essential tool for large language models (LLM) and other modern generative AI models. We&#039;ll learn how text can be represented as numerical vectors using different methods. Understanding word embeddings, you gain valuable insights into natural language processing and how AI models interpret text. \ud83d\udd11 TIMESTAMPS \u2580\u2580\u2580\u2580\u2580\u2580\u2580\u2580\u2580\u2580\u2580\u2580\u2580\u2580\u2580\u2580\u2580\u2580\u2580\u2580\u2580\u2580\u2580\u2580\u2580\u2580 0:00 - What are word embeddings? 0:55 - Frequency-based methods 4:26 - Embeddings 8:56 - What is embedding space? 10:39 - How are embedding created? 16:28 - How to use pre-trained embedding models #deeplearning #ai #datascience #ThuVu\"><\/div><\/div><div class=\"lL\" style=\"max-width:100%;width:853px;margin:5px auto;\"><\/div><figcaption><\/figcaption><\/figure>","protected":false},"excerpt":{"rendered":"<p>\u4eba\u5de5\u667a\u6167\uff08AI\uff09\u8207\u6a5f\u5668\u5b78\u7fd2\u7684\u5e95\u5c64\u5b8c\u5168\u662f\u7531\u6578\u5b78\u69cb\u5efa\u800c\u6210\u7684\u3002\u5982\u679c\u8981\u7cfb\u7d71\u6027\u5730\u5217\u51fa\u6240\u6709 AI \u9700\u8981\u7684\u6578\u5b78\u57fa\u790e\uff0c\u53ef\u4ee5\u5c07\u5b83\u5011\u5206\u70ba\u300c\u56db\u5927\u6838\u5fc3\u652f\u67f1\u300d\u4ee5\u53ca\u300c\u4e09\u5927\u5ef6\u4f38\u8207\u9ad8\u968e\u9818\u57df\u300d\u3002 \u4ee5\u4e0b\u662f\u70ba\u4f60\u6574\u7406\u7684\u5b8c\u6574 AI \u6578\u5b78\u5730\u5716\uff1a \u6838\u5fc3\u652f\u67f1\u4e00\uff1a\u7dda\u6027\u4ee3\u6578 (Linear Algebra) \u2014\u2014 \u7a7a\u9593\u8207\u8cc7\u6599\u7684\u8f49\u63db \u7dda\u6027\u4ee3\u6578\u662f AI \u8655\u7406\u8cc7\u6599\u7684\u8a9e\u8a00\u3002\u5728 AI \u4e2d\uff0c\u6240\u6709\u7684\u8cc7\u6599\uff08\u6587\u5b57\u3001\u5716\u7247\u3001\u8072\u97f3\uff09\u90fd\u6703\u88ab\u8f49\u63db\u6210\u5411\u91cf\u548c\u77e9\u9663\u3002 \u6838\u5fc3\u652f\u67f1\u4e8c\uff1a\u5fae\u7a4d\u5206 (Calculus) \u2014\u2014 \u6a21\u578b\u7684\u5b78\u7fd2\u8207\u512a\u5316 \u5fae\u7a4d\u5206\u8ca0\u8cac\u89e3\u6c7a AI \u5982\u4f55\u300c\u5f9e\u932f\u8aa4\u4e2d\u5b78\u7fd2\u300d\u7684\u554f\u984c\u3002\u900f\u904e\u8a08\u7b97\u8b8a\u5316\u7387\uff0cAI \u624d\u80fd\u8abf\u6574\u81ea\u8eab\u53c3\u6578\u3002 \u6838\u5fc3\u652f\u67f1\u4e09\uff1a\u6a5f\u7387\u8207\u7d71\u8a08 (Probability &amp; Statistics) \u2014\u2014 \u8655\u7406\u4e0d\u78ba\u5b9a\u6027 AI \u7684\u672c\u8cea\u662f\u5728\u5145\u6eff\u96dc\u8a0a\u7684\u73fe\u5be6\u4e16\u754c\u4e2d\u505a\u51fa\u300c\u6700\u4f73\u731c\u6e2c\u300d\uff0c\u6a5f\u7387\u8ad6\u63d0\u4f9b\u4e86\u91cf\u5316\u4e0d\u78ba\u5b9a\u6027\u7684\u5de5\u5177\uff0c\u7d71\u8a08\u5b78\u5247\u63d0\u4f9b\u4e86\u5f9e\u8cc7\u6599\u4e2d\u62bd\u53d6\u51fa\u898f\u5f8b\u7684\u65b9\u6cd5\u3002 \u6838\u5fc3\u652f\u67f1\u56db\uff1a\u6700\u4f73\u5316\u7406\u8ad6 (Optimization Theory) \u2014\u2014 \u5c0b\u627e\u6700\u5b8c\u7f8e\u7684\u89e3\u7b54 \u5fae\u7a4d\u5206\u7d66\u4e86\u6211\u5011\u5de5\u5177\uff0c\u6700\u4f73\u5316\u7406\u8ad6\u5247\u7d66\u4e86\u6211\u5011\u300c\u5c0b\u627e\u6700\u4f73\u89e3\u7684\u7b56\u7565\u8207\u5730\u5716\u300d\u3002 \u5ef6\u4f38\u9818\u57df\u4e94\uff1a\u8cc7\u8a0a\u8ad6 (Information Theory) \u2014\u2014 \u8861\u91cf\u5b78\u7fd2\u6548\u7387 \u8cc7\u8a0a\u8ad6\u539f\u672c\u7528\u65bc\u901a\u8a0a\uff0c\u4f46\u5728 AI \u4e2d\uff0c\u5b83\u88ab\u7528\u4f86\u91cf\u5316\u8cc7\u8a0a\u91cf\u4ee5\u53ca\u6a21\u578b\u9810\u6e2c\u7684\u6e96\u78ba\u5ea6\u3002 \u5ef6\u4f38\u9818\u57df\u516d\uff1a\u96e2\u6563\u6578\u5b78\u8207\u5716\u8ad6 (Discrete Mathematics &amp; Graph Theory) \u2014\u2014 \u7d50\u69cb\u5316\u95dc\u806f \u7576\u8cc7\u6599\u4e0d\u662f\u6574\u9f4a\u7684\u8868\u683c\uff0c\u800c\u662f\u8907\u96dc\u7684\u7db2\u8def\u6216\u908f\u8f2f\u95dc\u4fc2\u6642\uff0c\u5c31\u9700\u8981\u96e2\u6563\u6578\u5b78\u3002 [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"ai_generated_summary":"","footnotes":""},"class_list":["post-3801","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/infernews.com\/blog\/wp-json\/wp\/v2\/pages\/3801","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/infernews.com\/blog\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/infernews.com\/blog\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/infernews.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/infernews.com\/blog\/wp-json\/wp\/v2\/comments?post=3801"}],"version-history":[{"count":4,"href":"https:\/\/infernews.com\/blog\/wp-json\/wp\/v2\/pages\/3801\/revisions"}],"predecessor-version":[{"id":9719,"href":"https:\/\/infernews.com\/blog\/wp-json\/wp\/v2\/pages\/3801\/revisions\/9719"}],"wp:attachment":[{"href":"https:\/\/infernews.com\/blog\/wp-json\/wp\/v2\/media?parent=3801"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
