ask: what is a convolutional neural network Answer: Convolutional Neural Network (CNN) is a type of artificial neural network that is primarily used for image and video recognition tasks. It is designed to process data through multiple layers of arrays, commonly known as convolutional layers, which learn hierarchical representations of the input data. The layers apply filters to the input data to detect various features, such as edges, textures, and shapes, which are then used to classify the input data into various classes. 根據上面的說法，我們可以知道CNN是一種人工的神經網路，為一種類神經網路，主要用在影像與影片辨識的任務。早期的類神經網路2個層的任何節點都有連結，如上圖，而CNN的設計為2個層間的節點不一定要有連結。設計的方式可比類神經網路更為多層的陣列，這些很多層的陣列稱為convolutional layers，這些多層的陣列可以學習上層的輸入資料。可以使用一些filter將上層輸入進來的資料解析，如邊緣、紋理、形狀，接著再將這些輸入的資料分為許多的類別。 一種Convolutional Neural Network辨識的範例 如上圖，輸入為圖片，輸入層為最左邊，通常有中間稱為隱藏層，可以有多層，最後再分類，可以分類輸入的照片為汽車、卡車、休旅車...等。這種作法僅使用多個圖片資料輸入，就可在相同的程式中(Convolutional neural network)訓練出很好的辨識結果。 通常只要輸入的資料夠多，CNN就能辨識成功，效果很好，可以應付比較多變的環境也有不錯的辨識效果。如晴天與雨天的車輛辨識，使用傳統演算法可能需要2個或多個

 https://chat.openai.com/chat now we can test chatgpt in typing something: chatGPT uses AI or deep learning to train cyber data, and lets humans use natural language to answer human questions, the process like a chatting APP. the news said chatgpt can write article too. ask: high dividend stock chatgpt answer: A high dividend stock is a stock that pays a substantial amount of dividend income relative to its stock price. Some companies that are known for paying high dividends include: Johnson & Johnson Procter & Gamble Coca-Cola Verizon Communications AT&T It's important to note that high dividends are not a guarantee and can change over time, so it's always a good idea to do thorough research and consult with a financial advisor before making investment decisions. Additionally, high dividend yields can sometimes be a sign of a stock that is underperforming, so it's important to consider a company's financial health, earnings growth potential, and other facto

 最近幫主管操作報稅軟體，需要填寫上期留抵稅額，所以寫篇教學，怕之後忘記。 1. 在pc上面的留抵稅額要修改，修改方式如下： 先按步驟7的申報書登入。一般公司可選401報表。 選1「稅額計算」頁簽後，在2的108地方填寫留底稅額。 這樣之後資料應該會自己代出來。 這樣401報表就完成了。
