Moco

moco, सेल्फ-सुपरवाइज्ड विज़ुअल रिप्रेजेंटेशन लर्निंग के लिए डिज़ाइन किए गए मोमेंटम कंट्रास्ट का एक PyTorch कार्यान्वयन है। यह एक ही इमेज के विभिन्न दृश्यों के बीच समानता को अधिकतम करके अनलेबल डेटासेट से उच्च-स्तरीय इमेज फीचर्स निकालने के लिए एक शोध-आधारित फ्रेमवर्क के रूप में कार्य करता है।

यह सिस्टम ट्रेनिंग को स्थिर करने के लिए एक तेज़-सीखने वाले ऑनलाइन एनकोडर और धीरे-धीरे विकसित होने वाले मोमेंटम एनकोडर से युक्त एक असममित एनकोडर आर्किटेक्चर का उपयोग करता है। यह एक डिक्शनरी-आधारित दृष्टिकोण का उपयोग करता है जो मैन्युअल मानव लेबलिंग के बिना विशिष्ट विज़ुअल फीचर्स सीखने के लिए नकारात्मक नमूनों की एक डायनामिक कतार के खिलाफ क्वेरी इमेज की तुलना करता है।

यह फ्रेमवर्क एंड-टू-एंड कंट्रास्टिव लर्निंग वर्कफ़्लो को कवर करता है, जिसमें अनसुपरवाइज्ड विज़ुअल रिप्रेजेंटेशन लर्निंग और अनलेबल इमेज विश्लेषण शामिल है। यह उच्च-आयामी वेक्टर समानता गणना और मॉडल ट्रेनिंग के लिए GPU-त्वरित टेंसर ऑपरेशन्स का लाभ उठाता है।
