Let's dive into a few of the key algorithms.
BootstrapFewShotWithRandomSearch takes the BootstrapFewShot approach to the next level. It runs several instances of BootstrapFewShot with different random combinations of demos and evaluates the performance of each. The key here is the extra parameter called "num_candidate_programs," which defines how many random programs will be tested. This random search helps to identify the best combination of inputs for optimizing AI performance.
BootstrapFewShotWithOptuna builds upon the BootstrapFewShot method but adds a layer of sophistication by incorporating Optuna, a powerful optimization tool. This algorithm tests different demo sets using Optuna's trials to maximize performance metrics. It’s designed to automatically choose the best sets of demos, helping to fine-tune the learning process.
KNNFewShot uses a familiar technique: the k-Nearest Neighbors (KNN) algorithm. In this context, it finds the closest matching examples from a given set of training data based on a new input. These similar examples are then used for BootstrapFewShot optimization, helping the AI agent to learn more effectively by focusing on relevant data.
COPRO is a method that refines instructions for each step of a process, continuously improving them through an optimization process called coordinate ascent, which is similar to hill climbing. It adjusts instructions iteratively based on a metric function and the existing training data. The "depth" parameter in COPRO controls how many rounds of improvement the system will undergo to reach the optimal set of instructions.
Lastly, MIPRO and MIPROv2 are particularly smart methods for generating both instructions and examples during the learning process. They use Bayesian Optimization to efficiently explore potential instructions and examples across different parts of the program. MIPROv2, an upgraded version, is faster and more cost-effective than its predecessor, delivering more efficient execution.
These algorithms aim to improve how AI systems learn, particularly when dealing with fewer examples or more complex tasks. They are geared toward helping AI agents perform better in environments where data is sparse, or the learning task is particularly challenging.
