Sequence to Sequence Framework in PyTorch

nmtpytorch Sequence to Sequence Framework in PyTorch This project is not actively maintained so issues created are unlikely to be addressed in a timely way. If you are interested, there’s a recent fork of this repository called pysimt which includes Transformer-based architectures as well. nmtpytorch allows training of various end-to-end neural architectures includingbut not limited to neural machine translation, image captioning and automaticspeech recognition systems. The initial codebase was in Theano and wasinspired from the famous dl4mt-tutorialcodebase. nmtpytorch received valuable […]

Pytorch implementation of Tacotron

Tacotron-pytorch A pytorch implementation of Tacotron: A Fully End-to-End Text-To-Speech Synthesis Model. Data I used LJSpeech dataset which consists of pairs of text script and wav files. The complete dataset (13,100 pairs) can be downloaded here. I referred https://github.com/keithito/tacotron for the preprocessing code. File description hyperparams.py includes all hyper parameters that are needed. data.py loads training data and preprocess text to index and wav files to spectrogram. Preprocessing codes for text is in text/ directory. module.py contains all methods, including […]

Learning General Purpose Distributed Sentence Representations via Large Scale Multi-task Learning

Learning General Purpose Distributed Sentence Representations via Large Scale Multi-task Learning Sandeep Subramanian, Adam Trischler, Yoshua Bengio & Christopher Pal ICLR 2018 About GenSen is a technique to learn general purpose, fixed-length representations of sentences via multi-task training. These representations are useful for transfer and low-resource learning. For details please refer to our ICLR paper. Code We provide a PyTorch implementation of our paper along with pre-trained models as well as code to evaluate these models on a variety of […]

Identifying The Language of A Document Using NLP!

This article was published as a part of the Data Science Blogathon Introduction The goal of this article is to identify the language from the written text. The text in documents is available in many languages and when we don’t know the language it becomes very difficult sometimes to tell this to google translator as well. For most translators, we have to tell both the input language and the desired language. If you had a text written in Spanish and you […]

NumPy views: saving memory, leaking memory, and subtle bugs

If you’re using Python’s NumPy library, it’s usually because you’re processing large arrays that use plenty of memory. To reduce your memory usage, chances are you want to minimize unnecessary copying, NumPy has a built-in feature that does this transparently, in many common cases: memory views. However, this feature can also cause higher memory usage by preventing arrays from being garbage collected. And in some cases it can cause bugs, with data being mutated in unexpected ways. To avoid these […]
