This paper presents a novel model protection paradigm Model Locking that locks the performance of a finetuned model on private data to make it unusable or unextractable without the right key. Specifically, we proposed a diffusion-based framework dubbed ModelLock that explores text-guided image editing to transform the private finetuning data into unique styles or blend new objects into the background. A model finetuned on this edited dataset will be locked and can only be unlocked by the key prompt, i.e., the same text prompt used to edit the data. We conduct extensive experiments on both image classification and segmentation tasks and show that 1) ModelLock can effectively lock finetuned models without significantly reducing their unlocked performance, and more importantly, 2) the locked model cannot be easily unlocked without knowing both the key prompt and the diffusion model. Our work opens up a new direction for intellectual property protection of private models. © 2024 ACM.

sEMG (surface electromyography) signal control of bionic prostheses has been widely studied over the past few years. In particular, sparse sEMG signals are rapidly developing in the field of gesture recognition for their convenience, noninvasiveness, and ease of access. However, compared with high-density EMG signals, sparse EMG signals lack rich feature information, which in turn affects gesture recognition accuracy. In order to reduce the loss of feature information of sparse EMG signals in the spatio-temporal dimension, this paper proposes a hybrid neural network Res-LSTM combining residual network and long short-term memory network. The ordinary convolutional blocks in the CNN network are replaced with residual blocks, and the final fully connected layer is removed and a constant mapping layer is added to adequate extraction of spatial feature information of the data. The Res layer’s output is utilized as the input for the long and short-term memory (LSTM) network, which further extracts the features of the data in the temporal dimension, and finally completes the categorization output through a fully connected layer. The average accuracy of 91.11% for gesture-motion classification was verified by training on a homebrew dataset;and tested on a public dataset, NinaPro DB1, with an average accuracy of 91.03%. The experimental findings indicate that the proposed Res-LSTM network framework contributes to solving the problem of lack of feature information of sparse sEMG signals and improves the pattern recognition accuracy. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

Predicting Drug-drug interaction (DDI) is essential for drug combination therapy to reduce unexpected adverse drug reactions. However, existing methods cannot adequately consider multimodal features or molecular graph structural information, and it is a challenge to extract and fuse multimodal features effectively. In this study, we propose a multimodal feature fusion-based node representation learning for Drug-Drug interaction prediction, termed MFF-NRL. We used a graph convolutional network to extract the features of molecular graphs in terms of a node feature update strategy. Then, we take the molecular graph embeddings as a feature matrix, construct an adjacency matrix based on the DDI network, and propose a representation learning method based on a multi-head self-attention mechanism. Finally, a multimodal feature fusion module is presented to effectively integrate the molecular graph and DDI network embedding information, and the multi-layer perceptron (MLP) layer is further applied for DDI prediction. The MFF-NRL algorithm's effectiveness has been verified by four representative evaluation metrics on the ZhangDDI dataset. The experimental results demonstrate that MFF-NRL performs better than state-of-the-art approaches.
