A Gentle Introduction to Machine Learning Modeling Pipelines

Applied machine learning is typically focused on finding a single model that performs well or best on a given dataset. Effective use of the model will require appropriate preparation of the input data and hyperparameter tuning of the model. Collectively, the linear sequence of steps required to prepare the data, tune the model, and transform the predictions is called the modeling pipeline. Modern machine learning libraries like the scikit-learn Python library allow this sequence of steps to be defined and […]

Microsoft DeBERTa surpasses human performance on the SuperGLUE benchmark

Natural language understanding (NLU) is one of the longest running goals in AI, and SuperGLUE is currently among the most challenging benchmarks for evaluating NLU models. The benchmark consists of a wide range of NLU tasks, including question answering, natural language inference, co-reference resolution, word sense disambiguation, and others. Take the causal reasoning task (COPA in Figure 1) as an example. Given the premise “the child became immune to the disease” and the question “what’s the cause for this?,” the […]

Python: Safely Create Nested Directory

Introduction File manipulation is one of the most important skills to master in any programming language, and doing it correctly is of utmost importance. Making a mistake could cause an issue in your program, other programs running on the same system, and even the system itself. Possible errors can occur due to the parent directory not existing, or by other programs changing files in the file system at the same time, creating something that is called a race condition. A […]

How to Merge DataFrames in Pandas – merge(), join(), append(), concat() and update()

Introduction Pandas provides a huge range of methods and functions to manipulate data, including merging DataFrames. Merging DataFrames allows you to both create a new DataFrame without modifying the original data source or alter the original data source. If you are familiar with the SQL or a similar type of tabular data, you probably are familiar with the term join, which means combining DataFrames to form a new DataFrame. If you are a beginner it can be hard to fully […]

Best Practices for Data-Efficient Modeling in NLG: How to Train Production-Ready Neural Models with Less Data

December 8, 2020 By: Ankit Arun, Soumya Batra, Vikas Bhardwaj, Ashwini Challa, Pinar Donmez, Peyman Heidari, Hakan Inan, Shashank Jain, Anuj Kumar, Shawn Mei, Karthik Mohan, Michael White Abstract Natural language generation (NLG) is a critical component in conversational systems, owing to its role of formulating a correct and natural text response. Traditionally, NLG components have been deployed using template-based solutions. Although neural network solutions recently developed in the research community have been shown to provide several benefits, deployment of […]

Semi-Supervised Learning With Label Spreading

Semi-supervised learning refers to algorithms that attempt to make use of both labeled and unlabeled training data. Semi-supervised learning algorithms are unlike supervised learning algorithms that are only able to learn from labeled training data. A popular approach to semi-supervised learning is to create a graph that connects examples in the training dataset and propagates known labels through the edges of the graph to label unlabeled examples. An example of this approach to semi-supervised learning is the label spreading algorithm […]

How to Use Global and Nonlocal Variables in Python

Introduction In this article we’ll be taking a look at Global and Non-Local Variables in Python and how you to use them to avoid issues when writing code. We’ll be starting off with a brief primer on variable scopes before we launch into the how and why of using global and non-local variables in your own functions. Scopes in Python Before we can get started, we first have to touch on scopes. For those of you who are less familiar, […]
