Hadoop is effective in dealing with large amounts of structured, unstructured and semi-structured data. Analyzing unstructured data isn't easy, but Hadoop's storage, processing and data collection capabilities
For example, in data science, models like linear or logistic regression will miss something important about the data and end up with prediction bias. It’s like putting blinders on the horses; they only see straight ahead thus accuracy is reduced due to simplified assumptions. 7. What is dime...
61. What are the assumptions of linear regression? To understand the assumptions of linear regression, start with the linearity assumption, which states that the relationship between predictors and the response variable must be linear. Next, ensure that residuals are normally distributed and homoscedasti...
It is a function that decides if a neuron needs activation or not by calculating the weighted sum on it with the bias. Using an activation function makes the model output to be non-linear. There are many types of activation functions: ReLU Softmax Sigmoid Linear Tanh Get 100% Hike!

Answer to: Answer the following True or False questions based on linear regression model. By signing up, you'll get thousands of step-by-step...
The simplest example is the usage of linear regression (y=mt+c) to predict the output of a variable y as a function of time. The machine learning model learns the trends in the dataset by fitting the equation on the dataset and evaluating the best set of values for m and c. One can...
27. The judgmental forecasting methods used to predict the future project performance are based on opinions and probable cost and schedule estimates. Which of the following is NOT an example of a judgmental method? Scenario building Forecast by analogy. Delphi method Linear regression Explanation: n...
44. What are the assumptions you need to take before starting with linear regression? There are primarily 5 assumptions for a Linear Regression model: Multivariate normality No auto-correlation Homoscedasticity Linear relationship No or little multicollinearity ...
This study explores the factors that influence the response quantity for questions on an academic social Q&A platform. Using 130 questions from the library and information services domain on ResearchGate Q&A, we adopt content analysis and multiple linear regression analysis to investigate the relationship...
