About me

Andrea Rizzi studies Mathematics at University College Dublin, with a focus on AI and software engineering. He is building Inhabis, a platform for digital twins of homes, and developed Ella, a private local voice assistant. His work connects mathematical research, machine learning, and the engineering of useful systems.

Projects

  1. Inhabis landing-page image of a solar-powered cutaway home at sunrise

    Building digital twins of homes to understand, improve, and automate how they operate.

    • Matter
    • IoT
    • Embedded Systems
  2. Ella's actual 3D-printed enclosure, Raspberry Pi and connected electronics during assembly

    Ella is a fully local voice assistant for private, low-latency smart home control.

    • Local LLM
    • Deep Learning
    • PyTorch
    • Python
  3. A custom, on-device wake-word detector for Ella, using log-mel audio features and depthwise separable convolutional neural networks.

    • Keyword Spotting
    • DSCNNs
    • Log-Mel Spectrograms
    • PyTorch
  4. From eigenvalues to a persymmetric matrixThree prescribed eigenvalues connect to a matrix with rows a, b, d; c, e, b; and f, c, a. Matching entries share colours across the anti-diagonal.Inverse Eigenvalue Problemλ1λ2λ3aabbccdef

    My final-year mathematics project, exploring which eigenvalues persymmetric matrices can realise under prescribed zero and sign patterns, with symbolic verification in Mathematica.

    • Linear Algebra
    • Inverse Eigenvalues
    • Sign Patterns
    • Mathematica
