The Impact of Generative AI on Data EngineeringData Science by Sunny Srinidhi - March 9, 2025March 9, 20250 Generative AI is transforming the field of data engineering by automating complex processes such as data augmentation, cleaning, integration, and anomaly detection. Unlike traditional AI, which focuses on analysis and prediction, Generative AI creates new data based on learned patterns. This capability improves data quality, enhances efficiency, and enables scalable solutions. However, challenges like data privacy, model bias, and ethical concerns must be carefully managed. As AI technology advances, its role in data engineering will continue to expand, leading to more intelligent and automated data workflows.

Lemmatization in Natural Language Processing (NLP) and Machine LearningData Science by Sunny Srinidhi - February 26, 2020February 26, 20200 Lemmatization is one of the most common text pre-processing techniques used in Natural Language Processing (NLP) and machine learning in general. If you've already read my post about stemming of words in NLP, you'll already know that lemmatization is not that much different. Both in stemming and in lemmatization, we try to reduce a given word to its root word. The root word is called a stem in the stemming process, and it is called a lemma in the lemmatization process. But there are a few more differences to the two than that. Let's see what those are. How is Lemmatization different from Stemming In stemming, a part of the word is just chopped off at the tail end to arrive at
Removing stop words in Java as part of data cleaning in Artificial IntelligenceData Science by Sunny Srinidhi - February 5, 2020February 5, 20200 More in The fastText Series. Working with text datasets is very common in data science problems. A good example of this is sentiment analysis, where you get social network posts as data sets. Based on the content of these posts, you need to estimate the sentiment around a topic of interest. When we're working with text as the data, there are a lot of words which we want to remove from the data to "clean" it, such as normalising, removing stop words, stemming, lemmatizing, etc. In this post, we'll see how we can remove stop words from our input text to clean our data so that our analysis is based only on the actual content of the data. But wait, what are stop
Optimising a fastText model for better accuracyData Science by Sunny Srinidhi - December 3, 2019December 19, 20190 More in The fastText Series. In our previous post, we saw what n-grams are and how they are useful. Before that post, we built a simple text classifier using Facebook’s fastText library. In this post, we’ll see how we can optimise that model for better accuracy. Precision and Recall Precision and recall are two things we need to know to better understand the accuracy of our models. And these two things are not very difficult to understand. Precision is the number of correct labels that were predicted by the fastText model, and recall is the number of labels, out of the correct labels, that were successfully predicted. That might be a bit confusing, so let’s look at an example to understand it better. Suppose for a sentence
Understanding Word N-grams and N-gram Probability in Natural Language ProcessingData Science by Sunny Srinidhi - November 26, 2019December 19, 20192 More in The fastText Series. N-gram is probably the easiest concept to understand in the whole machine learning space, I guess. An N-gram means a sequence of N words. So for example, “Medium blog” is a 2-gram (a bigram), “A Medium blog post” is a 4-gram, and “Write on Medium” is a 3-gram (trigram). Well, that wasn’t very interesting or exciting. True, but we still have to look at the probability used with n-grams, which is quite interesting. Why N-gram though? Before we move on to the probability stuff, let’s answer this question first. Why is it that we need to learn n-gram and the related probability? Well, in Natural Language Processing, or NLP for short, n-grams are used for a variety of things.
An intro to text classification with Facebook’s fastText (Natural Language Processing)Data Science by Sunny Srinidhi - November 25, 2019December 19, 20193 More in The fastText Series. Text classification is a pretty common application of machine learning. In such an application, machine learning is used to categorise a piece of text into two or more categories. There are both supervised and unsupervised learning models for text classification. In this post, we’ll see how we can use Facebook’s fastText library for some simple text classification. fastText, developed by Facebook, is a popular library for text classification. The library is an open source project on GitHub, and is pretty active. The library also provides pre-built models for text classification, both supervised and unsupervised. In this post, we’ll check out how we can train the supervised model in the library for some quick text classification. The library
Data Science vs. Artificial Intelligence vs. Machine Learning vs. Deep LearningData Science by Sunny Srinidhi - November 18, 2019December 19, 20190 It’s very common these days to come across these terms - data science, artificial intelligence, machine learning, deep learning, neural networks, and much more. But what do these buzzwords actually mean? And why should you care about one or the other? I’m trying to answer these questions in this post, to the best of my capacity. But then again, I’m no expert here. This is the knowledge I’ve gained in the last few years of my data science and machine learning journey. I’m sure most of you will have better and easier ways of explaining things than I do, so I’ll be looking forward to reading your comments down below. Let’s get started then. Data Science Data science is all about data,
Top Five Machine Learning courses for beginners on UdemyData Science by Sunny Srinidhi - November 18, 2019December 19, 20192 Everybody wants to do machine learning these days. Machine learning, data science, artificial intelligence, deep learning, neural network — these have become some of the most used phrases in the tech space today. I’m not saying it’s particularly bad, but it definitely gets scary for somebody who doesn’t really know what all this means but wants to get into the rat race. When you think about it, from a software developer’s point of view, these are just different types of software or applications you work on, but with more math involved. I know I’m oversimplifying what data science is, but for somebody who doesn’t have a mathematics or statistics background, it is very difficult to understand the jargon initially. I’ve been there,
Null Hypothesis and the P-ValueData Science by Sunny Srinidhi - November 8, 2019November 8, 20195 When you're starting your machine learning journey, you'll come across null hypothesis and the p-value. At a certain point in your journey, it becomes quite important to know what these mean to make meaningful decisions while designing your machine learning models. So in this post, I'll try to explain what these two things mean, and you try to understand that. Now, if you don't have a background in statistics, the definitions of null hypothesis and p-value will make no sense to you. It's just gibberish going way over your head. That's what happened to me the first few times I tried to understand them. It took me a good couple of days to get an idea of what they mean. I
