+## Model `bertin_base_sentiment_analysis_es`
+
+### **A finetuned model for Sentiment analysis in Spanish**
+
+This model was trained using Amazon SageMaker and the new Hugging Face Deep Learning container,
+The base model is **Bertin base** which is a RoBERTa-base model pre-trained  on the Spanish portion of mC4 using Flax.
+It was trained by the Bertin Project.[Link to base model](https://huggingface.co/bertin-project/bertin-roberta-base-spanish)

+
+## Dataset
+The dataset is a collection of movie reviews in Spanish, about 50,000 reviews. The dataset is balanced and provides every review in english, in spanish and the label in both languages. 
+
+Sizes of datasets:
+- Train dataset: 42,500
+- Validation dataset: 3,750
+- Test dataset: 3,750
+
+## Intended uses & limitations
+
+This model is intented for Sentiment Analysis for spanish corpus and finetuned specially for movie reviews but it can be applied to other kind of reviews.

+### Usage for Sentiment Analysis
+
+```python
+import torch
+from transformers import AutoTokenizer, AutoModelForSequenceClassification
+
+tokenizer = AutoTokenizer.from_pretrained("edumunozsala/bertin_base_sentiment_analysis_es")
+model = AutoModelForSequenceClassification.from_pretrained("edumunozsala/bertin_base_sentiment_analysis_es")
+
+text ="Se trata de una película interesante, con un solido argumento y un gran interpretación de su actor principal"
+
+input_ids = torch.tensor(tokenizer.encode(text)).unsqueeze(0)
+outputs = model(input_ids)
+output = outputs.logits.argmax(1)
+```
