What were the differences between the baseline, small, and bigger models in terms of architecture and performance?
The differences between the baseline, small, and bigger models in terms of architecture and performance can be attributed to variations in the number of layers, units, and parameters used in each model. In general, the architecture of a neural network model refers to the organization and arrangement of its layers, while performance refers to how well the model can learn and make accurate predictions.
Starting with the baseline model, it is typically the simplest and most straightforward architecture. It usually consists of a single layer with a few units, also known as neurons or nodes. This model is often used as a starting point to establish a baseline performance for more complex models. Due to its simplicity, the baseline model may struggle to capture intricate patterns in the data and may exhibit underfitting, where the model fails to capture the underlying relationships in the data.
Moving on to the small model, it typically includes multiple layers with a moderate number of units. By increasing the number of layers and units, the small model becomes more capable of capturing complex patterns in the data. This increased capacity allows the model to learn more intricate representations and potentially improve its performance compared to the baseline model. However, there is a trade-off between model complexity and the risk of overfitting. Overfitting occurs when the model becomes too specialized in the training data and fails to generalize well to unseen data.
Finally, the bigger model is characterized by a larger number of layers and units, resulting in a significantly more complex architecture. With a higher capacity for learning, the bigger model has the potential to capture even more intricate patterns in the data. However, this increased complexity also increases the risk of overfitting. To mitigate overfitting, techniques such as regularization or dropout can be applied during the training process.
In terms of performance, the baseline model is likely to have the lowest accuracy due to its simplicity and limited capacity to capture complex patterns. The small model, with its increased capacity, may exhibit improved performance compared to the baseline model. However, if the small model becomes too complex, it may suffer from overfitting and perform poorly on unseen data. The bigger model, with its even higher capacity, has the potential to achieve better performance than the small model if properly regularized to prevent overfitting.
To summarize, the baseline, small, and bigger models differ in terms of their architecture and performance. The baseline model is the simplest with a single layer, while the small and bigger models have multiple layers and more units. The small model strikes a balance between complexity and performance, while the bigger model has a higher capacity for learning but requires careful regularization to avoid overfitting.
