Phi-3 Mini 4K Verbalized Rebus Solver 🇮🇹
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 for our paper Non Verbis, Sed Rebus: Large Language Models are Weak Solvers of Italian Rebuses. 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 using QLora via Unsloth and TRL. This version has merged adapter weights in half precision, enabling out-of-the-box for usage with the transformers library.
We also provide adapter checkpoints through training and 8-bit 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:
# With Unsloth (efficient, requires GPU)
from unsloth import FastLanguageModel
model, tokenizer = FastLanguageModel.from_pretrained(
model_name = "gsarti/phi3-mini-rebus-solver-fp16",
max_seq_length = 1248,
load_in_4bit = True,
)
# Or with Transformers
from transformers import AutoTokenizer, AutoModelForCausalLM
tokenizer = AutoTokenizer.from_pretrained("gsarti/phi3-mini-rebus-solver-fp16")
model = AutoModelForCausalLM.from_pretrained("gsarti/phi3-mini-rebus-solver-fp16")
# 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
See the official code release for more examples.
Local usage with Ollama
A ready-to-use local version of this model is hosted on the Ollama Hub and can be used as follows:
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 from the training set cause significant performance degradation when used as solutions for verbalized rebuses' definitions. You can compare model performances between in-domain and out-of-domain test examples to verify this limitation.
