Neural Networks (AI) project

Current focus in my research is training BERT and GPT LLMs on your ownsynthetic + real Dataset, and LoRA fine-tuning of various Heads. This isPython PyTorch + Hugging Face Transformers activity.
  • I am writing Neural Networks framework in Julia to:
    • Make very precise Time Series next value predictions. Exact numberprediction
    • Make very precise Classification
    • Accuracy like 98% - 99%
  • This is pure research project
  • Julia Transformers fit in here too with potential to create Transformers 2.0architecture. First, learning existing Transformers, and rewriting low levelneural networks basics. Then next gen framework for Transformers in Julia.
  • I could be extremely useful in parallel processes programming for neuralnetworks training and inference. Tree-like neural networks architectures, multi-modal neural networks. Regression, Graph Neural Networks. Non-sequentialNeural Networks.
Plus, strong Cloud and Kubernetes backends programming skills.

  • It usuallyends with the template to kick start the projects with particular technology set.
  • From all Node.js frameworks I used in 3+ years, NestJS seems to be the best.
  • Probably, because I spent 9 years with Java and Kotlin 
  • It is Java worldclone, noticeably.
  • Golang is different, because it is functional language. 
  • Golang wins them all.
  • Probably Rust even more.
