# Phi-3 Mini 4K Verbalized Rebus Solver - PEFT Adapters 🇮🇹

This model is a parameter-efficient fine-tuned version of Phi-3 Mini 4K trained for verbalized rebus solving in Italian, as part of the [release](https://huggingface.co/collections/gsarti/verbalized-rebus-clic-it-2024-66ab8f11cb04e68bdf4fb028) for our paper [Non Verbis, Sed Rebus: Large Language Models are Weak Solvers of Italian Rebuses](https://arxiv.org/abs/2408.00584). The task of verbalized rebus solving consists of converting an encrypted sequence of letters and crossword definitions into a solution phrase matching the word lengths specified in the solution key. An example is provided below.

The model was trained in 4-bit precision for 5070 steps on the verbalized subset of the [EurekaRebus](https://huggingface.co/datasets/gsarti/eureka-rebus) using QLora via [Unsloth](https://github.com/unslothai/unsloth) and [TRL](https://github.com/huggingface/trl). This repository contains PEFT-compatible adapters saved throughout training. Use the `revision=<GIT_HASH>` parameter in `from_pretrained` to load mid-training adapter checkpoints.

We also provide [a merged version of the model](https://huggingface.co/gsarti/phi3-mini-rebus-solver-fp16) and [8-bit GGUF](https://huggingface.co/gsarti/phi3-mini-rebus-solver-Q8_0-GGUF) versions of this model for analysis and local execution. 

## Using the Model

The following example shows how to perform inference using Unsloth or Transformers:

```python

# With Unsloth (efficient, requires GPU)
from unsloth import FastLanguageModel

model, tokenizer = FastLanguageModel.from_pretrained(
    model_name = "gsarti/phi3-mini-rebus-solver-adapters",
    max_seq_length = 1248,
    load_in_4bit = True,
)

# Inference
verbalized_rebus = "[Materiale espulso dai vulcani] R O [Strumento del calzolaio] [Si trovano ai lati del bacino] C I [Si ingrassano con la polenta] E I N [Contiene scorte di cibi] B [Isola in francese]"
solution_key = "1 ' 5 6 5 3 3 1 14"
template = """<s><|user|>
Risolvi gli indizi tra parentesi per ottenere una prima lettura, e usa la chiave di lettura per ottenere la soluzione del rebus.

Rebus: {rebus}
Chiave risolutiva: {key}<|end|>
<|assistant|>"""
input = template.format(rebus=verbalized_rebus, key=solution_key)
inputs = tokenizer(input, return_tensors="pt")["input_ids"]
outputs = model.generate(input_ids = inputs, max_new_tokens = 500, use_cache = True)
model_generations = tokenizer.batch_decode(outputs)
print(model_generations[0])

# Procediamo alla risoluzione del rebus passo per passo:
# - [Materiale espulso dai vulcani] = lava
# - R O = R O
# - [Strumento del calzolaio] = lesina
# - [Si trovano ai lati del bacino] = anche
# - C I = C I
# - [Si ingrassano con la polenta] = oche
# - E I N = E I N
# - [Contiene scorte di cibi] = silos
# - B = B
# - [Isola in francese] = ile
# 
# Prima lettura: lava R O lesina anche C I oche E I N silos B ile
# 
# Ora componiamo la soluzione seguendo la chiave risolutiva:
# 1 = L
# ' = '
# 5 = avaro
# 6 = lesina
# 5 = anche
# 3 = ciò
# 3 = che
# 1 = è
# 14 = insilosbile
# 
# Soluzione: L'avaro lesina anche ciò che è insilosbile
```

### Local usage with Ollama

A ready-to-use local version of this model is hosted on the [Ollama Hub](https://ollama.com/gsarti/phi3-mini-rebus-solver) and can be used as follows:

```shell
ollama run gsarti/phi3-mini-rebus-solver "Rebus: [Materiale espulso dai vulcani] R O [Strumento del calzolaio] [Si trovano ai lati del bacino] C I [Si ingrassano con la polenta] E I N [Contiene scorte di cibi] B [Isola in francese]\nChiave risolutiva: 1 ' 5 6 5 3 3 1 14"
```

## Limitations

**Lexical overfitting**: As remarked in the related publication, the model overfitted the set of definitions/answers for first pass words. As a result, words that were [explicitly witheld](https://huggingface.co/datasets/gsarti/eureka-rebus/blob/main/ood_words.txt) from the training set cause significant performance degradation when used as solutions for verbalized rebuses' definitions. You can compare model performances between [in-domain](https://huggingface.co/datasets/gsarti/eureka-rebus/blob/main/id_test.jsonl) and [out-of-domain](https://huggingface.co/datasets/gsarti/eureka-rebus/blob/main/ood_test.jsonl) test examples to verify this limitation.
