Fields§

§wq: WeightMatrix§bq: Option<Vec<f32>>§wk: WeightMatrix§bk: Option<Vec<f32>>§wv: WeightMatrix§bv: Option<Vec<f32>>§wo: WeightMatrix§bo: Option<Vec<f32>>§qk_norm: Option<QkLayerNorm>

A LayerNorm over the WHOLE Q / K projection, with biases, when the file carries one (bert.cpp:109-123; jina-bert-v2.cpp: 30-35 creates the pair optional). Not per head: the reshape at :110 is n_embd_head * n_head wide, so one norm covers every head’s channels together.

§pre_attn_norm: Option<Vec<f32>>

attn_norm / ffn_norm: the PRE-norm weights, Some exactly for BertTopology::PreNormRms.

§pre_ffn_norm: Option<Vec<f32>>§attn_out_norm_w: Option<Vec<f32>>

attn_output_norm, applied after the attention residual. Some exactly for BertTopology::PostNormLayerNorm.

§attn_out_norm_b: Option<Vec<f32>>§attn_norm_2: Option<(Vec<f32>, Vec<f32>)>

attn_norm_2, jina-bert-v2’s second attention norm (bert.cpp:156-159): the LAYER INPUT is re-added and normed a second time before the FFN reads it.

§ffn_up: WeightMatrix§ffn_up_b: Option<Vec<f32>>§ffn_gate: Option<WeightMatrix>

ffn_gate, present exactly for BertFfn::SwigluPar.

§ffn_down: WeightMatrix§ffn_down_b: Option<Vec<f32>>§layer_out_norm_w: Option<Vec<f32>>

layer_output_norm, applied after the FFN residual. Some exactly for BertTopology::PostNormLayerNorm.

§layer_out_norm_b: Option<Vec<f32>>
