Machine Learning or Deep Learning model must be in balanced state

Machine Learning or Deep Learning model must be in balanced state   If you ever built a supervised Machine Learning model on some real-time data, it is impossible that it will perform well both on train set and test set in a first evaluation attempt. Real-time data is so noisy, of course as part of model building activity you might have performed enough cleanup and did efficient feature engineering, though usually the model either will tend to overfit or underfit the training data.   How do you detect if the model is underfit (Bias Problem) or overfit (Variance Problem)? Usually…

Maxima vs Minima and Global vs Local in Machine learning

Maxima vs Minima and Global vs Local in Machine learning

Maxima vs Minima and Global vs Local in Machine learning   You might have heard or read the statement that goes something like “The algorithm might get stuck at one of the local minima and not converge to the global minimum”. But what exactly does it mean? I’ll explain the concept of maxima, minima, local and global. Additionally I’ll be covering how calculus makes it possible to identify these points. I’ll explain the concepts for functions of single variable because they are easy to visualize. However, they extend to multivariate cases. Let us start with a few definitions.   Global Maximum:…

Loss Functions in Machine Learning

Loss Functions in Machine Learning

Loss Functions in Machine Learning In this article we will learn the Loss Functions, types and its applications. Loss function is very simple, which is used to evaluate how well our algorithm works.if our predictions are totally deviate too much from the actual values the loss function would large number and vice versa. By using an optimization function the loss function learns to reduce the error in our prediction values. Generally In machine learning models, we are going to predict a value given a set of inputs. The model has a set of weights and biases that you can tune…

Emoji8 app: Rate your facial expressions against emojis

Emoji8 app: Rate your facial expressions against emojis

Emoji8 app: Rate your facial expressions against emojis Want to know how much your expression is in place? Microsoft recently released the latest Emoji8 app, which allows you to get accurate expression scores. The Emoji8 app is a super fun Windows app that provides emoticons for users to imitate, interpreting and inputting accuracy percentages and scores by analyzing video input from a webcam in real time. What’s more interesting is that users can also directly share the GIF of the expression to the social networking site. Microsoft project manager Killian McCoy said in a blog post that Emoji8 uses “Windows…

Peppers Can Be Plucked By the Robots

Peppers Can Be Plucked By the Robots

Peppers Can Be Plucked By the Robots Gathering vegetables in hot, damp nurseries is a troublesome, awkward and dull work to do. This clarifies the developing number of homestead laborers willing to pick vegetables, for example, peppers. Today, numerous administrators are hoping to defeat this issue and decrease costs via mechanizing work. Some gadgets have been produced, for example, pepper-picking robots, yet they are not yet prepared for commercialization. Subsidized by the EU, the SWEEPER venture looks to connect this hole among research center and market by tackling the issues looked by the Eu and flow models of robot-gatherers. The…
