【東大オープンキャンパス2020】高校数学で理解する画像検索
Google画像検索のようなサービスでは、画像をアップロードすると、それに似ている画像をインターネット上から探すことが出来ます。このように、似ている画像を探す技術を「画像検索」と言います。本講義では、画像検索において速度・精度・メモリ消費量がどのように関連しあっているかを高校で扱う範囲の数学のみを用いて解説します。これにより、実世界のシステムを記述するためには高校数学の知識が重要な役割を果たすことを体験してもらいます。本発表は「高校生のための東京大学オープンキャンパス2020」において、「工学部 電気電子工学科・電子情報工学科」が分担した、公開講義です。

      then i think you should specify the criteria of output probability. if it is less than 30% then eliminate that O/p

    At 11:44, dist = q_norms[m] + x_norms[n] - **2** x ip[m][n]? Shouldn't ip[m][n] be multiplied by 2 (to match the formula on the top of the slide)?

    I expect that we can do better than kmeans clustering for dimension reduction and coarse quantization, for image data at least, by smart feature detection using transfer learning like ResNet50 as main body, plus VAE as head of network for smart dimension reduction. Also use built-in tensor quantization on the short vector, or build your own quantizer that is differentiable for purpose of backprop by custom sequential Relu activations that start at zero, which is stabdard relu, then 1,2,3,... Until it swept entire 8 bit range ie 256, or 16 bit range ie 16k. No more fine search is needed consequently, just direct addressing to correct hash bucket, and pull out an item from its list. Or you can search fine list other ways like pq or lsh .

    Heyyy, please help me. How can I make this without having to own 100 images. can't I use Imagenet's API or something to show results online ? I want to deploy this on heroku but don't want to put all the millions of images in my img folder
