The math says that you need a certain number of samples, per class, per # of features used to do classification. So it's hard to get around the "more classes => more samples" requirement.Karen Burnhamhttps://www.blogger.com/profile/16803309172414793939noreply@blogger.comtag:blogger.com,1999:blog-8573136768377847579.post-37305710882474185822009-07-08T12:13:21.485-05:002009-07-08T12:13:21.485-05:00It may be that you can engage in a little recursiv...It may be that you can engage in a little recursive hair-splitting.<br />My gut instinct tells me that any system capable of sorting golden age and earlier from later works could then do a second pass on the later works grouping and fairly easily determine whether something is new wave or not by measuring 'closeness' to the older group: those works that fall out as 50% or closer are not new wave - anything that is left is.<br />If 'gut instinct' bears out in a manual sort, you'll save time on the algorithm AND the number of works needed for your sample.Crotchety Old Fanhttps://www.blogger.com/profile/02092745636011711266noreply@blogger.comtag:blogger.com,1999:blog-8573136768377847579.post-58996862409813289602009-07-08T10:46:05.239-05:002009-07-08T10:46:05.239-05:00Yay Cordwainer Smith!

I'll have to think about some of the parallel-in-time categories. I can see where it would be much more complete, but would also make it harder to do initial sorting. Also, every extra category is a multiplier of data needed--I'd need ~90 Doc Smith and Ed Hamilton stories, ~90 post-singularity stories, etc. I'll definitely give it some thought, though.Karen Burnhamhttps://www.blogger.com/profile/16803309172414793939noreply@blogger.comtag:blogger.com,1999:blog-8573136768377847579.post-50522508624489353682009-07-08T04:40:10.336-05:002009-07-08T04:40:10.336-05:00If you really want to test boundaries, you've ...If you really want to test boundaries, you've got to include stories by Cordwainer Smith.<br /><br />In fact, a very good source for a wide diversity of material (styles, authors) would be the Del Rey series of books - The Best Ofs:<br />Fredric Brown, Henry Kuttner, Cordwainer Smith,C. L. Moore, Jack Williamson, Fritz Leiber, Robert Bloch, Philip K. Dick, Murray Leinster and multiple others in the series.<br /><br />I'd also suggest that: you periods need a little adjusting: for completeness sake - a Before the Golden Age period (say 1900 - 1934),<br />Golden Age - '34 to '58<br />post golden age '59 through '84 or so (traditional works not participating in the 'new wave')<br />new wave running parallel from '60 or so through mid 70's<br />and then after that you really have to represent multiple branches (I think.)<br />Hope that helps.Crotchety Old Fanhttps://www.blogger.com/profile/02092745636011711266noreply@blogger.comtag:blogger.com,1999:blog-8573136768377847579.post-57536449125910635802009-07-04T14:35:43.560-05:002009-07-04T14:35:43.560-05:00Duncan- That's a good point about the fact tha...Duncan- That's a good point about the fact that time hasn't filtered the latest stuff yet--see my inability to even come up with a good name for the period! That's one reason that I'm fishing for more obscure Golden Age & New Wave stories: I want to make sure that I'm not just comparing Asimov/Clarke/Heinlein to the wider diversity of voices writing today. <br /><br />When it comes to the Pattern Recognition, I'll be doing the initial classification (based on the dates), against which the program's classification will be measured.Karen Burnhamhttps://www.blogger.com/profile/16803309172414793939noreply@blogger.comtag:blogger.com,1999:blog-8573136768377847579.post-54965714104728311952009-07-04T11:04:22.491-05:002009-07-04T11:04:22.491-05:00I'll be fascinated to see if the error rate in...I'll be fascinated to see if the error rate increases across the three periods - for two reasons. Firstly, I suspect we have a pretty consistent idea of what Golden Age SF looked like, and the material which has survived to be transferred onto the internet may well be pretty consistent. Secondly, the modern era has not yet been through any comprehensive "canonisation" yet whilst the material, building on the longer history of SF, is less likely to be self-similar.<br /><br />I've got no idea of where the field of pattern recognition is. Does it make sense to get some human beans to do the same type of sorting of the works as a baseline?Duncan Lawiehttp://www.hoopoes.com/sf/noreply@blogger.com
