機器學習基本概念簡介（機器學習 2021）筆記

機器學習：讓機器幫我們找一個函式來解決問題。（⇔ 傳統：我們寫出函式叫機器執行） 用來解決「解決問題的函式」會複雜到人寫不出來的問題。例如：語音辨識、影像辨識⋯⋯ 基本步驟 1. 選擇 Model － 寫出帶有未知參數的函式 2. 定義 Loss：一個用來評估 model 輸出的優劣的 function 3. Optimization － 解一個最佳化問題 進一步改善 * 依照對問題的理解來更新模型 * 更強的 Model 更多模型的變形 * Hard Sigmoid * 疊更多層 Neural Network & Deep Learning * 「Deep」的意義何在？為什麼要疊很多層？ * Overfitting

How to: Recover the Nix Store volume from a Time Machine backup on macOS

When using Time Machine, the "Nix Store" volume will be backed-up just as the Recovery volume, but it won't be restored when restoring a Time Machine Backup in macOS Recovery. However, we can still manually restore the Nix Store volume from a Time Machine backup in macOS by using rsync or tmutil restore. First of all, you'll need to create the Nix Store volume and mount it to /nix if it isn't ready. On the commands below, we're using the create-darwin-volume.sh script taken from an PR to let nix installation support macOS 10.15, you can use whatever method suitable under the current era that does the same thing. Just note that it's not needed to do a multi-user Nix installation, if you've done it before in the system, again: # Create a volume for the nix store and configure it to mount at /nix. wget https://raw.githubusercontent.com/LnL7/nix/darwin-10.15-install/scripts/create-darwin-volume.sh bash create-darwin-volume.sh # The following options can be enabled to disable spotlight indexing of the volume, which might be desirable. sudo mdutil -i off /nix # Hides the "Nix Store" disk on Desktop, need to relaunch Finder to see effect.
