finalfusion-utils

Introduction

finalfusion-utils is a Rust crate offering various functionalities to process and query embeddings. finalfusion-utils supports conversion between different formats, quantization of embedding matrices, similarity and analogy queries as well as evaluation on analogy datasets.

Installation

Using cargo

finalfusion-utils can be installed using an up-to-date Rust toolchain, which can be installed with rustup.

With a valid Rust toolchain, the crate is most easily installed through cargo:

~~~shell $ cargo install finalfusion-utils ~~~

Using Nix

The development version of finalfusion-utils can be directly installed from its repository using the Nix package manager. To install the current version from the master branch into your user profile:

bash $ nix-env -i \ -f https://github.com/finalfusion/finalfusion-utils/tarball/master

To install the latest release version of finalfusion-utils, we recommend you to use the finalfusion package set. To install the current release version into your user profile:

bash nix-env -i \ -f https://github.com/finalfusion/nix-packages/tarball/master \ -A finalfusion-utils

You can get prebuilt Linux/macOS binaries using the finalfusion Cachix cache:

```bash

If you haven't installed Cachix yet:

$ nix-env -iA cachix -f https://cachix.org/api/v1/install $ cachix use finalfusion ```

Building from source

finalfusion-utils can also be built from source, after cloning this repository execute the following command in the directory to find the exectuable under target/release/finalfusion:

~~~shell $ cargo build --release ~~~

Usage

finalfusion-utils is built as a single binary, the different functionality is invoked through subcommands:

Converting embeddings

~~~shell

Convert embeddings in fastText format to finalfusion

$ finalfusion convert -f fasttext -t finalfusion \ embeddings.bin embeddings.fifu

Convert embeddings in word2vec format to finalfusion

$ finalfusion convert -f word2vec -t finalfusion \ embeddings.w2v embeddings.fifu

Print help with all supported combinations:

$ finalfusion convert --help ~~~

Quantizing an embedding matrix

~~~shell

Quantize embeddings in finalfusion format with a

single attempt through product quantization

$ finalfusion quantize -f finalfusion -q pq -a 1 \ embeddings.pq ~~~

Analogy and similarity queries

~~~ shell

Get the 15 nearest neighbours of "Tübingen" for

embeddings in finalfusion format.

$ finalfusion similar -f finalfusion -k 15 \ embeddings.fifu

Get the 5 best answers for the analogy query

"Berlin" is to "Deutschland" as "Amsterdam" to:

$ finalfusion analogy -f finalfusion -k 5 \ Berlin Deutschland Amsterdam embeddings.fifu ~~~

Evaluation on analogy datasets

~~~shell

Evaluate embeddings on some analogy dataset

$ finalfusion compute-accuracy embeddings.fifu \ analogies.txt ~~~

Dump metadata

~~~shell

Dump optionally stored metadata and store in

metadata.txt, only supported for finalfusion

format

$ finalfusion metadata embeddings.fifu \

metadata.txt ~~~

Convert Bucket Vocab to Explicit Vocab

~~~shell

Converts a hash-bucket based subword vocab to

one with explicitly stored n-grams.

$ finalfusion bucket-to-explicit buckets.fifu \ explicit.fifu ~~~

Print completion script

~~~shell

Print completion script for zsh

$ finalfusion completions zsh ~~~
