【官方解讀】勁風(fēng)算法官方解讀

勁風(fēng)算法是一種使用多個(gè)模型進(jìn)行組合預(yù)測(cè)的算法。它不僅可以捕捉不同模型之間的多樣性，還可以有效地避免模型選擇的偏差。在算法中，通過(guò)將多個(gè)模型的預(yù)測(cè)結(jié)果進(jìn)行加權(quán)或組合來(lái)得到最終的預(yù)測(cè)結(jié)果。這樣做的好處在于可以進(jìn)一步提高預(yù)測(cè)準(zhǔn)確性，并避免了單個(gè)模型預(yù)測(cè)精度不足的問(wèn)題。同時(shí)，勁風(fēng)算法可應(yīng)用于各種領(lǐng)域的數(shù)據(jù)分析與預(yù)測(cè)中。

關(guān)于百度上線 “閃電算法”的公告

2017年10月初，“閃電算法”上線，移動(dòng)搜索頁(yè)面首屏加載時(shí)間將影響搜索排名。移動(dòng)網(wǎng)頁(yè)首屏在2秒之內(nèi)完成打開的，在移動(dòng)搜索下將獲得提升頁(yè)面評(píng)價(jià)優(yōu)待，獲得流量?jī)A斜；同時(shí)，在移動(dòng)搜索頁(yè)面首屏加載非常慢（3秒及以上）的網(wǎng)頁(yè)將會(huì)被打壓。廣大站長(zhǎng)優(yōu)化頁(yè)面首屏加載時(shí)間，優(yōu)化的技術(shù)建議包括但不限于:資源加載：1、將同類型資源在服務(wù)器端壓縮合并，減少網(wǎng)絡(luò)請(qǐng)求次數(shù)和資源體積。2、引用通用資源，充分利用瀏覽器緩存。3

百度搜索持續(xù)與有損用戶體驗(yàn)的落地頁(yè)廣告作戰(zhàn)

百度搜索持續(xù)與有損用戶體驗(yàn)的落地頁(yè)廣告作戰(zhàn)指的是百度搜索廣告系統(tǒng)中，存在一些廣告落地頁(yè)的問(wèn)題，這些問(wèn)題可能導(dǎo)致用戶體驗(yàn)不佳或者受到欺詐等不良影響。以下是對(duì)這一問(wèn)題進(jìn)行的一些解決措施的可能作戰(zhàn)方案： 1. 加強(qiáng)廣告審核: 百度可以增加廣告審核的力度，確保廣告內(nèi)容真實(shí)可靠，并要求廣告主提交可信的落地頁(yè)鏈接，防止用戶被重定向到不良網(wǎng)站或存在欺詐行為的頁(yè)面。 2. 提高廣告位質(zhì)量得分: 百度可以建立一

【官方解讀】勁風(fēng)算法官方解讀

2月27日，百度搜索資源平臺(tái)發(fā)布了《勁風(fēng)算法即將上線》的官方公告，針對(duì)惡劣聚合頁(yè)問(wèn)題進(jìn)行規(guī)范和控制。為了更好的幫助廣大開發(fā)者了解勁風(fēng)算法，避免出現(xiàn)類似問(wèn)題影響站點(diǎn)、智能小程序在搜索中的表現(xiàn)，我們結(jié)合算法發(fā)布后大家關(guān)注度較高的問(wèn)題逐一拆解說(shuō)明，請(qǐng)廣大開發(fā)者參考。本次勁風(fēng)算法主要針對(duì)以下四類惡劣聚合頁(yè)問(wèn)題：一、內(nèi)容跨領(lǐng)域頁(yè)面內(nèi)容與站點(diǎn)本身所屬領(lǐng)域不符，或站點(diǎn)無(wú)專注領(lǐng)域，多為采集拼湊內(nèi)容。整改建議：1、

勁風(fēng)算法即將上線

近期，百度搜索技術(shù)團(tuán)隊(duì)發(fā)現(xiàn)，部分網(wǎng)站及智能小程序通過(guò)惡意構(gòu)造聚合頁(yè)面內(nèi)容來(lái)獲取搜索排名，獲得搜索用戶關(guān)注。為了保障搜索用戶的體驗(yàn)、保證搜索結(jié)果公平，百度搜索將于近期上線勁風(fēng)算法，控制惡意構(gòu)造聚合頁(yè)的問(wèn)題對(duì)搜索用戶的影響。聚合頁(yè)，是指頁(yè)面并無(wú)文章主體內(nèi)容，而是多個(gè)頁(yè)面的索引鏈接圍繞在特定主題下的信息整合頁(yè)。針對(duì)惡劣聚合頁(yè)問(wèn)題，搜索一經(jīng)識(shí)別，將會(huì)結(jié)合站點(diǎn)及智能小程序的用戶評(píng)價(jià)，限制其在搜索結(jié)果中的展現(xiàn)
