-- **Lightweight Model Architecture**: Uses a decoder-only Patch Transformer 
with RMSNorm, rotary positional embeddings, and SiLU-GLU feed-forward networks 
to balance forecasting capability and inference efficiency at a small parameter 
scale.
-- **Multi-Token Prediction**: Predicts multiple patches at each decoding step, 
reducing the number of autoregressive decoding steps required for long forecast 
horizons.
-- **Probabilistic Forecasting**: Outputs nine quantiles from 0.1 to 0.9. 
AINode uses the p50 median as the point forecast.
-- **Patch Decoding**: Groups the time series into fixed-size patches before 
the attention module to improve temporal feature extraction and decoding 
efficiency.
-- **Instance Normalization**: Standardizes each time series before model input 
and applies denormalization after output to mitigate distribution shifts across 
series.
-- **Input Scope**: Focuses on univariate forecasting and does not support 
multivariate targets or covariates.

前馈网络,在较小参数规模下兼顾预测能力和推理效率。
-- **多 Token 预测**:每个解码步骤可同时预测多个 Patch,减少长预测范围下所需的自回归解码次数。
-- **概率性预测能力**:模型输出 0.1~0.9 共 9 个分位数,AINode 使用 p50 中位数作为点预测结果。
-- **Patch 解码**:在进入注意力模块前,将时间序列按照固定大小的 Patch 进行分组,以提高时序特征提取和解码效率。
-- **实例归一化**:在模型输入前对每条时间序列进行标准化,并在输出后执行反归一化,以缓解不同序列间的分布漂移。
-- **输入范围**:模型聚焦于单变量预测,不支持多变量目标及协变量输入。
