What is the principle of conservation of energy? In physics, the term conservation refers to something which doesn t change This means that the variable in an equation which represents a conserved quantity is constant over time It has the same value both before and after an event...

How A Ball Screw Works A The Ball Screw Assembly The ball screw assembly consists of a screw and a nut, each with matching helical grooves, and balls which roll between these grooves providing the only contact between the nut and the screw As the screw or nut rotates, the balls are deflected by the deflector into the ball return system of the nut and they travel through the ,...

31 Importance of Interpretability If a machine learning model performs well, why do we not just trust the model and ignore why it made a certain decision? The problem is that a single metric, such as classification accuracy, is an incomplete description of most real-world tasks Doshi-Velez and Kim 2017 6 Let us dive deeper into the reasons why interpretability is so important...
