K-Means clustering for mixed numeric and categorical data My data set contains a number of numeric attributes and one categorical. Say, NumericAttr1, NumericAttr2, ..., NumericAttrN, CategoricalAttr, where CategoricalAttr takes one of three possible values: CategoricalAttrValue1, CategoricalAttrValue2 or CategoricalAttrValue3. I'm using default . It works with numeric data only. So my question: is it correct to split the categorical attribute CategoricalAttr into three numeric (binary) variables, like IsCategoricalAttrValue1, IsCategoricalAttrValue2, IsCategoricalAttrValue3 ? Do I have 32-bit or 64-bit? How do I copy to the clipboard in JavaScript? Book with a girl whose grandma is a phoenix, cover depicts the emerald/green-eyed blonde girl I read this book in 2016, but I remember the cover being torn up, so it couldn't have been a new book. There was a girl's face on the cover. She had lightly colored skin, and beautiful emerald green eyes. Her hair was a dirty blond. This book was first in a trilogy and the cover was illustrated.  The girl's grandmother in the story was actually a phoenix (I think this was revealed in a different book in the trilogy though). The book started out in a small village, and I can't remember exactly where in the village chapters (the chapters that took place in the village) but she sneaked her deceased mother's green dress out of a trunk she wasn't supposed to go in, and I think she wore it to some event. I understand we cannot state with arbitrary precision the position and momentum of a micro-particle as we superpose infinite waves to create a wave packet at the exact position of the particle and hence cannot say which wave is corresponding to its momentum. This is theoretically said. Also some people say that measurement of one disturbs the other and some say it's reality.  Firstly, the theoretical explanation: why should I consider that a wave out of many superposed will give us the momentum or position? We might use another single wave which is not sine in nature and might get the results. Or why won't a single sine wave suffice? This all considers the micro-particle as wave because of de Broglie.  Secondly, the practical thing seems legit.  Thirdly, the electron must have some kinetic energy and position. It is who we are measuring and can't get it exact so why blame the electron as in theoretical concept. How we quantify the uncertainty, it must depend on the measuring device and various other factors.  I might need to edit this post based on your answer so that I can explain more clearly my thinking.  Edit: From here is what gets the measurement problem:        Text: Imagine that you're blind and over time you've developed a technique for determining how far away an object is by throwing a medicine ball at it. If you throw your medicine ball at a nearby stool, the ball will return quickly, and you'll know that it's close. If you throw the ball at something across the street from you, it'll take longer to return, and you'll know that the object is far away.   The problem i­s that when you throw a ball -- especially a heavy one like a medicine ball -- at something like a stool, the ball will knock the stool across the room and may even have enough momentum to bounce back. You can say where the stool was, but not where it is now. What's more, you could calculate the velocity of the stool after you hit it with the ball, but you have no idea what its velocity was before you hit it.   This is the problem revealed by Heisenberg's Uncertainty Principle. To know the velocity of a quark we must measure it, and to measure it, we are forced to affect it. The same goes for observing an object's position. Uncertainty about an object's position and velocity makes it difficult for a physicist to determine much about the object.   Edit: After seeing this answer one of my doubts is very well cleared, the other answers are also written and helpful:        Text: There is a definine velocity and momentum, we just don't know it.   Nope. There is no definite velocity--this was the older interpretation. The particle has all (possible) velocities at once;it is in a wavefunction, a superposition of all of these states. This can actually be verified by stuff like the double-slit experiment with one photon--we cannot explain single-photon-fringes unless we accept the fact that the photon is in "both slits at once".So, it's not a knowledge limit. The particle really has no definite position/whatever. If $(1), (log_yx), (log_zy), (-15log_xz)$ are in Arithmetic Progression... If $(1), (log_yx), (log_zy), (-15log_xz)$ are in AP then...   (A)$z^3=x$   (B)$x=y^{-1}$   (C)$z^{-3}=y$   (D)$x=y^{-1}=z^3$   (Multiple answers may be correct)   I tried many approaches, one of them being: $1+log_zy=2log_yx$ $log_zz+log_zy=log_yx^2$ $log_z(yz)=log_yx^2$ But the fact that the bases are different is causing the main problem as I don't know how to proceed further. It would be great if anybody could give me a hint for solving such questions. NewForm.aspx disappeared How should spare change be exchanged? So I have about $50 in pennies, dimes and nickels.  What would you do with it?  I'm asking because I don't think spending hours rolling up the change and taking it to the bank is the best/most creative thing.  More info:  I took the change to the bank (not rolled up).  The banker asked me if I knew the exact amount... when all I had was a huge bag of change weighing like 30-40 pounds :-p  I said I didn't know the exact amount.  So the banker put all the change into a different bag, gave me a little receipt and said look for a deposit to your account in about a week.  Next time I'll just find a coinstar machine. I don't like waiting a week to have my change counted.  Also I'm sure the banker could fish out the quarters and no one would be the wiser :-) Word or phrase for mere coincidence that brings happiness How does TeX actually work? How long does it take to unlock another frame by playing one of the base frames? I'd like to get an advanced frame in Firefall. I've been told that I can use "Pilot Tokens" to unlock other frames without having to pay money.  How soon would I be able to unlock an advanced frame? Do I have to level a base frame all the way to level 40? More than once? As per the title, what hardware do I need to be able to run various versions of Android? Dependency problem with mysql-server-core-5.5 When I start the Ubuntu software centre, it says I cannot do anything until the package catalog is repaired. However, repairing fails.  I ran sudo apt-get -f install and found the problem to be:  mysql-server-5.5 depends on mysql-server-core-5.5 (= 5.5.24-0ubuntu0.12.04.1); however:   Version of mysql-server-core-5.5 on system is 5.5.28-0ubuntu0.12.04.2.   So, the question is, how do I install that version and resolve the dependency problem? Given a random square matrix of size $n\times n$ in the field $\mathbb F_2$, what is the probability that its determinant is $1$? (This is also the probability that the matrix is non-singular, since $\mathbb F_2$ only has the elements $0$ and $1$.) Can Dementors die? Based upon , J.K. Rowlings has apparently stated "You cannot destroy Dementors, though you can limit their numbers if you eradicate the conditions in which they multiply, ie, despair and degradation."  Does this mean that the number of Dementors is always either increasing or remaining the same?  If they cannot be destroyed, does that mean they are immortal?  Or do they die of "natural causes"? Evaluate the integral $$\int^{\frac{\pi}{2}}_0 \frac{\sin^3x}{\sin^3x+\cos^3x}\, \mathrm dx.$$  How can i evaluate this one? Didn't find any clever substitute and integration by parts doesn't lead anywhere (I think).
