全格局使用PyTorch - 深度學習和圖神經網路 - 基礎篇
為了解決Numpy softmax 的問題,作者李金洪 這樣論述:
深度學習擅長處理結構規則的多維資料(歐氏空間),但現實生活中,很多不規則的資料如:社群、電子商務、交通領域,多是之間的關聯資料。彼此間以龐大的節點基礎與複雜的互動關係形成了特有的圖結構(或稱拓撲結構資料),這些資料稱為「非歐氏空間資料」,並不適合用深度學習的模型去分析。 圖神經網路(Graph Neural Networks, GNN)是為了處理結構不規則資料而產生的,主要利用圖結構的資料,透過機器學習的方法進行擬合、預測等。 〇 在結構化場景中,GNN 被廣泛應用在社群網站、推薦系統、物理系統、化學分子預測、知識圖譜等領域。 〇 在非結構化領域,GNN 可以用在圖
型和文字等領域。 〇 在其他領域,還有圖生成模型和使用 GNN 來解決組合最佳化問題的場景。 市面上充滿 NN 的書,但卻沒有一本完整說明 GNN,倘若不快點學這個新一代的神經網路,你會用的普通神經網路馬上就會落伍了!非歐氏空間才是最貼近人類生活的世界,而要真正掌握非歐氏空間的問題解決,GNN 是你一定要學的技術,就由本書一步步帶領你完全攻略! 〇 使用 Graph 概念取代傳統的歐氏空間神經元 〇 最好用的 PyTorch + Anaconda + Jupyter 〇 從基礎的 CNN、RNN、GAN 開始上手神經網路 〇 了解基礎的啟動函數、損失函數、L1/
L2、交叉熵、Softmax 等概念 〇 NLP 使用神經網路處理 + 多頭注意力機制 〇 Few-shot/Zero-shot 的神經網路設計 〇 空間域的使用,使用 DGL、Networkx 〇 利用 GNN 進行論文分類 本書特色 ~GNN 最強入門參考書~ ● 以初學者角度從零開始講解,消除讀者學習過程跳躍感 ● 理論和程式結合,便於讀者學以致用 ● 知識系統,逐層遞進 ● 內容貼近技術趨勢 ● 圖文結合,化繁為簡 ● 在基礎原理之上,注重通用規律
針對類別增量學習的多錨點知識蒸餾和連續動態調整之特徵邊距
為了解決Numpy softmax 的問題,作者陳殿善 這樣論述:
在類別增量學習中,當已經擁有辨識舊類別能力的模型被要求進一步學習辨識新添加的類別時,通常會導致模型對於舊類別產生遺忘以致於在舊類別上的辨識能力下降,這個問題被稱作災難性遺忘 (catastrophic forgetting)。現存有許多方法是基於知識蒸餾 (knowledge distillation) 的技術,試圖在學習新添加的類別的同時保留模型對已學習類別的知識來緩解災難性遺忘的問題,本文進一步提出多錨點蒸餾目標 (multi-anchor distillation objective) 以更進一步減輕災難性遺忘,其藉由訓練模型時同時約束特徵空間中的輸入資料和每個舊類別的多個類別嵌入 (
class embeddings) 之間的空間關係來實現。此外,由於增量學習的知識蒸餾一般依賴於保留一個經驗重播緩衝區(knowledge replay buffer)來儲存已見類別的樣本,但由於緩衝區的大小有限,同時也會帶來了另一個類別不平衡的問題:每個已學習類別的樣本數量逐漸減少,導致與新類別的樣本數量相差愈多。因此,我們提出將連續動態調整之特徵邊距 (continually-adapted margin) 引入分類目標函數中,以解決由類別不平衡引起的對新類別的預測偏差。我們對各種數據集和設定進行了廣泛的實驗,證明我們提出的類別增量學習方法相比於幾個最先進的方法更有效以及得到更優越的性能。
機器學習演算法動手硬幹:用PyTorch+Jupyter最佳組合達成
為了解決Numpy softmax 的問題,作者孫玉林,余本國 這樣論述:
★★★【機器學習】+【演算法】★★★ ★★★★★【PyTorch】+【Jupyter】★★★★★ 一步一腳印、腳踏實地 機器學習經典演算法全面講解 我們平常視為理所當然的L1、L2、Softmax,Cross Entropy,都是基礎的機器學習所推導出來的,很多人以為不需要學的機器學習演算法,才是站穩腳步的基本大法! 本書就是讓你可以用Python來真正真槍實戰上手機器學習。從最基礎的資料清理、特徵工程開始,一直到資料集遺漏值的研究,包括了特徵變換、建構,降維等具有實用性的技巧,之後說明了模型是什麼,接下來全書就是各種演算法的詳解,最後還有一個難得的中文自然語言處理的
案例,不像一般機器學習的書千篇一律MNIST手寫辨識、人臉辨識這麼平凡的東西,難得有深入「機器學習」的動手書,讓你真的可以在人工智慧的領域中走的長長久久。 大集結!聚類演算法 ✪K-means 聚類 ✪系統聚類 ✪譜聚類 ✪模糊聚類 ✪密度聚類 ✪高斯混合模型聚類 ✪親和力傳播聚類 ✪BIRCH 聚類 技術重點 ✪資料探索與視覺化 ✪Python實際資料集特徵工程 ✪模型選擇和評估 ✪Ridge回歸分析、LASSO回歸分析以及Logistic回歸分析 ✪時間序列分析 ✪聚類演算法與異常值檢測 ✪決策樹、隨機森林、AdaBo

對比實數與複數神經網路之圖片分辨
為了解決Numpy softmax 的問題,作者李明學 這樣論述:
有鑑於深度學習應用層面擴大,所適用各領域不同的學習方法也日漸增加,本文以複數組成的捲積神經網路,利用基於隨機梯度下降的複數反向傳播以形成架構,使用MNIST 數據來進行實驗,透過監督訓練將每個像素分類為已知圖片類型,對比出與傳統實數神經網路之優劣。考慮到目標的標籤始終是實值,因此在輸出層進行softmax 分類之前,要計算從最後一個卷積層獲得的複矢量的大小。實驗表明,使用虛部的分類誤差表現的確比實部好,但就整體準確性而言,複數神經網路在影像分辨上的表現並沒辦法與其他新穎的神經網路相比。
