研究目的
To develop and evaluate a convolutional neural network model for enhancing image classification accuracy in data science applications.
研究成果
The CNN model achieved high accuracy in image classification tasks, demonstrating its effectiveness for data science applications. Future work could explore transfer learning and data augmentation to improve robustness.
研究不足
The model's performance may be limited by the size and diversity of the dataset. Computational resources required for training large models can be a constraint. Generalization to other image types may require additional tuning.
1：Experimental Design and Method Selection:
A CNN architecture was designed and implemented using TensorFlow and Keras frameworks. The method involved training the model on a dataset of labeled images.
2：Sample Selection and Data Sources:
The CIFAR-10 dataset was used, consisting of 60,000 32x32 color images in 10 classes, with 50,000 training images and 10,000 test images.
3：List of Experimental Equipment and Materials:
A computer with NVIDIA GPU for accelerated computing, TensorFlow and Keras libraries, and the CIFAR-10 dataset.
4：Experimental Procedures and Operational Workflow:
The dataset was preprocessed by normalizing pixel values. The CNN model was trained for 50 epochs with a batch size of 32, using Adam optimizer and categorical cross-entropy loss.
5：Data Analysis Methods:
Accuracy and loss metrics were computed during training and validation. Confusion matrices and classification reports were generated for performance evaluation.
