"Hello, World" of Machine Learning
Say hello to the "Hello, World" of machine learning 1. Before you begin In this , you'll learn the basic "Hello, World" of ML, where instead of programming explicit rules in a language, such as Java or C++, you'll build a system trained on data to infer the rules that determine a relationship between numbers. Consider the following problem: You're building a system that performs activity recognition for fitness tracking. You might have access to the speed at which a person is walking and attempt to infer their activity based on that speed using a conditional. if ( speed < 4 ){ status = WALKING ; } You could extend that to running with another condition. if ( speed < 4 ){ status = WALKING ; } You could extend that to running with another condition. if ( speed < 4 ){ status = WALKING ; } else { status = RUNNING ; } In a final condition, you could similarly detect cycling. if ( speed < 4 ){ status = WALKING ; } else if ( sp
