FlyHash vs SimHash Demo

FlyHash vs SimHash Demo

An interactive browser demo that compares FlyHash and SimHash for retrieving items, built to accompany a paper on FlyHash for LLM agent memory. For researchers and developers building agent memory.

About

What it is: FlyHash vs SimHash Demo is an interactive browser demo that compares two hashing methods for retrieving similar items. It accompanies a paper on using FlyHash as memory for LLM agents. It is a static page, so nothing runs on a server.

Who it suits: It suits people who build memory for LLM agents and want to see how a FlyHash approach compares with SimHash.

Title: Who might use this demo
Industry | Who uses it | How they use it | Example
Agent development | Engineers | Judge hashing methods for agent memory retrieval | Run the same lookup with both methods
Research | Researchers | Explore the paper's idea hands on | Read the demo beside the paper
Education | Students | See how two hashing schemes differ | Compare what each one retrieves

If you need a ready-made memory library for production, you can skip it, since this is a demo.

Where to use it: You can use it online or open its files on your own computer.

• Web browser: the Space's page on Hugging Face, with nothing to install
• Windows, macOS or Linux: the downloaded files, opened in a browser

Title: What the demo is good for
Use case | Who | What they get back
Compare retrieval methods | Engineers | A side by side view of FlyHash and SimHash results
Follow the paper | Researchers | An interactive companion to the paper
Teach hashing | Instructors | A visual to show how two methods differ

How to set it up: The hosted page needs nothing. To get the files you need Python and pip.

• Python, with pip
• Any web browser

1. Install the huggingface_hub package.
2. Download the Space's files into a folder.
3. Move into that folder.
4. Open index.html in a web browser.

pip install -U huggingface_hub
hf download pranamhan/flyhash-agent-memory-demo --repo-type space --local-dir flyhash-agent-memory-demo
cd flyhash-agent-memory-demo

How to use it: Open the Space online, or open index.html from your downloaded folder. Then use the controls on the page to run a retrieval and compare what the two methods return.

Title: The files you will meet
Tool | What it does
index.html | The interactive demo page
style.css | The styles that shape how the page looks
README.md | The Space's short notes, including pointers to the paper

Example: You open the demo and run one retrieval through both methods. The page shows what FlyHash finds and what SimHash finds, so you can compare them.

For newcomers and experts: If you are new to this, think of both methods as ways to boil an item down to a short code so similar items can be found quickly. Try one retrieval and compare the two results.

If you know the field, the demo is the interactive side of an empirical validation of FlyHash for LLM agent memory. The notes point to the paper, to code and a dataset in a separate repository, and to an archive.

Open the demo
Run a retrieval
FlyHash and SimHash each respond
You compare what they return

Good to know: The Space's notes are short, so the paper is the place for the full method.

• Static page: plain HTML and CSS, with no server code
• Paper: the readme points to the paper, to code and a dataset, and to an archive
• License: mit
• Cost to run: none named
• Data it reaches: nothing beyond its own files is named in the notes
• Not for: use as a production memory store
