How to Access Index in Python’s for Loop

Introduction Python is a very high-level programming language, and it tends to stray away from anything remotely resembling internal data structure. Because of this, we usually don’t really need indices of a list to access its elements, however, sometimes we desperately need them. In this article, we will go over different approaches on how to access an index in Python’s for loop. How to Access Index in Python’s for Loop? The easiest, and most popular method to access the index […]

Comparing Datetimes in Python – With and Without Timezones

Introduction When working with dates, oftentimes, you’d like to know if a given date comes before or after another date. We can get these answers by comparing dates. In this article, we will learn how to use the Python datetime module to create and compare both naive (without timezone info) and aware (with timezone info) dates. To compare the dates, we will use the comparison operators in Python: , ==, =, !=. Note: The datetime module has two methods for […]

Introduction to Automatic Speech Recognition and Natural Language Processing

This article was published as a part of the Data Science Blogathon. Introduction In this article, we will take a closer look at how speech recognition really works. Now, when we say speech recognition, we’re really talking about ASR, or automatic speech recognition. With automatic speech recognition, the goal is to simply input any continuous audio speech and output the text equivalent. We want our ASR to be speaker-independent and have high accuracy. Such a system has long been a […]

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 […]
