Tensor Extraction of Latent Features (T-ELF)

ℹ️ Documentation   📙 Examples   📃 Publications   🔗 Website

T-ELF is one of the machine learning software packages developed as part of the R&D 100 winning SmartTensors AI project at Los Alamos National Laboratory (LANL). T-ELF presents an array of customizable software solutions crafted for analysis of datasets. Acting as a comprehensive toolbox, T-ELF specializes in data pre-processing, extraction of latent features, and structuring results to facilitate informed decision-making. Leveraging high-performance computing and cutting-edge GPU architectures, our toolbox is optimized for analyzing large datasets from diverse set of problems.

Central to T-ELF's core capabilities lie non-negative matrix and tensor factorization solutions for discovering multi-faceted hidden details in data, featuring automated model determination facilitating the estimation of latent factors or rank. This pivotal functionality ensures precise data modeling and the extraction of concealed patterns. Additionally, our software suite incorporates cutting-edge modules for both pre-processing and post-processing of data, tailored for diverse tasks including text mining, Natural Language Processing, and robust tools for matrix and tensor analysis and construction.

T-ELF's adaptability spans across a multitude of disciplines, positioning it as a robust AI and data analytics solution. Its proven efficacy extends across various fields such as Large-scale Text Mining, High Performance Computing, Computer Security, Applied Mathematics, Dynamic Networks and Ranking, Biology, Material Science, Medicine, Chemistry, Data Compression, Climate Studies, Relational Databases, Data Privacy, Economy, and Agriculture.

Installation

Step 1: Install Poetry to your system

This step is optional. Use Pip or Conda if Poetry is not avaiable.

Step 2: Install the Library

Option 1: Install via Poetry or Pip

conda create --name TELF python=3.11.10
source activate TELF # or <conda activate TELF>
poetry install # or <pip install .>

Option 2: Install via Conda

git clone https://gitlab.lanl.gov/maksim/telf_internal
cd telf_internal
conda env create --file environment_gpu.yml # use <conda env create --file environment_cpu.yml> for CPU only
conda activate TELF_conda
conda develop .

Step 3: Post-installation Dependencies

Next, we need to install the optional and additional dependencies. These include optional dependencies for GPU and HPC capabilities, as well as required dependencies like the SpaCy language models. To view all available options, please run:

python post_install.py --help

Install the additional dependencies:

python post_install.py # use the following, for example, for GPU system: <python post_install.py --gpu>
