Happy and motivated to be a finalist in the Polkadot Hackathon 2024 Singapore to build a new ecosystem on this great infrastructure. See you in Singapore. @AraucoChain

Hoy en un semáforo de Puente alto, se nos acercó al auto un caballero (diría 60-70 años) muy educado a darnos esta tarjeta, era profesor y ofrecía clases. Compartir ☺️

I am building a voice agent to find and summarize news using ElevenLabs for the interaction and Firecrawl to find specific news and websites with scraping. Here is the code: github.com/nescampos/echo… In the next post, a full video about how it works (and some fixes to the code).

Here is the project if you want to check: app.zerve.ai/notebook/c44d0…

Also, thanks to the agentic features, I could create a plan with actions to approach users (with the possibility to churn) and try to retain them. It was very easy and simple to interact, where my focus was to define the problem very well and specify the right instructions 🧵

I have created my first project with @Zerve_AI. This project explores user behavior on the platform and builds a churn model. In a few steps, by chatting with the agent, I got a full notebook of details and analysis. 🧵👇

At FinMatrix, there's no single owner. Miners compete to offer the best personalized investment strategy. How do we achieve this? ✅ Real-time market data analysis. ✅ Specialized financial language models. ✅ Portfolio optimization under real-time risk. 👇

I came up with the idea for FinMatrix, a new subnet on Bittensor for the Bittensor Ideathon by @HackQuest_ In short, the focus is on democratizing global "Alpha" through decentralized AI. 🧵👇

5/5) Here's the LoRA model if you want to explore it: modelscope.ai/models/nescamp…

4/5) The focus is on businesses like restaurants that want to display photos, but constantly taking them generates monetary costs and wasted time. What better than a customized model to do it? Here are 3 more images generated by the model.

1/5) Like many others, I decided to participate in the Qwen-Image LoRA Training Competition. And you can too: modelscope.ai/active/qwenima… What did I do? 🧵 @ModelScope2022 @Alibaba_Qwen @Ali_TongyiLab #HappyQwensday #QwenImageLora
