🌸 SEA Model series Op.0: Saint Iberis d16 (Parameters: 376M)　日本語・英語バイリンガルモデル

このリポジトリはnanochatをより高速に学習・推論するために、LTCsおよびLFM2から着想を得たSLC2というモジュールを使用しています。 SEA Model series Op.0: Saint Iberisは元のnanoGPTと比較して学習時間を削減しながら、同等の性能を達成することが可能です。モデルは下記リポジトリからご自由に利用できます。

Ripository: Liquid_Time_nanochat_jp

🌸 SLC2 Formulation

y = B ⋅ ∏ᵢ₌ⱼ⁽ʲ⁺ᵏ⁾ Aᵢ ⋅ xᵢ

🌸 SLC2 pseudo code

python

----------------------------------------
Algorithm: SLC2
----------------------------------------
Input: x: (B, S, E)
Output: y: (B, S, E)
    1: alpha, A, B, x₁ <- Linear(x)
    2: x₂: (B, S, E) <- Convolution1D(E, E)(SiLU(alpha)*A*x₁)
    3: x₃: (B, S, E) <- B*SiLU(x₂)
    4: y: (B, S, E) <- Linear(x₃)
    5: return y
