This project is a comprehensive collection of educational examples and reference implementations for building vision and language models using PyTorch. It serves as a deep learning tutorial covering the end-to-end process of developing neural networks, from initial architecture definition to final production deployment. The repository provides detailed guides on implementing a wide range of domain-specific models, including convolutional neural networks for object detection and segmentation, as well as transformer and recurrent architectures for natural language processing. It emphasizes gene
Defines the order and frequency of sample selection to manage class imbalances during training.
imbalanced-learn is a dataset balancing framework and Python machine learning extension designed to resample training data and reduce the impact of class imbalance. It provides a toolkit of algorithms for adjusting class distributions to improve model performance on minority class prediction. As a scikit-learn resampling library, it extends the ecosystem with specialized tools for balancing datasets through over-sampling and under-sampling techniques. This allows for the correction of skewed class proportions to reduce model bias toward the majority class. The library implements the scikit-l
Applies sampling techniques to datasets with significant class differences to increase model accuracy.
PyTorch Metric Learning is an open-source library for training neural networks to produce similarity-preserving embedding spaces. It provides a modular framework where interchangeable loss functions, mining strategies, and evaluation tools can be composed to learn representations that map similar items to nearby points and dissimilar items to distant points in the embedding space. The library distinguishes itself through a highly configurable architecture that separates concerns across several interchangeable components. Users can assemble custom loss functions from pluggable distance metrics
Implements hierarchical sampling strategies that respect nested label structures during batch construction for metric learning.
Acest proiect este o resursă educațională cuprinzătoare și un curs pentru construirea de rețele neuronale folosind PyTorch. Acoperă elementele fundamentale ale deep learning-ului, inclusiv manipularea tensorilor, diferențierea automată și construcția componentelor modulare de rețele neuronale. Repository-ul servește drept ghid tehnic pentru mai multe domenii specializate. Oferă detalii de implementare pentru sarcini de computer vision, cum ar fi clasificarea imaginilor, detecția obiectelor și segmentarea semantică, precum și fluxuri de lucru de procesare a limbajului natural (NLP) care implică transformatoare, rețele recurente și modele generative. În plus, include o referință pentru AI generativ, concentrându-se în mod specific pe sinteza de imagini prin modele de difuzie și rețele adversariale.
