Not sure why they made such a stupid design choice in mathematica, and why it continues in alpha. Nevertheless, one can't blame NKS for this design choice that goes back to mathematica :)Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-57409705843234669262009-12-26T21:41:04.800-05:002009-12-26T21:41:04.800-05:00> I look forward to your examples of the unreli...> I look forward to your examples of the unreliability of Alpha, which you would no doubt put on slashdot soon.<br /><br />I'm not the same anon, but<br />http://www.wolframalpha.com/input/?i={{0%2C1}%2C{1%2C-7}}+*+{{7%2C1}%2C{1%2C0}}<br /><br />shows that W|A thinks that [0,1;1,-7] times its inverse [7,1;1,0] is *not* the identity matrix.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-55163727059710048742009-12-26T21:27:09.524-05:002009-12-26T21:27:09.524-05:00I think the story referenced is

Even some near future version of Wolfram Alpha may be smart enough to know that "some of NKS is broken" and "alpha may have some connection to NKS" does not imply much about the reliability of alpha.<br /><br />In fact, I am not sure Wolfram Alpha has anything to do with NKS. It contains an online version of Mathematica, and has reasonably good NLP skills. It has access to several databases that it can look up in a sensible way. It can be useful for certain things (e.g. type in "1,1,2,3,5,..." or "1+1/4+1/9+..." or "integrate .1 to .2 sin x/ x "). At least these parts have exactly zero connection to NKS, as far as I can tell.<br /><br />I look forward to your examples of the unreliability of Alpha, which you would no doubt put on slashdot soon.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-90633797647608054222009-12-24T02:04:03.642-05:002009-12-24T02:04:03.642-05:00WolframAlpha isn't worth even mentioning.

A mathematician disproved like 1000 claims. Now, assume that your output result you obtain via wolfram alpha are as reliable as claims made by nks. <br /><br />no wonder how uncreative Microsoft's BING is, it relies on something as unreliable as Wolfram.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-8937084169993702012009-12-23T18:37:16.654-05:002009-12-23T18:37:16.654-05:00Talking of wolframalpha, wouldn't the bing iph...Talking of wolframalpha, wouldn't the bing iphone app actually suffice?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-17555922553228562022009-12-23T12:19:21.284-05:002009-12-23T12:19:21.284-05:00Lance, I am disappointed by you making hype about ...Lance, I am disappointed by you making hype about wolframalpha.

I propose instead that you pick threads that run through all the episodes and evaluate them. e.g.,<br /><br />What is the probability that a randomly chosen character is compelling? You may want to assume you sample according to screen time or importance to the story.<br /><br />What is the probability that a randomly chosen actor will deliver a good performance? Again, you probably want to sample according to screen time.<br /><br />What is the probability that a randomly chosen writer will deliver a good script?<br /><br />What is the probability that story elements brought up in earlier episodes will pay off in later episodes?<br /><br />What is the probability that the story will have a satisfying conclusion?<br /><br />etc. Then you can define value preferences: how much do I value good acting versus a good ending; how much do I value good characters versus a good story; and so on.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-49420509381836106062009-12-22T13:11:12.585-05:002009-12-22T13:11:12.585-05:00I know we do it all the time in theory PCs, but is...I know we do it all the time in theory PCs, but is there any actual meaning to taking averages when given input in the form of human rankings on a scale of 1 to 10?
