+# Gemma-2 2B Verbalized Rebus Solver - PEFT Adapters 🇮🇹
+
+This model is a parameter-efficient fine-tuned version of Gemma-2 2B 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 [FP16 merged](https://huggingface.co/gsarti/gemma-2-2b-rebus-solver-fp16) and [8-bit GGUF](https://huggingface.co/gsarti/gsarti/gemma-2-2b-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:
+
+```python
+
+# With Unsloth (efficient, requires GPU)
+from unsloth import FastLanguageModel
+
+model, tokenizer = FastLanguageModel.from_pretrained(
+    model_name = "gsarti/gemma-2-2b-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 = """<bos><start_of_turn>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_of_turn>
+<start_of_turn>model"""
+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] = dispensa
+# - 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 = indispensabile
+# 
+# Soluzione: L'avaro lesina anche ciò che è indispensabile
+```

+
+### Local usage with Ollama
+
+A ready-to-use local version of this model is hosted on the [Ollama Hub](https://ollama.com/gsarti/gemma2-2b-rebus-solver) and can be used as follows:
+
+```shell
+ollama run gsarti/gemma2-2b-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.
