Each kernel is trained to detect a specific local pattern: early-layer kernels typically learn to detect low-level features like edges and color gradients, while kernels in deeper layers combine these into detectors for more complex, higher-level patterns (textures, object parts, and eventually whole-object representations as receptive fields grow with depth). A convolutional layer typically applies many kernels in parallel, each producing its own output channel, collectively forming the layer&#8217;s feature map.<br\/>The other options describe separate CNN components with distinct responsibilities: the loss function (B) is computed at the network&#8217;s output based on the difference between predictions and ground truth, entirely separate from the kernel&#8217;s role in feature extraction. Classification (C) is typically performed by fully connected (dense) layers &#8211; often with a softmax activation &#8211; placed after the convolutional feature- extraction stack, not by the kernels themselves. Normalization (D) is handled by dedicated layers such as batch normalization or layer normalization, inserted between convolutional layers to stabilize activations, again a separate mechanism from the convolution operation itself.<br\/>Reference: Core Machine Learning and AI Knowledge domain &#8211; CNN architecture, kernels\/filters, feature extraction.<\/div><input type='button' class='showchecked' style='margin: 10px 0;' onclick='showanswer1(6,this)' id='btn-6' value='See Answer'  \/><input type='hidden' id='questionType6' value='radio' class=''><\/div><div class='watu-question' id='question-7'><div class='question-content'><p><strong>QUESTION 28<\/strong><br \/>You are working with a large multimodal dataset that contains images and corresponding text descriptions.

L1\/L2 regularization penalizes large weights, preventing the model from becoming too complex. Data augmentation increases the Size and diversity of the training data, reducing overfitting. Dropout randomly deactivates neurons during training, preventing co-adaptation and improving generalization.

Oversampling the audio data ensures that the model sees more examples from the audio modality during training. Reducing the dimensionality of the image features can prevent them from dominating the fusion process.
