In this post, you will discover the confusion matrix for use in machine learning. After reading this post you will know: What the confusion matrix is and why you need to use it. How to calculate a confusion matrix for a 2-class classification problem from scratch. How create a confusion ...
This was the time when everyone started hearing about TFT LCDs or “active matrix LCDs.” TFT simply stands for Thin Film Transistor and a TFT LCD is simply another variation of an LCD display. They were all the buzz when they were released because they boasted great color, contrast and re...
This is morally equivalent to the graph being a Lagrangian submanifold of (where we give the second copy of phase space the negative of the usual symplectic form , thus yielding as the full symplectic form on ; this is another instantiation of the closed graph theorem, as mentioned in this ...
For GUE, which is a continuous matrix ensemble, one can also define for distinct as the unique quantity such that the probability that there is an eigenvalue in each of the intervals is in the limit . As is well known, the GUE process is a determinantal point process, which means that ...
Such an artifact topology is generated by inverting a fixed model, and as such, the model enters the second path illus- trated in Fig. 1: design by inversion. The authors explained that the model considered in a GDA is often noninvertible, which, as we have seen above, leads to the...
(double-inversion recovery axial image recovery, or DIR), thereby effectively inverting only the tissue and blood outside the imaging slice (Fig.1a). The inversion time (TI) between the inversion pulses and imaging readout is chosen such that blood longitudinal magnetization is nulled (as a ...

, derived inWhat Is a Block Matrix?). So For the general case write . Inverting this equation and applying the previous result gives subject to the nonsingularity condition . This is known as the Sherman–Morrison formula. It explicitly identifies the rank- ...
Chapter 1, Creating a Game Window, explains how to create a new visual studio project, create a Win32 window, set up an OpenGL 3.3 render context, and enable vsynch. The code samples for this book are compiled against OpenGL 3.3. All the OpenGL code is compatible with the latest version...
What is the principle of the transistor? What are some analogs between liquid and circuits? What type of feedback must be given to a Hartley oscillator? What is the difference between the inverting and noninverting amplifiers? How many gates are required in a full adder circuit?
