Prefix tuning
Prefix tuning is a parameter-efficient method for adapting large pretrained language models to new tasks by optimizing trainable continuous vectors prepended to the input, rather than fine-tuning all model parameters.
HellaSwag
HellaSwag is a benchmark dataset designed to evaluate commonsense reasoning and natural language understanding in artificial intelligence models. It presents multiple-choice questions requiring contextual inference and grounded reasoning.
ONNX
ONNX (Open Neural Network Exchange) is an open-source format for representing machine learning models. It facilitates interoperability between different AI frameworks, enabling easier deployment and optimization of models across various platforms.
Boltzmann machine
A Boltzmann machine is a type of stochastic recurrent neural network that can learn a probability distribution over its set of inputs.
Silero (speech recognition and VAD)
Silero is an open-source toolkit that provides speech recognition and voice activity detection (VAD) capabilities. It is designed to offer efficient, high-quality models for transcribing spoken language and detecting speech segments within audio streams.
Quantization (neural networks)
Quantization in neural networks is the process of reducing the precision of the numbers used to represent model parameters and activations, typically to improve computational efficiency and reduce memory usage. It enables deployment of neural networks on resource-constrained devices by approximating floating-point values with lower-bit representations, often with minimal impact on accuracy.
Wav2Lip (lip synchronization)
Wav2Lip is a deep learning-based model designed for accurate lip synchronization in videos, allowing realistic matching of lip movements to any speech audio input. It generates lip movements that closely correspond to the spoken words, improving the quality of dubbed videos and enabling applications in multimedia and communication.
