Introduction Handwritten Digit Recognition is a part of image recognition widely used in Computer Vision in Deep learning. Image recognition is one of the very basic and preliminary stages of every image or video−related task in Deep Learning. This article lets an overview of Handwritten Digit Recognition and how Image recognition can be extended to multiclass classification. Before going ahead let us understand the difference between Binary and Multiclass image classification Binary Image Classification In Binary image classification, the model has two classes to predict from. For example in the classification of cats and dogs. Multiclass Image Classification In Multiclass ... Read More

Introduction GrowNet is a novel gradient-boosting framework that uses gradient-boosting techniques to build complex neural networks from shallow deep neural networks. The shallow deep neural networks are used as weak learners. GrowNets today are finding applications in diverse domains and fields. A Brief Refresher of Gradient Boosting Algorithms. Gradient Boosting is the technique to build models sequentially and these models try to reduce the error produced by the previous models. This is done by building a model on the residuals or errors produced by the previous model. It can estimate a function using optimization using numerical methods. The most common ... Read More

Neural networks and deep learning systems are useful for a number of tasks, including pattern recognition and classification. These methods can be used to analyze large and complex datasets, and can often achieve high levels of accuracy in tasks that are difficult for traditional algorithms to solve. Additionally, neural networks and deep learning systems are able to learn and improve over time, which makes them particularly well−suited for tasks that involve unstructured or unlabeled data. In this article, we'll examine neural networks and deep learning systems in-depth and discuss how they vary from one another. What is Neural Network? A ... Read More

In natural language processing, the interlingua and transfer techniques are employed to facilitate language translation and other language-related activities. These techniques are valuable because they enable automatic text translation from one language to another, which may be beneficial in a number of scenarios such as international communication or the processing of vast volumes of multilingual text data. In this post, we will examine and contrast the Interlingua Approach with the Transfer Approach. What is the Interlingua Approach? The interlingua approach is a method for translating text from one language to another in natural language processing. Its foundation is the idea ... Read More

Machine learning projects employ machine learning algorithms and techniques to create models that can make predictions or judgments based on input data. These projects frequently include building a machine learning model on a big dataset, followed by utilizing the taught model to make predictions or choices on fresh, previously unknown data. Machine learning projects can be classified into three types: supervised learning, unsupervised learning, and reinforcement learning. The model is trained on labeled data in supervised learning, and the proper output is delivered for each example in the training set. In unsupervised learning, the model is not given with labeled ...

Welch's ANOVA, is an expansion of the standard ANOVA test that allows for different sample sizes and variances. Frequently, the samples that are being compared in an ANOVA test may not have comparable variances or sample sizes. In certain situations, Welch's ANOVA should be performed rather than the standard ANOVA test since it can not be acceptable. In this post, we'll take a detailed look at Welch's ANOVA What is Welch’s ANOVA? Welch's ANOVA is a variant of the ANOVA test, which is used to compare the means of two or more samples. ANOVA determines if the means of two ... Read More

ANCOVA (analysis of covariance) is a useful statistical method because it enables the inclusion of covariates in the analysis, which may assist adjust for auxiliary variables and increase the precision of group comparisons. These additional factors, or covariates, may be incorporated into the study using ANCOVA. In order to be sure that any observed differences between the groups are caused by the therapy or intervention under study and not by unrelated factors, ANCOVA can be used to adjust for the impact of the covariates on the group means. This can make the comparisons between the groups more accurate and give ... Read More

Obtaining a p−value from a z−score is a typical statistical procedure. The number of standard deviations a value is from the mean of a normal distribution is expressed as a z−score, sometimes referred to as a standard score. The z-score can be used to assess the probability that a specific value will appear in a normal distribution. The probability of getting a test statistic at least as severe as the one that was observed is the p-value, assuming that the null hypothesis is true. Because the z−score is typically the test statistic, determining the p-value from the z−score allows one ... Read More

Studentized residuals are typically used in regression analysis to identify potential outliers in the data. An outlier is a point that is significantly different from the overall trend of the data, and it can have a significant influence on the fitted model. By identifying and analyzing outliers, you can better understand the underlying patterns in your data and improve the accuracy of your model. In this post, we will be closely looking at Studentized Residuals and how you can implement it in python. What are Studentized Residuals? The term "studentized residuals" refers to a particular class of residuals that have ... Read More

Dunn's test is a statistical technique for comparing the means of several samples. When it's required to compare the means of numerous samples to identify which ones are noticeably different from one another, Dunn's test is frequently employed in a range of disciplines, including biology, psychology, and education. We shall examine Dunn's test in−depth in this article, along with a python implementation. What is Dunn’s Test? Dunn's test is a statistical analysis used to compare the means of numerous samples. It is a form of multiple comparison test used to compare the means of more than two samples to identify ... Read More
