Ma'auni na Kimantawa:

1. Maido da Guntun Bidiyo: Bayan an ba da furucin da aka faɗa (labari), dawo da ɓangaren bidiyo daidai daga cikin zaɓaɓɓun 'yan takara. Yana auna daidaitaccen ma'ana mai ƙarfi.
2. Kimantawa Mai Sarrafawa (Tsarin Kallon Zaɓi): An yi wahayi daga ilimin halayyar ci gaba (Hirsh-Pasek & Golinkoff, 1996).

Asarar Bambanci (Ra'ayi): Tsarin yana koyo ta hanyar kwatanta nau'ikan biyu masu kyau (sauti $a_i$ da bidiyo $v_i$ masu dacewa) da nau'ikan biyu marasa kyau (sauti $a_i$ da bidiyo $v_j$ marasa dacewa).

Tsarin asarar triplet mai sauƙi yana nufin gamsar da: $$\text{nisa}(f(a_i), g(v_i)) + \alpha < \text{nisa}(f(a_i), g(v_j))$$ domin duk marasa kyau $j$, inda $f$ da $g$ su ne ayyukan haɗakar sauti da bidiyo, kuma $\alpha$ shine gefe. Asarar ainihin da aka rage yayin horarwa ita ce: $$L = \sum_i \sum_j \max(0, \, \text{nisa}(f(a_i), g(v_i)) - \text{nisa}(f(a_i), g(v_j)) + \alpha)$$

Wannan yana tura haɗakar nau'ikan biyu na sauti-bidiyo masu dacewa kusa da juna a cikin sararin samaniya gama gari yayin da ake tura nau'ikan biyu marasa dacewa.

5. Tsarin Nazari: Fahimta ta Asali & Zargi

Fahimta ta Asali: Wannan takarda magani ce mai mahimmanci kuma mai ƙarfin gwiwa ga sha'awar fagen da ke da tsaftataccen bayanai. Ta nuna cewa ƙalubalen ainihi—kuma gwajin gaskiya na yuwuwar fahimtar tsarin—ba shine cimma SOTA akan bayanan da aka tsara ba, amma koyo mai ƙarfi daga sigina mai rikitarwa, mai rikitarwa na gogewar ainihi. Amfani da Peppa Pig ba wasa ba ne; yana da kyakkyawan kwaikwayon muhallin harshe na yaro, inda tattaunawa ba ta zama cikakkiyar bayanin sauti ba.

Kwararar Ma'ana: Hujja tana da sauƙi mai kyau: 1) Gano gurbi mai mahimmanci (rashin ingancin muhalli). 2) Ba da shawarar magani mai ka'ida (bayani masu ruɗani, na halitta). 3) Aiwatar da tsarin madaidaici don gwada tushen. 4) Kimantawa tare da ma'auni na aikace-aikace (maido) da na fahimta (kallon zaɓi). Kwararar daga ma'anar matsala zuwa ƙarshe mai tushe ta shaida ba ta da lahani.

Ƙarfi & Kurakurai:

• Ƙarfi: Ƙirƙirar hanyoyi tana da zurfi. Ta hanyar raba bayanan horarwa (tattaunawa) da bayanan kimantawa (labari), sun ƙirƙiri wurin gwaji mai sarrafawa amma na ainihi. Wannan ƙira ya kamata ta zama ma'auni.
• Ƙarfi: Haɗa ƙirar lissafi tare da ilimin halayyar ci gaba (tsarin kallon zaɓi) shine mafi kyawun aiki wanda ya kamata ƙarin binciken AI ya karɓa.
• Kuskure: "Tsarin bi-modal mai sauƙi" ya kasance takobi mai kaifi biyu. Yayin da yake tabbatar da cewa bayanan sun fi mahimmanci, ya bar buɗe ko ƙarin tsarin ci gaba (misali, masu canzawa, hankalin nau'ikan biyu) zai haifar da fahimta daban-daban na inganci ko aiki mafi girma. Fagen, kamar yadda aka gani a cikin ayyuka kamar na Radford et al.'s CLIP, ya matsa zuwa haɓaka duka girman bayanai da girman tsarin.
• Kuskure Mai Muhimmanci: Takardar ta nuna amma ba ta cika magance matsalar rashin daidaiton lokaci ba. A cikin tattaunawa, wani hali na iya cewa "Na ji tsoro jiya" yayin da yake murmushi a kan allo. Ta yaya tsarin ke ɗaukar wannan cikas na lokaci mai tsanani? Kimantawa akan labarai masu bayyanawa ya kawar da wannan matsala mai wahala.

Fahimta Mai Aiki:

1. Ga Masu Bincike: Bar gatanci na bayanai masu daidaito cikakke. Bayanan gaba don koyo mai tushe dole ne su ba da fifiko ga hayaniyar muhalli. Al'umma ya kamata su daidaita akan rabon kimantawa kamar wanda aka ba da shawarar a nan (horar da ruɗani / gwaji mai tsafta).
2. Ga Ƙirar Tsarin: Saka hannun jari a cikin hanyoyin warware masu rikitarwa.

3. Ga Fagen: Wannan aikin mataki ne zuwa ga wakilai waɗanda ke koyo a cikin daji. Mataki na gaba shine haɗa ɓangaren aiki—ba da damar tsarin yin tasiri ga shigar sa (misali, yin tambayoyi, mai da hankali) don warware shubuha, motsawa daga kallo mara aiki zuwa koyo mai hulɗa.

6. Aikace-aikace na Gaba & Hanyoyin Bincike

1. Fasahar Ilimi Mai Ƙarfi: Tsarin da aka horar akan wannan ƙa'ida zai iya ƙarfafa ƙarin kayan aikin koyon harshe masu daidaitawa ga yara, masu iya fahimtar maganar ɗalibi a cikin muhalli mai ruɗani, na yau da kullun da kuma ba da ra'ayi na mahallin.

2. Hulɗar Mutum-Robobi (HRI): Don robobi su yi aiki a cikin sararin samaniya na ɗan adam, dole ne su fahimci harshe da aka kafa a cikin duniyar fahimta gama gari, mai rikitarwa. Wannan binciken yana ba da tsari don horar da irin waɗannan robobin akan rikodin tattaunawar ɗan adam-robobi ko ɗan adam-ɗan adam na halitta.

3. Kimiyyar Fahimi & Daidaitawar AI: Wannan layin aikin yana aiki azaman wurin gwaji don ka'idodin samun harshe na ɗan adam. Ta hanyar haɓaka rikitarwa (misali, ta amfani da labarai masu tsayi), zamu iya bincika iyakokin koyon rarraba da buƙatar son zuciya.

4. Tsarin Tushe na Nau'ikan Biyu na Ci Gaba: Tsarin na gaba kamar GPT-4V ko Gemini suna buƙatar bayanan horarwa waɗanda ke nuna rashin ƙarfin haɗin kai na ainihi. Tsara manyan bayanai, "masu ruɗani-tushe" bisa ga tsarin Peppa Pig hanya ce mai mahimmanci.

5. Haɗawa tare da Manyan Tsarin Harshe (LLMs): Hanya mai ban sha'awa ita ce amfani da haɗakar da aka kafa daga tsarin kamar wannan a matsayin hanyar sadarwa tsakanin fahimta da LLM. LLM na iya yin tunani akan haɗakar ma'ana da aka warware, haɗa tushen fahimta tare da ƙwararrun ilimin harshe na baya.
