Core Viewpoint - The article introduces a new method called "Goldfish Loss" that allows large language models to avoid memorizing training data verbatim, thereby enhancing their ability to learn language patterns while reducing the risk of overfitting [1][4]. Group 1: Goldfish Loss Concept - Goldfish Loss encourages models to forget specific details by randomly omitting a small portion of tokens during loss calculation [3][6]. - This method prevents the model from reproducing the training data word-for-word, while still enabling it to generate coherent text [4][9]. - The approach utilizes a hashing-based masking strategy to ensure consistency in the tokens that are omitted during training [8][14]. Group 2: Comparison with Traditional Methods - Unlike traditional regularization methods like Dropout, which introduce noise randomly, Goldfish Loss employs a static masking technique to consistently omit the same tokens across training iterations [11][19]. - This consistency fundamentally prevents the model from memorizing complete training sequences, as it cannot piece together omitted tokens from different training instances [12][14]. Group 3: Experimental Results - Experiments demonstrated that in extreme scenarios, standard training led to the model memorizing 84 out of 100 articles, while Goldfish Loss resulted in no memorization [22][24]. - In standard training scenarios, Goldfish Loss also significantly reduced the model's tendency to reproduce training data verbatim [24]. - Performance tests indicated no systematic differences in overall capabilities between models trained with Goldfish Loss and those trained with standard loss methods [26]. Group 4: Implications and Considerations - The core of Goldfish Loss lies in ignoring certain tokens during gradient calculations, which may require the model to process more data to compensate for the omitted information, potentially affecting computational efficiency [28].

Group 2: Framework Components - The CausalMACE framework consists of three main components: Judger, Planner, and Worker [7]. - Judger ("裁判") verifies the legality of actions in real-time and provides feedback on success or failure, ensuring all agents operate under the same game rules [11]. - Planner ("总工") breaks down complex tasks into smaller sub-tasks and creates a rough flowchart based on game rules, refining it through causal reasoning to ensure task dependencies remain valid [12][14]. - Worker ("调度室") utilizes depth-first search to split the causal graph into multiple production lines, calculating a "busy index" for real-time task reassignment among agents [16]. Group 3: Experimental Results - The experimental results indicate that CausalMACE significantly enhances both completion rates and efficiency in benchmark tasks such as construction, cooking, and escape rooms, achieving up to a 12% increase in task completion rates and a maximum efficiency improvement of 1.5 times compared to baseline methods [17]. - In the VillagerBench benchmark tasks, CausalMACE outperformed AgentVerse and VillagerAgent across various metrics, demonstrating its effectiveness in multi-agent collaboration [18]. Group 4: Author Information - The lead author of the paper is Professor Wang Hao, an assistant professor and doctoral supervisor at Hong Kong University of Science and Technology (Guangzhou), with a research background in generative AI models and 3D reconstruction [19][20].
