  • AI Artificial intelligence
  • Machine learning methods can be used to implement AI.

  • the learned model can be used for inference (or prediction), meaning that the model can be used to predict the output corresponding to a given input. This output can also be called an inference result (or prediction result).
  • Machine learning can include supervised learning, unsupervised learning, and reinforcement learning. Among them, unsupervised learning can also be called unsupervised learning.
  • Supervised learning uses machine learning algorithms to learn the mapping relationship between sample values and sample labels based on collected sample values and sample labels, and then expresses this learned mapping relationship using an AI model.
  • the process of training a machine learning model is the process of learning this mapping relationship.
  • sample values are input into the model to obtain the model's predicted values.

  • the learned mapping can be used to predict new sample labels.
  • the mapping relationship learned by supervised learning can include linear mappings or nonlinear mappings. Based on the type of label, the learning task can be divided into classification tasks and regression tasks.
  • Unsupervised learning uses algorithms to discover inherent patterns in collected sample values.
  • One type of unsupervised learning algorithm uses the samples themselves as supervisory signals, meaning the model learns the mapping from one sample to another. This is called self-supervised learning.
  • the model parameters are optimized by calculating the error between the model's predictions and the samples themselves.
  • Self-supervised learning can be used in signal compression and decompression recovery applications. Common algorithms include autoencoders and generative adversarial networks.
  • Reinforcement learning unlike supervised learning, is a type of algorithm that learns problem-solving strategies through interaction with the environment. Unlike supervised and unsupervised learning, reinforcement learning problems lack explicit label data for "correct" actions. Instead, the algorithm must interact with the environment to obtain reward signals from the environment, and then adjust its decision-making actions to maximize the reward signal value. For example, in downlink power control, the reinforcement learning model adjusts the downlink transmit power of each user based on the overall system throughput fed back by the wireless network, hoping to achieve higher system throughput. The goal of reinforcement learning is also to learn the mapping between environmental states and optimal (e.g., optimal) decision-making actions. However, because the labels for "correct actions" cannot be obtained in advance, network optimization cannot be achieved by calculating the error between actions and "correct actions.” Reinforcement learning training is achieved through iterative interaction with the environment.

Abstract

La présente demande concerne un procédé de communication et un appareil associé. Au cours du procédé, après l'acquisition d'une ou plusieurs données d'échantillon, un premier appareil de communication peut traiter lesdites une ou plusieurs données d'échantillon et des données de raisonnement sur la base d'un premier modèle de réseau neuronal de façon à obtenir un résultat de raisonnement qui correspond aux données de raisonnement. De cette manière, lorsqu'un appareil de communication dans un système de communication fait office de nœud de traitement de modèle, la puissance de calcul de l'appareil de communication peut être appliquée au traitement de modèles de réseau neuronal. En outre, le résultat de raisonnement obtenu par le premier appareil de communication sur la base du premier modèle de réseau neuronal est le même qu'au moins une caractéristique de données des données d'échantillon, c'est-à-dire que, sur la base d'exemples ou d'indications des données d'échantillon, le premier appareil de communication peut obtenir le résultat de raisonnement ayant au moins une caractéristique de données qui est la même que celle des données d'échantillon, et peut ajuster un raisonnement de modèle dans un scénario spécifique sur la base des données d'échantillon, ce qui permet de réduire la complexité en termes de gestion de modèles.
