Pandas is a Python library that is used for data analysis and manipulation. It provides a number of functions for cleaning and formatting data. In this article, we will learn how to clean string data in a given Pandas DataFrame. We will cover the following topics: Removing leading and trailing spaces Replacing special characters Converting to lowercase Removing duplicate values Splitting strings into columns Merging columns Validating data Removing Leading and Trailing Spaces The strip() method can be used to remove leading and trailing spaces from a string. For example, the following code will remove the leading ... Read More

Clustering is a fundamental unsupervised learning technique that aims to discover patterns or groupings in unlabeled data. It plays a crucial role in various domains such as data mining, pattern recognition, and customer segmentation. However, once clustering algorithms are applied, it becomes essential to evaluate their performance and assess the quality of the resulting clusters. Clustering performance evaluation is a critical step in understanding the effectiveness and reliability of clustering algorithms. It involves quantifying the quality of the obtained clusters and providing insights into their consistency and separability. By evaluating clustering results, practitioners can make informed decisions about algorithm selection, ... Read More

Any dataset used in Machine Learning algorithms may have a number of dimensions. However, not all of them contribute to giving an efficient output and simply cause the ML Model to perform poorly because of the increased size and complexity. Thus, it becomes important to eliminate such features from the dataset. To do this, we use a dimension reduction algorithm called PCA. PCA or Principal Component Analysis helps in removing those dimensions from the dataset that do not help in optimizing the results; thereby creating a smaller and simpler dataset with most of the original and useful information. PCA is ... Read More

Support Vector Machines (SVMs) are supervised learning algorithms that can be used for both classification and regression tasks. SVMs are powerful algorithms that can be used to solve a variety of problems. They are particularly well−suited for problems where the data is linearly separable. However, SVMs can also be used to solve problems where the data is not linearly separable by using a kernel trick. In this article, we will explore the theory behind SVMs and demonstrate how to implement them for data classification in Python. We will provide a detailed explanation of the code, and its output, and discuss ... Read More

Naive Bayes algorithm is a powerful tool that one can use to classify the words of a document or text in different categories. As an example, if a document has words like ‘humid’, ‘rainy’, or ‘cloudy’, then we can use the Bayes algorithm to check if this document falls in the category of a ‘sunny day’ or a ‘rainy day’. Note that the Naive Bayes algorithm works on the assumption that the words of the two documents under comparison are independent of each other. However, given the nuances of language, it is rarely true. This is why the algorithm’s ... Read More

Using NMT or Neural Machine Translation in NLP, we can translate a text from a given language to a target language. To evaluate how well the translation is performed, we use the BLEU or Bilingual Evaluation Understudy score in Python. The BLEU Score works by comparing machine translated sentences to human translated sentences, both in n-grams. Also, with the increase in sentence length, the BLEU score decreases. In general, a BLEU score is in the range from 0 to 1 and a higher value indicates a better quality. However, achieving a perfect score is very rare. Note that the ... Read More
