The route definition

post "/sandhi/analyze", to: "sandhi_analyses#analyze"

automatically includes an optional :format segment, so both

/sandhi/analyze      # no explicit format
/sandhi/analyze.json # JSON extension

match the same sandhi_analyses#analyze action.

user:

found the source code of many AI papers hard to read, partially because the authors are not in the mindset of software engineers, therefore the code is not aligned to software engineering best practices. How to solve this problem? I want to understand the code so that I can master the concetps in the papers more thourougly through code reading

assistant:

Reading and fully understanding research code can be challenging, especially when code bases don’t follow traditional software engineering (SE) best practices. Here are some suggestions for getting more out of (often messy) AI research code:

1. Organize the Context Before Diving In • Read the paper thoroughly. Make note of the key steps in the algorithm, the architectural components, and the logic flow. Then map these steps to the filenames, modules, and functions you see in the code.

In Emacs, the minibuffer is typically used for single-line input, so pressing RET (Enter) usually submits the input. However, if you need to input a line break (newline) in the minibuffer, you can do so by using the following methods: Method 1: Use C-q C-j

Press C-q (quoted-insert), followed by C-j (newline).

This inserts a literal newline character into the minibuffer.

Method 2: Use C-o

Press C-o (open-line), which inserts a newline and moves the cursor to the new line.

The reward model equation represents the negative log-likelihood loss for training the reward model $r_{\phi}$:

1. $r_{\phi}(x, y)$ is the reward model with parameters $\phi$.

2. $(x, y_w, y_l)$ is a tuple from the dataset $\mathcal{D}$, where:

   • $x$ is the input
   • $y_w$ is the preferred output
   • $y_l$ is the less preferred output

3. $\sigma(z) = \frac{1}{1+e^{-z}}$ is the logistic function.

Below is a working example of how to create (1) a simple AppleScript application that registers a custom URL scheme, and (2) links that open a given PDF at a given page in Skim.

────────────────────────────────────────────────────────

1. Create the AppleScript ────────────────────────────────────────────────────────
2. Open “Script Editor” (in /Applications/Utilities).
3. Create a new document and paste this script:

-- This handler is called when a URL with the scheme "skimpdf://" is opened.
