Use cases of Tensor2Tensor The Tensor2Tensor library has various data types and uses cases that can be used easily for complex tasks and modelling. So let us look into some of the standard functionalities and use cases of the Tensor2Tensor library. Mathematical Language understanding For mathematical language, understanding respect to mathematical attributes to perform various mathematical operations is made easy by the Tensor2Tensor library. So for mathematical model understanding, the library provides us with a readily available dataset known as the MLU dataset under the problems functionality. For this problem statement, there are 3 types of transformers that are pretrained for mathematical language understanding, which uses different sets of transformers and hyperparameters for the respective models. Question Answering The Tensor2Tensor library consists of a pretrained dataset known as the “BABI” dataset, where the data characteristics are similar to question answering from a story. There are various sets of question answering sets and subsets in the data, and this can be used accordingly for developing and evaluating the Question Answering models. Image Classification The Tensor2Tensor library consists of various datasets suitable for image classification, such as ImageNet, CIFAR, and MNIST. So the datasets can be made available using appropriate problem constraints and used accordingly to accelerate and increase the availability of image classification models and tasks. For ImageNet data, some of the transfer learning models like ResNet and Xception are trained and made available in the form of a model, and the parameters of the model can be used accordingly with the appropriate set of parameters to instantiate the model training on the platform. For CIFAR and MNIST, a pre-trained regularisation technique named shake-shake regularization is being used to improve image classification. So the data can be made available, and the suitable parameters have to be declared accordingly to extract the data and the model trained accordingly for image classification. Image Generation The Tensor2Tensor library has various standard datasets for image generation, such as CeleBA, CIFAR10, MS-COCO, and many more, which can be used extensively for image generation with the required set of parameters and constraints. So the deep learning model, which is made available in the library, can be pulled into the working environment and used for image generation tasks accordingly. Language Modeling The Tensor2Tensor library can be used for easy language modelling and translation. Various language data and language models are made available in the form of problems (data) and models, and this can be suitably pulled into the working environment and used accordingly for language modelling and language translation tasks. Sentiment Analysis For sentiment analysis, the Tensor2Tensor library consists of the IMDB data for recognizing the sentiment of a sentence, and the library provides a trained model to perform sentiment analysis on a text sentence. So the model and the parameters for sentiment analysis from the library have to be pulled into the working environment, and the readily available trained model can be used accordingly to perform sentiment analysis. Speech Recognition The Tensor2Tensor library can be used for speech recognition as the library has two inbuilt datasets for speech recognition. They are basically Speech to text data where the speech is generally in the English language. The datasets available in the library are Librispeech, and Mozilla Common Voice, where the data has to be pulled into the working environment according to the standard problem constraint, and the models trained respectively on each of the data have to be pulled in a similar manner into the working environment with an appropriate model trained with respect to the data.
