M.Sc. in Computer Science

My thesis explores state-of-the-art neural network pruning techniques, empirically examining how pruned models converge to various theoretical bounds within controlled environments. Additionally, I assessed the performance and efficiency of these pruned networks in comparison to their fully dense counterparts.

Machine Learning Engineer

Built the first proof-of-concept demo that generated automated reports using LLMs (closed and open-source) for a major mining company. Data varied from administrative, legal and operational documents which in turn needed to be parsed and structured. Developed specific prompt engineering to maximize quality depending on the document type and model used. Public version not available. Fine-tuned 1 oss model but to no avail.
Stack revolved around: Vector Database (Chroma), LangChain, Pydantic, HF and OpenAI, and other dashboards tools.

Machine Learning Engineer Intern

Studied the use of embeddings of protein language models to predict protein stability. My work provided baseline results against which the team was able to benchmark their models.
Involved the use of: Pytorch, Protein-specific LLMs and traditional classifiers, Procesing of protein and amino acid sequences.

Data Engineer

Analyzed satellite, oceanographic and industrial data in order to detect, prevent harmful algal blooms. Obtained, processed and stored data from different sources to build a recommendation system for mining companies to improve the efficiency of their desalination plants. Data was stored in GCS and processed using BigQuery.

Understanding Encoder-Decoder Structures in Machine Learning Using Information Measures [Submitted and in Review]

Linked information-theoretical concepts to understand effects of encoder-decoder structures in ML architectures. By decomposing the effects of encoder and decoder in a separate manner, we provided theoretical bounds to the performance of models in terms of information measures.
I specifically led the efforts into empirically proving the theoretical results.

Investigating Climate Downscaling with Generative Super Resolution methods

Worked on the application of generative models to downscaling problems in climate science. We performed an overview of the differences between different models. In particular, we studied the difficulties in training and the transferability of established super-resolution models.

ProjectX 2020: Machine Learning Research Competition: Climate Change

Represented U.Chile in a three-month-long ML research competition, hosted by U.Toronto. The focus of our research went into studying and developing models that could be used for landslide's early warning systems. I particularly worked on data processing and model development. Mentored by three professors: Felipe Tobar (U.Chile), Jorge Perez (U.Chile) and Apurva Narayan(U. Vancouver)
