This one is structured so ground truth genuinely didn&#8217;t exist at generation time \u2014 useful for studying calibration (ECE), hallucination patterns, and confidence-vs-accuracy relationships under real uncertainty instead of retrospective fitting.<\/p>\n<p>Note on compliance: realized prices and news text aren&#8217;t redistributed (licensing reasons) \u2014 there&#8217;s a hydration script to populate those fields yourself with your own data source, or you can just inspect pre-computed outcome comparisons and results on the companion site (glassballai.com\/results).<\/p>\n<p>Note Evaluation: Some tickers have very low run counts due to interrupted tracking or individual tracking runs that are not part of the fixed set of tracked stocks. They are included for full transparency and factor into the global metrics, but their individual ticker-level stats should be ignored due to high variance.<\/p>\n<p>Published on Hugging Face under CC-BY-NC-4.0: huggingface.co\/datasets\/louidev\/glassballai<\/p>\n<p>Happy to answer questions about the collection methodology or the metrics computed on top of it.<\/p>\n<\/div>\n<p><!-- SC_ON -->   submitted by   <a href=\"https:\/\/www.reddit.com\/user\/aufgeblobt\"> \/u\/aufgeblobt <\/a> <br \/> <span><a href=\"https:\/\/www.reddit.com\/r\/datasets\/comments\/1ux5vqo\/oc_live_timelocked_gemini_market_forecasts_for\/\">[link]<\/a><\/span>   <span><a href=\"https:\/\/www.reddit.com\/r\/datasets\/comments\/1ux5vqo\/oc_live_timelocked_gemini_market_forecasts_for\/\">[comments]<\/a><\/span><\/p><div class='watch-action'><div class='watch-position align-right'><div class='action-like'><a class='lbg-style1 like-41747 jlk' href='javascript:void(0)' data-task='like' data-post_id='41747' data-nonce='9de69db8d5' rel='nofollow'><img class='wti-pixel' src='https:\/\/www.graviton.at\/letterswaplibrary\/wp-content\/plugins\/wti-like-post\/images\/pixel.gif' title='Like' \/><span class='lc-41747 lc'>0<\/span><\/a><\/div><\/div> <div class='status-41747 status align-right'><\/div><\/div><div class='wti-clear'><\/div>","protected":false},"excerpt":{"rendered":"<p>Sharing a dataset I&#8217;ve been building: daily LLM inference outputs on stock market forecasting, captured before outcomes&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[85],"tags":[],"class_list":["post-41747","post","type-post","status-publish","format-standard","hentry","category-datatards","wpcat-85-id"],"_links":{"self":[{"href":"https:\/\/www.graviton.at\/letterswaplibrary\/wp-json\/wp\/v2\/posts\/41747","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.graviton.at\/letterswaplibrary\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.graviton.at\/letterswaplibrary\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.graviton.at\/letterswaplibrary\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.graviton.at\/letterswaplibrary\/wp-json\/wp\/v2\/comments?post=41747"}],"version-history":[{"count":0,"href":"https:\/\/www.graviton.at\/letterswaplibrary\/wp-json\/wp\/v2\/posts\/41747\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.graviton.at\/letterswaplibrary\/wp-json\/wp\/v2\/media?parent=41747"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.graviton.at\/letterswaplibrary\/wp-json\/wp\/v2\/categories?post=41747"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.graviton.at\/letterswaplibrary\/wp-json\/wp\/v2\/tags?post=41747"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
