What are the sequential learning types to optimize the solution?

Question

The question asks about the sequential learning types used to optimize the solution. Here are the options considered: 
Option 1: Gradient Descent. This is a fundamental optimization method where the parameters are updated iteratively in the direction that reduces the loss function the most. It treats the entire dataset at once (batch) in its vanilla form, and in broader contexts serves as the baseline family of optimization techniques for learning models. Its role in sequential or iterative improvement is as the general approach from which variants are derived.
Option 2: Stochastic Gradient Descent. This is a variant of gradient descent designed for efficiency on large datasets. Instead of computing the gradient over the full dataset, it updates parameters using individual (or small batch) samples, producing more frequent updates and often faster convergence in practice for large-scale problems. It embodies the sequential/iterative nature of updating parameters as data points flow in, which aligns with the idea of sequential learning to optimize solutions over time.
Now, evaluating the choices helps clarify their relation to sequential optimization: 
- Gradient Descent (Option 1) embodies the core idea of iterative improvement, but depending on implementation it can be batch-based. When used in a sequential or iterative context, it aligns with the general principle of gradually adjusting parameters to minimize loss.
- Stochastic Gradient Descent (Option 2) explicitly captures the sequential, incremental update process, as each (or mini-batch) example contributes to a new update step and thus is a quintessential sequential optimization approach for large datasets.
If the aim is to identify learning types that optimize solutions through sequential updates, both options describe important, widely used methods in the optimization toolbox. The distinction lies in how data is processed at each update and how frequently updates occur, with SGD emphasizing frequent, smaller updates and Gradient Descent often representing a full-batch, one-shot or less frequent update depending on the variant used.
In summary, why these options fit into the concept: Gradient Descent provides the foundational update rule for reducing loss, while Stochastic Gradient Descent extends that rule to a sequential data-processing regime, enabling quicker iterations on large-scale data. Both are connected to the idea of sequential improvement in learning systems.
