Generative Learning refers to a special class of statistical models that are capable ofgenerating content that is very hard to distinguish from the reality (or fake content thatlooks real). The generated content could be poems, images, music, songs, videos, 3Dobjects or content from some other domain we could imagine. A domain is nothing but a fancy word for… Read More »
Generative Learning and its Differences from the Discriminative Learning Generative Learning refers to a special class of statistical models that are capable ofgenerating content that is very hard to distinguish from the reality (or fake content thatlooks real). The generated content could be poems, images, music, songs, videos, 3Dobjects or content from some other domain we could imagine.… Read More »
This article focuses on giving the readers some basic understanding of the Variational Autoencoders and explaining how they are different from the ordinary autoencoders in Machine Learning and Artificial Intelligence. Unlike vanilla autoencoders(like-sparse autoencoders, de-noising autoencoders ..etc), Variational Autoencoders (VAEs) are generative models like GANs (Generative Adversarial Networks). This article is primarily focused on the Variational Autoencoders and… Read More »
Autoencoders are unsupervised Deep Learning techniques that are extensively used for dimensionality reduction, latent feature learning (Learning Representations), and also as generative models (Generative Adversarial Networks: GANs). Denoising Autoencoders are slight modifications to the vanilla autoencoders that can be used for reducing noise from real-world noisy datasets. In this tutorial, we will investigate Convolutional Denoising Autoencoders to reduce… Read More »
We all are well aware of the Supervised Machine Learning algorithms where ML algorithm tries to understand the relationship between input features and labels from the training data and is expected to automatically generate a similar kind of relationship between test data features and set of possible output labels. Although we solve lots of problems with supervised learning… Read More »
Sentiment classification is a common task in Natural Language Processing(NLP). There are various ways to do sentiment classification in Machine Learning (ML). In this article, we talk about how to perform sentiment classification with Deep Learning (Artificial Neural Networks). In my previous two articles, We have already talked about how to perform sentiment analysis using different traditional machine… Read More »
In my previous article on ‘Sentiment Analysis with Python: Bag of Words‘, We compared the results of three traditional machine learning sentiment classification algorithms using bag-of-words features(from scratch). This is my second article on sentiment analysis in continuation of that and this time we are going to experiment with TFIDF features for the task of Sentiment Analysis on… Read More »
Sentiment Analysis Overview Sentiment Analysis(also known as opinion mining or emotion AI) is a common task in NLP (Natural Language Processing). It involves identifying or quantifying sentiments of a given sentence, paragraph, or document that is filled with textual data. Sentiment Analysis techniques are widely applied to customer feedback data (ie., reviews, survey responses, social media posts). Sentiment Analysis has proved… Read More »
Overview Training a Deep Learning model (or any machine learning model in fact) is all about bringing the model predictions (model output) close to the real output(Ground truth) for a given set of input-output pairs. Once the model’s results are close to the real results our job is done. To understand how close model predictions are with respect… Read More »
Handwriting Recognition also termed as HTR(Handwritten Text Recognition) is a machine learning method that aims at giving the machines an ability to read human handwriting from real-world documents(images). The traditional Optical Character Recognition systems(OCR systems) are trained to understand the variations and font-styles in the machine-printed text(from documents/images) and they work really well in practice(example-Tesseract). Handwriting Recognition on… Read More »
