to industry estimates, more than 80% of the data being generated is in an unstructured format, maybe in the form of text, image, audio, video, etc. Data is generated as we speak, write, tweet, use social media, send messages, use ecommerce, and in various other activities. Textual data is the most common, and more than 50% of the data exists in this form. A lot of insights can be mined from this huge repository of unstructured datasets, but it needs a sophisticated approach.

In order to produce significant and actionable insights from text data, it’s necessary to make use of natural language processing (NLP) coupled with machine learning, deep learning, and state-of-the-art techniques in this space. With the latest developments and improvements in the field of deep learning and artificial intelligence, many demanding natural language processing tasks become easy to implement and execute. Text generation is one of the tasks that can be built using deep learning models, especially recurrent neural networks and its variant, long short-term memories (LSTMs).

Text generation is a language modeling problem. Language modeling is at the heart of many natural language processing tasks, such as speech synthesis, session systems, and text synthesis. A well-trained language model learns the probability of a word appearing based on a sequence of previous words used in the text. Language models can be used at the level of characters, n-grams, sentences, and even paragraphs.

Vijay Srinivas Agneeswaran, Pramod Singh, and Akshay Kulkarni explore how to create a language model that generates natural language text by implementing and forming a recurrent neural network and attention networks built on top of TensorFlow 2.0. They also examine how to efficiently build and use NLP-based applications for text summarization using deep learning networks on TensorFlow 2.0. Text summarization require great deal of abstraction, so they use sequence-to-sequence models and bidirectional encoder and decoders.

Not only do you get to see the notebooks for the problems outlined above but also how some of text analytics can be implemented on top of Kubeflow, which helps build scalable productionizable implementations.
