Separating Planes In SVM

Updated on 07-Aug-2023 15:24:30


Support Vector Machine (SVM) is a supervised algorithm used widely in handwriting recognition, sentiment analysis and many more. To separate different classes, SVM calculates the optimal hyperplane that more or less accurately creates a margin between the two classes. Here are a few ways to separate hyperplanes in SVM. Data Processing − SVM requires data that is normalised, scaled and centred since they are sensitive to such features. Choose a Kernel − A kernel function is used to transform the input into a higher dimensional space. Some of them include linear, polynomial and radial base functions. Let ... Read More

Semantic Analysis in NLP

Updated on 07-Aug-2023 15:18:44


Natural Language Processing (NLP) requires complex processes such as Semantic Analysis to extract meaning behind texts or audio data. Through algorithms designed for this purpose, we can determine three primary categories of semantic analysis. Types of Semantics Lexical semantics − Lexical analysis examines how particular terms express meanings while accounting for synonyms antonyms as well as homophones Sentence semantics − Sentence-level semantic analysis seeks to decipher how phrases interact with each other in context to understand larger messages conveyed by those statements. Discourse semantics − This is the study of the meaning of a longer text or speech, considering ... Read More

Unsupervised backpropagation in Machine Learning

Jay Singh
Updated on 31-Jul-2023 19:25:33


Artificial intelligence's branch of machine learning gives computers the ability to learn from data and make judgments. A labeled dataset is used to train a model in supervised learning, whereas an unlabeled dataset is used in unsupervised learning. A neural network is used in unsupervised back propagation, a sort of unsupervised learning, to discover patterns in an unlabeled dataset. This blog article will outline unsupervised back propagation before moving on to practical Python code. What is unsupervised back propagation? Back propagation is a supervised learning method that modifies the weights of neural networks to reduce the discrepancy between predicted and ... Read More

TF-IDF in Sentiment Analysis

Jay Singh
Updated on 31-Jul-2023 19:21:03


In order to recognize and classify emotions conveyed in a text, such as social media postings or product evaluations, sentiment analysis, a natural language processing approach, is essential. Businesses can enhance their offers and make data-driven decisions by using this capability to discover client attitudes towards their goods or services. A popular technique in sentiment analysis is called Term Frequency-Inverse Document Frequency (TF-IDF). It determines the significance of words inside a text in relation to the corpus as a whole, assisting in the identification of important phrases that express positive or negative moods. Algorithms for sentiment analysis can precisely categorize ... Read More
