Contrastive Learning Penalty (CLP)

CLP is a novel loss function designed to address the limitations of existing contrastive learning methods for improved performance in information retrieval tasks. It incorporates a penalty term that encourages the model to learn more discriminative representations by considering the similarity between negative samples and their corresponding queries.

The CLP loss function is defined as follows:

where:

h_i: The embedding of the query for the i-th instance.
h_i⁺: The embedding of the positive sample for the i-th instance.
H^': The set of negative samples for the i-th instance.
h^': The embedding of the negative sample's query.
H^*: the set of positive queries for the documents corresponding to the negative samples
sim(a, b): The cosine similarity function between embeddings a and b.
τ: The temperature parameter.
λ: The balancing parameter between the contrastive loss and the penalty term.

The difference between Contrastive Learning Loss and Contrastive Learning Penalty Loss:

Model

Model Name	Introduction
bge-m3-ko-CLPL-interMoE	This model applies CLPL and MoE, trained on the MIRACL Korean training dataset. MoE is applied to the intermediate layer, and only the MoE layers were trained during fine-tuning.
bge-m3-fa-CLPL-interMoE	This model applies CLPL and MoE, trained on the MIRACL Persian training dataset. MoE is applied to the intermediate layer, and only the MoE layers were trained during fine-tuning.
bge-m3-hi-CLPL-interMoE	This model applies CLPL and MoE, trained on the MIRACL Hindi training dataset. MoE is applied to the intermediate layer, and only the MoE layers were trained during fine-tuning.

Data

Performing negative sampling using the ANCE methodology and generating negative sample's positive queries through the Gemini 1.5 Pro model, which are required for CLPL.
