Note: This article is intended for a general audience to try and elucidate the complicated nature of unfairness in machine learning algorithms.

Supervised machine learning algorithms are inherently discriminatory. They are discriminatory in the sense that they use information embedded in the features of data to separate instances into distinct categories -- indeed, this is their designated purpose in life. This is reflected in the name for these algorithms which are often referred to as discriminative algorithms (splitting data into categories), in contrast to generative algorithms (generating data from a given category). When we use supervised machine learning, this "discrimination" is used as an aid to help us categorize our data into distinct categories within the data distribution, as illustrated below. Whilst this occurs when we apply discriminative algorithms -- such as support vector machines, forms of parametric regression (e.g.


Digital phenotyping and machine learning can help assess severe mental illness

#artificialintelligence

Digital phenotyping approaches that collect and analyze Smartphone-user data on locations, activities, and even feelings - combined with machine learning to recognize patterns and make predictions from the data - have emerged as promising tools for monitoring patients with psychosis spectrum illnesses, according to a report in the September/October issue of Harvard Review of Psychiatry. The journal is published in the Lippincott portfolio by Wolters Kluwer.John Tourous, MD, MBI, of Harvard Medical School and colleagues reviewed available evidence on digital phenotyping and machine learning to improve care for people living with schizophrenia, bipolar disorder, and related illnesses. Digital phenotyping provides a much-needed bridge between patients' symptomatology and the behaviors that can be used to assess and monitor psychiatric disorders." "Digital phenotyping is the use of data from smartphones and wearables collected in situ for capturing a digital expression of human behaviors," according to the authors. Psychiatry researchers think that collecting and analyzing this kind of behavioral information might be useful in understanding how patients with severe mental illness are functioning in everyday life outside of the clinic or lab - in particular, to assess symptoms and predict clinical relapses.


What Is SVM?

#artificialintelligence

Support Vector Machine (SVM) is an approach for classification which uses the concept of separating hyperplane. It was developed in the 1990s. It is a generalization of an intuitive and simple classifier called maximal margin classifier. In order to study Support Vector Machine (SVM), we first need to understand what is maximal margin classifier and support vector classifier. In maximal margin classifier, we use a hyperplane to separate the classes.


Scikit-Optimize for Hyperparameter Tuning in Machine Learning

#artificialintelligence

Hyperparameter optimization refers to performing a search in order to discover the set of specific model configuration arguments that result in the best performance of the model on a specific dataset. There are many ways to perform hyperparameter optimization, although modern methods, such as Bayesian Optimization, are fast and effective. The Scikit-Optimize library is an open-source Python library that provides an implementation of Bayesian Optimization that can be used to tune the hyperparameters of machine learning models from the scikit-Learn Python library. You can easily use the Scikit-Optimize library to tune the models on your next machine learning project. In this tutorial, you will discover how to use the Scikit-Optimize library to use Bayesian Optimization for hyperparameter tuning.

How Does Image Classification Work?

#artificialintelligence

How can your phone determine what an object is just by taking a photo of it? How do social media websites automatically tag people in photos? This is accomplished through AI-powered image recognition and classification. The recognition and classification of images is what enables many of the most impressive accomplishments of artificial intelligence. Yet how do computers learn to detect and classify images?


Different results for support vector machine(SVM) using R

#artificialintelligence

I came up with following issue when I try to extract the predicted probabilities using support vector machine (SVM). Usually the probability cutoff for a classification algorithm is 0.5. But I need to analysis how the accuracy changes with the probability cutoff for SVM machine learning algorithm. So it will only store the predicted class labels. To extract the predicted probabilities, I need to specify classProbs T inside the trainControl.

Support Vector Machines (SVM) and its Python implementation

#artificialintelligence

The support vector machines algorithm is a supervised machine learning algorithm that can be used for both classification and regression. In this article, we will be discussing certain parameters concerning the support vector machines and try to understand this algorithm in detail. For understanding, let us consider the SVM used for classification. The following figure shows the geometrical representation of the SVM classification. After taking a look at the above diagram you might notice that the SVM classifies the data a bit differently as compared to the other algorithms.


[D] Speeding Up SVM by 120X and more!

#artificialintelligence

Support Vector Machines can be a lot slow to run on large datasets. With more data, the speedup increases proportionally which is great for use. Thundersvm also runs with support vector regression and a bunch more stuff. You can check out there github repo here. I have written an article on how to install and use thundersvm.
