Architecture Brief Overview

The Mobillama, baseline Small Language Model (SLM) architecture of 0.5 cardinal (0.5B) parameters, is inspired by TinyLlama and Llama-2 models. This baseline has N layers pinch hidden dimensions of M and intermediate size (MLPs) of 5632. The vocabulary size is 32,000, and the maximum discourse magnitude is denoted arsenic C.

1. Baseline1: This has 22 layers pinch a hidden size of 1024.
1. Baseline2: This has 8 layers pinch a hidden size of 2048.

Both of the baselines faced challenges successful balancing accuracy and efficiency. Baseline1, pinch a smaller hidden size, enhances computational ratio but whitethorn discuss the model’s expertise to seizure analyzable patterns. Baseline2, pinch less layers, hampers the model’s extent and its capacity for heavy linguistic understanding.

To reside these issues, combining the advantages of some baselines into a azygous exemplary (22 layers and hidden size of 2048) results successful a larger 1.2 cardinal (1.2B) parameterized exemplary called “largebase,” pinch accrued training costs.

The authors past present their projected MobiLlama 0.5B exemplary design, aiming to support hidden magnitude size and the full number of layers while ensuring comparable training efficiency. This caller creation seeks to execute a equilibrium betwixt computational ratio and the model’s capacity to understand analyzable connection patterns.
