Recent Advances in Language Model Fine-tuning

Fine-tuning a pre-trained language model (LM) has become the de facto standard for doing transfer learning in natural language processing. Over the last three years (Ruder, 2018), fine-tuning (Howard & Ruder, 2018) has superseded the use of feature extraction of pre-trained embeddings (Peters et al., 2018) while pre-trained language models are favoured over models trained on translation (McCann et al., 2018), natural language inference (Conneau et al., 2017), and other tasks due to their increased sample efficiency and performance (Zhang […]

HEXA: Self-supervised pretraining with hard examples improves visual representations

Humans perceive the world through observing a large number of visual scenes around us and then effectively generalizing—in other words, interpreting and identifying scenes they haven’t encountered before—without heavily relying on labeled annotations for every single scene. One of the core aspirations in artificial intelligence is to develop algorithms and techniques that endow computers with a strong generalization ability to learn only from raw pixel data to make sense of the visual world, which aligns more closely with how humans […]

Issue #119 – Machine Translationese: Effects of Algorithmic Bias on Linguistic Complexity in MT

25 Feb21 Issue #119 – Machine Translationese: Effects of Algorithmic Bias on Linguistic Complexity in MT This week we have a guest post from Eva Vanmassenhove, Assistant Professor at Tilburg University, Dimitar Shterionov, Assistant Professor at Tilburg University, and Matt Gwilliam, from the University of Maryland. In Translation Studies, it is common to refer to a term called “translationese” that encapsulates a set of linguistic features commonly present in human translations as opposed to originally written texts. Researchers in the […]

AAAI 2021: Accelerating the impact of artificial intelligence

The purpose of the Association for the Advancement of Artificial Intelligence, according to its bylaws, is twofold. The first is to promote research in the area of AI, and the second is to promote the responsible use of these types of technology. The result was a 35th AAAI Conference on Artificial Intelligence (AAAI-21) schedule that broadens the possibilities of AI and is heavily reflective of a pivotal time in AI research when experts are asking bigger questions about how best to responsibly develop, deploy, and integrate the technology. Microsoft and its researchers have been pursuing

Prediction Intervals for Deep Learning Neural Networks

Prediction intervals provide a measure of uncertainty for predictions on regression problems. For example, a 95% prediction interval indicates that 95 out of 100 times, the true value will fall between the lower and upper values of the range. This is different from a simple point prediction that might represent the center of the uncertainty interval. There are no standard techniques for calculating a prediction interval for deep learning neural networks on regression predictive modeling problems. Nevertheless, a quick and […]

Sensitivity Analysis of Dataset Size vs. Model Performance

Machine learning model performance often improves with dataset size for predictive modeling. This depends on the specific datasets and on the choice of model, although it often means that using more data can result in better performance and that discoveries made using smaller datasets to estimate model performance often scale to using larger datasets. The problem is the relationship is unknown for a given dataset and model, and may not exist for some datasets and models. Additionally, if such a […]

Guide to Flask-MongoEngine in Python

Introduction Building a web app almost always means dealing with data from a database. There are various databases to choose from, depending on your preference. In this guide, we shall be taking a look at how to integrate one of the most popular NoSQL databases – MongoDB – with the Flask micro-framework. In this guide, we’ll be exploring how to integrate MongoDB with Flask using a popular library – MongoEngine, and more specifically, its wrapper – Flask-MongoEngine. Alternatively, you can […]

Online Versus Offline NMT Quality: An In-depth Analysis on English–German and German–English

December 8, 2020 By: Maha Elbayad, Michael Ustaszewski, Emmanuelle Esperança-Rodier, Francis Brunet Manquat, Jakob Verbeek, Laurent Besacier Abstract We conduct in this work an evaluation study comparing offline and online neural machine translation architectures. Two sequence-to-sequence models: convolutional Pervasive Attention (Elbayad et al., 2018) and attention-based Transformer (Vaswani et al., 2017) are considered. We investigate, for both architectures, the impact of online decoding constraints on the translation quality through a carefully designed human evaluation on English-German and German-English language pairs, […]

Sentiment Analysis: VADER or TextBlob?

This article was published as a part of the Data Science Blogathon. What Is Sentiment Analysis? Conclusions are integral to practically all human exercises and are key influencers of our practices. Our convictions and impression of the real world, and the decisions we make, are, to an impressive degree, molded upon how others see and assess the world. Therefore, when we have to settle on a choice, we regularly search out the assessments of others. Opinions and their related concepts […]
