The next question is, why do we even bother to explain something that is just a guess (but a very good one). If it works why do we even care? Actually the problem lies in us, in humans. Nowadays we don't trust anything that we cannot understand. The interesting part is that we still have trust in specialist (if it's a human specialist and not a robot), even if the error rate of a human specialist is much higher than of a specialized Artificial Neural Network.

Learn to build a Polynomial Regression model to predict the values for a non-linear dataset. In this article, we will go through the program for building a Polynomial Regression model based on the non-linear data. In the previous examples of Linear Regression, when the data is plotted on the graph, there was a linear relationship between both the dependent and independent variables. Thus, it was more suitable to build a linear model to get accurate predictions. What if the data points had the following non-linearity making the linear model giving an error in predictions due to non-linearity? In this case, we have to build a polynomial relationship which will accurately fit the data points in the given plot.

In previous stories, I have given a brief of Linear Regression and showed how to perform Simple and Multiple Linear Regression. In this article, we will go through the program for building a Polynomial Regression model based on the non-linear data. In the previous examples of Linear Regression, when the data is plotted on the graph, there was a linear relationship between both the dependent and independent variables. Thus, it was more suitable to build a linear model to get accurate predictions.

Last year, we announced Snap ML, a python-based machine learning framework that is designed to be a high-performance machine learning software framework. Snap ML is bundled as part of the WML Community Edition or WML CE (aka PowerAI) software distribution that is available for free on Power systems. The first release of Snap ML enabled GPU-acceleration of generalized linear models (GLMs) and also enabled scaling these models to multiple GPUs and multiple servers. GLMs are popular machine learning algorithms, which include logistic regression, linear regression, ridge and lasso regression, and support vector machines (SVMs). Our previous blog showed that Logistic Regression using Snap ML is 46 times faster than other methods, which rely on CPUs alone.

Explainable AI (XAI) is paramount in industry-grade AI; however existing methods fail to address this necessity, in part due to a lack of standardisation of explainability methods. The purpose of this paper is to offer a perspective on the current state of the area of explainability, and to provide novel definitions for Explainability and Interpretability to begin standardising this area of research. To do so, we provide an overview of the literature on explainability, and of the existing methods that are already implemented. Finally, we offer a tentative taxonomy of the different explainability methods, opening the door to future research.
