computer vision - What is the number of Hash functions needed in Bundle Min Hashing for Logo Recognition? -

लोगो के संदर्भ में लोगो मान्यता के लिए बंडल न्यूनतम हैशिंग:

मान लीजिए कि हमारे पास बंडल {2,5,18,444,678} और {2,5,79,368,841} हैं और शब्दावली का आकार 1M है यदि हमारे पास केवल 1 स्केच प्रति बंडल है तो हमें 1 हां फंक्शन की आवश्यकता है जो 1 एम पूर्णांक को [0,1] में समान वितरण से मूल्यों के निर्धारण के लिए निर्धारित करता है। प्रत्येक कॉल के लिए हैश फ़ंक्शन को निश्चित बीज होना चाहिए। 4-स्केच के लिए हमें 4 बीजों के साथ ही हैश फ़ंक्शन की आवश्यकता होती है। क्या विचार सही है?

या हम बेतरतीब ढंग से सेट (बंडल) से न्यूनतम हश शब्द के रूप में एक संख्या चुन सकते हैं, क्योंकि वे सेट के यादृच्छिक क्रमबद्धता का प्रतिनिधित्व करते हैं?

कागज में आवश्यक हैश फ़ंक्शंस?

क्या मुरमुरहेश 3 काम कर सकता है?

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
