This paper proposes an efficient robot assembly skill learning framework based on only a few demonstrations. The process consists of two phases, e.g., the pre-training phase and self-learning phase. In phase, networks are initialized from demonstration data. A novel data augmentation model state transition is designed, which requires several human demonstrations to learn parameters reduces cost collection in pre-training. pre-trained further optimized by hybrid exploration strategy...

Early life stress correlates with a higher prevalence of neurological disorders, including autism, attention-deficit/hyperactivity disorder, schizophrenia, depression, and Parkinson's disease. These conditions, primarily involving abnormal development damage the dopaminergic system, pose significant public health challenges. Microglia, as primary immune cells in brain, are crucial regulating neuronal circuit survival. From embryonic stage to adulthood, microglia exhibit stage-specific gene...

Recently, Graph Convolutional Neural Network (GCN) is widely used in text classification tasks. And it has been effectively to accomplish tasks that are thought have a rich relational structure. However, due the sparse adjacency matrix constructed by GCN, GCN cannot make full use of context-dependent information classification, and not good at capturing local information. The Bidirectional Encoder Representation from Transformers (BERT) ability capture contextual sentences or documents, but...

Text classification is a fundamental task in natural language processing. This widely concerned and applied. However, previous methods mainly use traditional static word embedding, but embedding could not deal with the problem of polysemy. For this reason, we propose to utilize contextualized BERT effectively encode input sequence then temporal convolutional module which simply computes 1-D convolution extract high-level features, finally, max-pooling layer retains most critical features for...
