Data Scientist · Machine Learning Engineer

Turning data into decisions.

I design, build, and deploy machine learning solutions — from computer vision for public health to RL research and climate-focused analytics. I care about clarity, reliability, and measurable impact.

About

Hi, I’m Fenosoa — I build reliable ML systems from idea to impact.

I’m a Data Scientist and Machine Learning Engineer focusing on computer vision, sequence modeling, and MLOps. I care about reproducibility, clean UX for data tools, and delivering models that actually make decisions better.

What I do

I design ML workflows end‑to‑end: framing the problem, building robust datasets, prototyping, evaluating with the right metrics, and shipping simple interfaces teams can use.

  • Computer vision (classification, segmentation, detection)
  • Sequence modeling & forecasting
  • Reinforcement learning research
  • MLOps & data platform plumbing

How I work

Clear specs, tight feedback loops, and reproducible code. I prefer small, testable steps and dashboards that make model behavior obvious.

Featured research · CosMAP

Making high-dimensional structure visible.

I developed CosMAP (Contrastive Manifold Approximation and Projection) which is a new graph-based unsupervised dimensionality-reduction method for producing faithful and interpretable embeddings of sparse, noisy data.

On MNIST, shown here, CosMAP organizes 70,000 handwritten-digit samples with 784 features into a two-dimensional map. Each point is one image; color indicates its true digit label. Compact neighborhoods and distinct regions make both local relationships and the overall class structure easier to inspect.

Result: On the MNIST and USPS benchmarks, CosMAP yielded the most interpretable two-dimensional cluster structure among the evaluated methods, with LocalMAP providing the closest competing performance. Its embeddings produced compact, well-separated digit populations while maintaining a readable global organization.

Comparative evaluation: CosMAP was evaluated against PaCMAP, UMAP, LocalMAP, t‑SNE, TriMAP, PHATE, PCA, h‑NNE, InfoNCE‑t‑SNE, Neg‑t‑SNE, and NCVis across diverse image, single-cell RNA-seq, and genealogical datasets.

The method combines cosine-similarity neighborhoods with temperature-normalized contrastive affinities, an attractive–repulsive objective, and a two-phase refinement strategy.
