提问 HN：推荐系统越来越差了吗？
1 分•作者: 0xPIT•7 个月前
我感觉所有推荐给我的内容，比如在 Instagram、YouTube 上，或者在商店里，都非常蠢，都是千篇一律的东西。<p>YouTube 就是一个很糟糕的例子，看一个关于某个艺术家的视频，推荐里就会全是关于那个艺术家的内容。而且你还无法摆脱这些“推荐”。<p>但其他大多数平台也一样。如果你有明确的需求，情况会更糟。如果你搜索某个高端品牌，它仍然会推荐低端产品。如果你是左撇子，它还是会推荐右撇子的东西。<p>这对这些平台来说，到底是如何实现良好转化的？是什么阻碍了它们向用户展示优质、有用且相关的推荐呢？

I feel that all my recommended contents, like on Instagram, YouTube, or in shops is really dumb more-of-the-same.<p>YouTube is a really bad example, watch one video about one artist, the feed will be full of just exactly that artist. And one can’t get rid of those “recommendations”.<p>But the same is true on most other platforms. It’s even worse if you are somehow specific. If you look for a specific premium brand, it will still recommend low-end stuff. If you are left handed, it will still recommend right handed stuff.<p>How does this really convert well for the platforms? What seems to prevent everyone to show users good, useful relevant recommendations?
