Understanding Espresso Dose Yield

Now that you have fixed your dose, yield is really easy to understand and manipulate. I've found the best way to understand and communicate yield is as a multiple of the dose (some people prefer %'s, others prefer the ratio).. e.g.: a dose of 20g and a yield of 40g is a multiple of 2; a dose of 18g and a yield of 54g is a multiple of 3. So we don't …

9.1.1: Finite-State Machine Overview

A finite-state machine (FSM) or finite-state automaton (FSA, plural: automata), finite automaton, or simply a state machine, is a mathematical model of computation. It is an abstract machine that can be in exactly one of a finite number of states at any given time. The FSM can change from one state to another in response to some …

Feature Extraction Techniques

If the number of features becomes similar (or even bigger!) than the number of observations stored in a dataset then this can most likely lead to a Machine Learning model suffering from overfitting. In order to avoid this type of problem, it is necessary to apply either regularization or dimensionality reduction techniques (Feature Extraction).
