2. Background and Concept

2.1 The Concept of Mixture-of-Experts (MoE)

The Mixture-of-Experts (MoE) approach is like having a team of specialists working together. Imagine you’re solving a complex puzzle, and instead of relying on a single person, you have a group of experts, each with unique skills. Each expert focuses on a specific part of the puzzle, and their combined efforts lead to a better solution.

In the context of neural networks, MoE divides the problem space into homogeneous regions, with each expert specializing in a subset of the input data. These experts work together to perform a task jointly. Rather than activating the entire neural network for every input, MoE selectively activates only the specific experts needed for a given task. This approach significantly improves efficiency and performance.

2.2 Evolution of Large Language Models (LLMs)

The journey of LLMs has been remarkable. Let’s explore its key milestones:

Statistical Language Models (SLMs) (1990s):

SLMs made predictions based on a few words before the current one (n-gram models).
Challenges: High-order models suffered from data sparsity due to estimating transition probabilities.
Overcame challenges using smoothing techniques.

2. Neural Language Models (NLMs):

They introduced neural networks(MLPs, RNNs) to capture word relationships.
Need help with deeper language understanding.
Improved word order prediction but lacked deeper meaning comprehension.

3. Transformer Models:
