Image classification involves categorizing an entire image into a single label, while object detection identifies and locates multiple objects within an image, providing bounding boxes around them. Understanding this distinction is crucial for applying the right techniques in computer vision tasks.
How to Answer ItStructure your answer by first defining both terms clearly, then providing examples of use cases for each. Mention relevant algorithms or frameworks that are commonly used for these tasks.
CNNs are a class of deep learning models designed for processing structured grid data, such as images. They use convolutional layers to automatically learn spatial hierarchies of features, pooling layers to reduce dimensionality, and fully connected layers for classification. This architecture allows CNNs to excel in image-related tasks.
How to Answer ItUse the STAR method to explain your understanding of CNNs, focusing on their architecture and how they process images. Highlight any practical experience you have with implementing CNNs.
I primarily use Python with libraries such as OpenCV for image processing, TensorFlow and Keras for building deep learning models, and Matplotlib for visualization. These tools provide a robust framework for developing and deploying computer vision applications.
How to Answer ItMention specific tools and libraries you are proficient in, along with examples of how you have used them in past projects. Highlight your technical proficiency and familiarity with the software.
In a recent project, I developed an object detection system for real-time video analysis. The challenge was to optimize the model for speed without sacrificing accuracy. I implemented techniques like model pruning and quantization, which improved performance significantly.
How to Answer ItUse the STAR method to describe the situation, the specific challenge, the actions you took, and the results achieved. Focus on your problem-solving skills and technical expertise.
To combat overfitting, I employ techniques such as data augmentation, dropout layers, and early stopping during training. These methods help ensure that the model generalizes well to unseen data, improving its performance in real-world applications.
