ML | ResNet 殘差網路概述 殘差神經網路(Residual Neural Network,簡稱 ResNet ) 是一種深度學習模型,旨在解決傳統深度神經網路中常見的梯度消失和梯度爆炸問題。這種網路的核心理念是讓每一層學習與輸入之間的殘差,而非直接學習預期的輸出。這樣的設計使得訓練更深層的模型變得更為有效,並且在增加層數時能保持甚至提高準確率。 ResNet 透過 殘差學習解決了深度網路的退化問題,讓我們可以訓 2025-01-26 ML #NWP #AI #ML #ResNet
ML | VAE Variational Auto-Encoder 基礎知識回顧 Latent Variable Variations Gaussian Mixture Model Gaussian Mixture Model,即高斯混合模型。生成模型比較主流的三個模型為:隱馬可夫模型HMM、樸素貝葉斯模型NB、高斯混合模型GMM。這裡我們主要為大家介紹GMM。 混合模型是一個可以用來表示在總體分佈中含有N個子分佈的機率模型,它表示了觀測資料在總體中的機率分 2025-01-26 ML #NWP #AI #ML #VAE #Auto-Encoder #Generative AI
