previouslly I was extracting the grad on the weights. now it's the grad on the outputs/activations which seems better although perhaps harder to classify!

I can\\'t say whether the post-WWII British comedies produced at the Ealing Studios are an acquired taste or not, but I am completely addicted, and The Man in the White Suit is one of the best. No need to go into the well-known plot about the threat posed to both the textile industry and the textile unions by an indestructible, dirt-resistant fiber. Suffice it to say that the slings and arrows suffered by the naively idealistic Sidney Stratton in pursuing his polymer vision make for a comedic delight. Many of the well-known faces from the world of British character actors - the nervous Cecil Parker, the suavely devious Michael Gough, and the bluntly ruthless Ernest Thesinger - put in wonderful performances. Guinness - as always and forever - is superb, and Joan Greenwood is delectable as Daphne (just the way she enunciates the word \"Daddy\", makes the entire movie worth seeing).<br /><br />\"Knudsen!!!!!!!\"\\n\\n\\n\\n### Response:\\nnegative\\n\\n### Instruction\\nThe following movie review expresses what sentiment?

At the end of a long busy day it\\'s nice to kick back and have a great laugh before you go to sleep. I was so sad they took the show off air... at least we still have the re-runs!!

The plot involves the group of friends as it comes to light that Eddy left as a means to deal with death of a friend in which he feels in some way responsible. But this is inconsequential, as the choices made in the production are extremely poor and not fully realized. Screenplays not always need be \\'chatty\\', but they should at least assist the development of the story. Here one line attempts such as \"he just took off\" or \"I know you don\\'t have love in heart\" just do fully evoke something worth the audience\\'s time. Also whenever the writer feels at a loss to where to go to next he cuts to a music montage of the protagonist walking through fields to some indie mood music. Talk about trying to hard. If you are interested in a good film, the type that gives quality and substance over just style then this is not the film for you. \\'\\'\\'\\n\\nBetween 0 and 1, which is the sentiment of this example?\\n\\n\\n### Response:\\n0\\n\\n### Instruction\\nConsider the following example: \\'\\'\\' Well the reason for seeing it in the cinema was that it was a sneak preview, else I would never have seen this terrible teenage slasher movie.
