Target Recognition Based on Deep Learning
The advantages of deep learning in target recognition include automatic feature extraction, powerful expression ability, large-scale data-driven and transfer learning.
1, automatic feature extraction
Traditional target recognition methods usually need to design feature extractors manually, while deep learning models can automatically learn the feature representation of targets through multi-layer neural networks, reducing manual intervention.
2. Strong expressive ability
The deep learning model has the ability of multi-level nonlinear transformation, and can learn more complex and abstract feature representations, thus improving the accuracy and robustness of target recognition.
3. Large-scale data drive
The deep learning model has a strong learning ability for large-scale labeled data, and the performance of the model can be improved through continuous iterative training.
4. Transfer learning
The deep learning model can apply the learned knowledge to new tasks through transfer learning, thus reducing the training time and data requirements.
At present, target recognition based on deep learning has made remarkable achievements in many fields, such as face recognition, object detection, pedestrian recognition and so on. Among them, Convolutional Neural Network (CNN) is one of the most commonly used deep learning models. It extracts features from images through the combination of convolution layer, pool layer and fully connected layer, and classifies them by softmax function.
The concept of deep learning
Deep learning is an important branch of artificial intelligence. By simulating the connection and information transmission mechanism between human brain neurons, it constructs a neural network model with multiple hidden layers, and learns the internal laws and representation levels of sample data. This technology can be used to deal with complex data and tasks, such as image recognition, text generation, natural language processing and so on.
The core concept of deep learning comes from the research of artificial neural network, especially those multilayer perceptrons with multiple hidden layers. These networks combine low-level features to form a more abstract high-level representation attribute category or feature, thus discovering the distributed feature representation of data.
Deep learning is widely used in many fields, including but not limited to image, voice, autonomous driving and medical treatment. Although deep learning has made remarkable achievements in many aspects, it also faces some challenges, such as the need for a large number of labeled data, the consumption of computing resources and poor model interpretation.
