gradient descent will take “steps” in the “downhill direction” towards the negative gradient. The size of the “step” taken is dependent on our learning rate. Choosing
As stated earlier, during the training of the Snapshot ensemble model, an aggressive learning rate scheduler has been used that allows the model to reach a new local minimum each time when there is a drop in the learning rate. When it tries to reach a local minimum, it extracts variegated...
2019).Fig. 2.a shows a schematic diagram of a basic CNN model. A CNN model uses grid-patterned data, such as images, as inputs and learns features from low to high levels based on trained weights (LeCun et al., 1998). Regardless of the specific task, using deep learning and the ...
the architectures of the machine learning models themselves have become increasingly more complex. Most of the time, these model architectures are as specific to a given task as feature engineering used to be.

Additionally, the introduction of contrastive learning aims to improve the model's classification ability. Through cross-validation and independent dataset testing experiments, DAC-AIPs achieves superior performance compared to existing state-of-the-art models. In cross-validation, the classification ...
