I need help with a chemistry question?
E=m x c x change in temp. (C represents specific heat capacity of water) Substitute the values from the question and find m m= E/c x change in temp. m= (1.69 x 10^4)/4.2 x (100-23) =52.3g
Fixed and Variable Inputs?
Fixed inputs are things you can't easily change (that is, things that only change in the long-run). Variable inputs are things you can easily change (things that change in the short run). So... Fixed inputs: - Your building (because you own or lease it (binding contract)) - Your video library (it would be hard to sell all this off easily and not lose a ton of money) - Your shelves and any other interior decoration you might have paid for when you opened the store (the more permanent stuff like carpet and counters, etc) Variable inputs: - Your employees (you can fire/hire people easily) - Your bills (if you shut down, you can stop paying heat/electricity, even though you can't get rid of the building as easily) - Your cleaning service or other such things (some video stores have food and drinks for sale, stuff like that you can stop ordering) Customers are NOT an input (as in other answer!). Inputs are another word for costs. Your customers don't cost you anything!

What are some possible knowledge questions for the title "robust knowledge requires both consensus and disagreement"?
OK a few questions and some statements about your topic(I disagree about robust knowledge ever requiring disagreement - if the rule of testing is always enforced then test-failure immediately refutes it is as knowledge)consensus also applies to belief eg we all believe that money confers value. If we drop that consensus then the economic system collapses. (Quantative easing is a complete con which is being used to prop up that belief for example.) ( And the bitcoin is an attempt to capitalise on the nature of belief and make short term “money” for the fiancial gambling fraternity. - best avoided)What is the difference between knowledge , belief and faith?The scientific method requires testing theories against real world input - this make it robust but not true.The value of knowledge is that its has been tested and accepted, whereas belief is always negotiable.In the limit scientific knowledge tends to being true. (asymptotically aproaches truth)You can question belief but knowledge tends to be accepted, faith is not testable and it is bad form to negotiate it.To present faith as truth is also bad form.The most basic knowledge is the appropriate and persistent response to input (ie stimulus-response)To disagree with beliefs is reasonable , to disagree with faith is reasonable, but to disagree with (accepted) knowledge requires a deep level of understanding and is always suspect.In forming a basis for all future decisions prefer knowledge over belief .Knowledge is a refined form of information (ie it is been tested (prediction and test) against reality)The internet is a source of predominantly raw information. Assume that it has not been tested. (Knowledge has much greater value than just sources of information)
Help to write a program in C/C++ to grade a multiple choice exam?
Check out the revised code at this location http://pastebin.com/f53829935 This was actually the only problem I really had: fprintf(output,"%3d\t%3.0f\n",id,tot/(... From point of view of the "reader side" this code was truncated. This happens, if word wrapping in the code windows cannot take place, because the word is too big. The line above I preceded with the following code fragment: float fPercentage = tot * 1.0; fPercentage /= ((tot + iMissed) * 1.0); fPercentage *= 100; fprintf(output, "%3d\t%5.0f%%\n", id,fPercentage); This took care of the integer division, which otherwise would result in 1 or 0 depending on the rounding. I thought your work was actually pretty complete. I did not have problems with the file. I actually made a full path to the file and that could be part of the problem you reported. All the best.
Why are the updated weights moving at the just one direction at the backpropagation algorithm?
I didn’t understand what you meant by “just one direction” in the question title, but after reading the comment I think you are worried that one sample is causing such a big change in the weights that the other samples don’t seem like they matter.If this is the case, perhaps the network is doing the right thing — it is doing such a bad job on that one example that it really needs to change the weights a lot to try to account for it.However, the other 10 examples aren’t completely ignored; they are factoring into that average weight as well. So the network should, in parallel, be learning how to correctly classify the other 9 examples. It will keep making adjustments to try to classify the other example too, but if things are working right it will be aiming for a local minimum where the error is as low as possible.Perhaps you just need a larger training set; then the effect of one outlier won’t be as significant. Also, maybe you need to decrease the batch size. If the SGD algorithm you can apply the delta for just one example at a time if you want to; you don’t have to sum them all first. Roughly speaking, because the loss function is linear with respect to the different examples in the batch, it’s not a big problem usually to look at smaller batches instead of all examples at once.Finally, you may want to look at the weight initialization of your network, input ranges and activation functions, etc., and make sure everything is behaving nicely as it trains. Make sure the weights aren’t blowing up to infinity or dropping down to 0, etc. These sorts of problems could also make training behave differently than you expect.
Where can I find HTML code for a "blue colored letter A" button?
Seriously? This is a pretty lazy question. Not even sure why I answered it, there’s millions of answers to this kind of basic css question already on google. Here’s a few samples I just threw together it covers both input type = button and the button tag which can be more problematic. Copy this to a new page and open it in a browser and you can see what each example does.
How can I create a link in Quora using my own text as the link description?
Anyone can do this by:Using the @ button to create a link to an object on Quora.Editing the text of the link -- easiest way is to put your cursor in the middle of the question text and start writing what you want it to be and delete everything else around it.

How do you format the title of a poem in an essay?
Put quotation marks around the poem's title unless it is a novel-length epic poem, such as "Paradise Lost" or "The Divine Comedy." In that case, italicize or underline the title. Cite the poem with a parenthetical citation if you are using MLA or APA format.
