Risk and Mitigation

1. Risk: Bias in the Training Data

If the data used to train the sentiment analysis model is biased, the model's predictions could be skewed and not representative of diverse real-world situations.

Mitigation:

  - Use a diverse and comprehensive dataset that captures various sentiments across different contexts and demographics.

  - Employ techniques like data augmentation to create synthetic training examples and diversify the training set.

  - Continuously review and audit model predictions and refine the training dataset accordingly.

2. Risk: Overfitting

The model might perform exceptionally well on the training data but fail to generalize on unseen data.

Mitigation:

  - Utilize techniques like cross-validation to make sure the model's performance is consistent across different subsets of the data.

  - Employ regularization techniques.

  - Use dropout in neural network architectures.

3. Risk: Misinterpretation of Complex Sentiments Sentiment is multifaceted and can be subtle; AI models may not be able to capture sarcasm, irony, or mixed emotions.

Mitigation:

  - Curate a dataset specifically targeting complex sentiments for training.

  - Use ensemble models or hybrid models that combine rule-based and machine learning methods.

  - Continuously gather feedback from real-world deployments and refine the model.

4. Risk: High Computational Costs

Training deep learning models for sentiment analysis can be computationally expensive.

Mitigation:

  - Explore transfer learning, where a pre-trained model is fine-tuned for the specific sentiment analysis task, reducing the training time and resources.

  - Utilize cloud-based services that offer scalable computational resources.

5. Risk: Data Privacy Concerns

Using real-world data might breach privacy regulations if not handled properly.

Mitigation:

  - Ensure all training data is anonymized and stripped of personally identifiable information.

  - Use synthetic or simulated data where possible.

  - Comply with local data protection regulations, such as Brazil's LGPD.

Voluntary Revenue

We will onboard the service on the platform. If the service crosses the threshold of $1000, revenue per month, 5% of the additional revenue will be fed back into the SNET/DeepFunding wallets. This condition will remain valid for 5 years after first onboarding the service and will be applicable to this service or any subsequent iteration of this service on the platform.

Open Source

Celeste is not open sourced yet, but we intend to open source our APIs as we develop our own AI models, supporting the expansion of AI technology in Portuguese, Spanish, Italian, French and Romanian languages.

Q&A

Learn more about our proposal based on SNET's community concerns:

Data Privacy - Legal compliance is one of our top priorities, especially in Brazil, where consumer data privacy regulations have been implemented over the past years. We have a team of three lawyers with expertise in data privacy, LGPD, taxation, and blockchain technology assisting our operations. We believe our counsel team is able to provide adequate support for continuous compliance as AI regulations evolve. Additionally, all information will be used exclusively to set up the parameters for training the models. The training will be done in a restricted environment with data that is already anonymized (by the platform by default). Our platform was created with privacy at its core, so the chances to leak any sensitive information are really low.

Potential Bias - Our platform itself is a datasource of information since users can review their transcription content, meaning our learning process includes human reinforcement as a core component, therefore improving model training.  We also plan to use journalistic data sources, such as data, audio, text and videos that can serve as a complementary resource of pre-classified data. We have two journalists on the team to provide technical support with the process.  Further, the model can be optimized through cross-validation with text-based sentiment analysis from transcriptions, which usually offers a broader level of accuracy on sentiment analysis. 

Cultural Relevance - For this sentiment analysis model, we would work with a diverse and segmented database, including different "variants" of Portuguese, covering regional and cultural expressions/nuances. We believe community feedback is also crucial to keep the model culturally relevant and accurate, so we'd like to incorporate feedback from our users and the SNET community. We just went live in beta 8 weeks ago (with over 2k users so far), so we want to foster community feedback not only for refining our models, but for marketing engagement as well.
