### Load and use RNNMetricLearner model

Source: https://github.com/zouharvi/pwesuite/blob/master/README.md

Example of loading the rnn_metric_learning_token_orth model, preprocessing data, and performing inference with batching.

```python
from models.metric_learning.model import RNNMetricLearner
from models.metric_learning.preprocessor import preprocess_dataset_foreign
from main.utils import load_multi_data
import torch
import tqdm
import math

data = load_multi_data(purpose_key="all")
data = preprocess_dataset_foreign(
  [
    {"token_ort": "Hello", "token_ipa": None},
    {"token_ort": "what", "token_ipa": None},
    {"token_ort": "is", "token_ipa": None},
    {"token_ort": "pwesuite", "token_ipa": None},
  ],
  features="token_ort"
)

model = RNNMetricLearner(
    dimension=300,
    feature_size=data[0][0].shape[1],
)
model.load_state_dict(torch.load("computed/models/rnn_metric_learning_token_orth_all.pt"))

# some cheap paralelization
BATCH_SIZE = 32
data_out = []
for i in tqdm.tqdm(range(math.ceil(len(data) / BATCH_SIZE))):
    batch = [f for f, _ in data[i * BATCH_SIZE:(i + 1) * BATCH_SIZE]]
    data_out += list(
        model.forward(batch).detach().cpu().numpy()
    )

assert len(data) == len(data_out)
assert all([len(x) == 300 for x in data_out])
```

### Get feature names from CountVectorizer

Source: https://github.com/zouharvi/pwesuite/blob/master/demo.ipynb

Retrieves the feature names (character n-grams) learned by the fitted CountVectorizer model.

```python
model.get_feature_names_out()
```

--------------------------------

### Run evaluation scripts

Source: https://github.com/zouharvi/pwesuite/blob/master/README.md

Execute the evaluation suite using the provided CLI scripts after saving embeddings as Pickle or NPZ files.

```bash
./suite_evaluation/eval_all.py --embd your_embd.pkl
```

```bash
./suite_evaluation/eval_{correlations,human_similarity,retrieval,analogy,rhyme,cognate}.py
```

--------------------------------

### Load PWESuite evaluation dataset

Source: https://github.com/zouharvi/pwesuite/blob/master/demo.ipynb

Loads the 'zouharvi/pwesuite-eval' dataset from Hugging Face using the datasets library. The split is set to 'train'. The download progress is shown in the output.

```python
import datasets
data = datasets.load_dataset("zouharvi/pwesuite-eval", split="train")
```

--------------------------------

### Replicate Dataset Script

Source: https://github.com/zouharvi/pwesuite/blob/master/README.md

Execute the provided shell script to replicate the dataset locally on Linux or MacOS.

```bash
./create_dataset/all.sh
```

--------------------------------

### Run PWESuite evaluation on saved embeddings

Source: https://github.com/zouharvi/pwesuite/blob/master/demo.ipynb

Runs the PWESuite evaluation script (eval_all.py) with the saved embedding file 'embd.npy'. The output shows loading of datasets, progress bars, and final scores for human similarity, correlation, retrieval, analogy, rhyme, and cognate tasks, with an overall score of 0.6121.

```bash
!python3 ./suite_evaluation/eval_all.py --embd embd.npy
```

--------------------------------

### Extract character n-gram features with CountVectorizer

Source: https://github.com/zouharvi/pwesuite/blob/master/demo.ipynb

Creates a CountVectorizer that extracts character n-grams (1-2) with a maximum of 256 features from the 'token_ipa' field of the dataset. The fit_transform call produces a sparse matrix of embeddings.

```python
from sklearn.feature_extraction.text import CountVectorizer

model = CountVectorizer(max_features=256, analyzer="char", ngram_range=(1, 2))
embd = model.fit_transform([x["token_ipa"] for x in data])
```

--------------------------------

### Save embedding matrix to .npy file

Source: https://github.com/zouharvi/pwesuite/blob/master/demo.ipynb

Saves the sparse embedding matrix 'embd' as a dense numpy array to the file 'embd.npy' using np.save. This file is later used as input to the evaluation script.

```python
import numpy as np
np.save("embd", embd.toarray())
```

--------------------------------

### Check embedding matrix shape

Source: https://github.com/zouharvi/pwesuite/blob/master/demo.ipynb

Displays the shape of the embedding matrix 'embd'. The output shows (1738496, 256), indicating 1,738,496 rows and 256 columns.

```python
embd.shape
```
