This research presents a comprehensive analysis of Indian patent assertions from 2016 to 2021, marked by significant technological and economic developments. The study uses advanced computational techniques to address the growing complexity and volume of patent data, which traditional analysis methods fail to manage effectively. The research aims to dissect the vast dataset of Indian patent claims, employing analytical methods including summary statistics, trend analysis, field comparison, correlation analysis, panel data analysis, and ANOVA to unveil nuanced insights into India’s innovation landscape dynamics. The findings reveal a discernible surge in patent filings, underscoring an evolving innovation ecosystem responsive to technological advancements and global trends. The trend analysis elucidates the shifts in technology focus, identifying sectors that exhibit rapid growth or decline in patent activities. Comparative analysis across different technology domains highlights India’s innovative strengths and areas needing attention, aligning with global innovation patterns. Correlation and panel data analyses offer a deeper understanding of the interplay between different sectors and temporal shifts in patent filings, unveiling the underlying factors driving these trends. The ANOVA results confirm the sector-specific dynamism in India’s patent landscape, indicating significant differences in claim numbers across fields. This study provides critical insights for policymakers, investors, and industry stakeholders, guiding strategic decision-making and policy formulation to foster a conducive environment for innovation. The robust methodological approach and comprehensive analysis underscore the study’s contribution to understanding and navigating the complexities of India’s IP ecosystem, offering a valuable resource for shaping future innovation strategies and enhanding India’s global innovation footprint.

Graphs such as social networks and molecular graphs are ubiquitous data structures in the real world. Due to their prevalence, it is of great research importance to extract meaningful patterns from graph structured data so that downstream tasks can be facilitated. Instead of designing hand-engineered features, graph representation learning has emerged to learn representations that can encode the abundant information about the graph. It has achieved tremendous success in various tasks such as node classification, link prediction, and graph classification and has attracted increasing attention in recent years. In this tutorial, we systematically review the foundations, techniques, applications and advances in graph representation learning. We first introduce the foundations on graph theory and graph Fourier analysis. We then cover the key achievements of graph representation learning in recent years. Concretely, we discuss the six topics: 1) network embedding theories and systems;2) foundations of graph neural networks (GNNs);3) CogDL toolkit for GNNs;4) scalable GNNs;5) self-supervised learning in GNNs and 6) heterogeneous graphs and heterogeneous GNNs. Finally, we will introduce the applications of graph representation learning with a focus on recommender systems.

The accuracy and explainability of data-driven now-casting models are of great importance in many socio-economic sectors reliant on weather-dependent decision making. This paper proposes a novel architecture called Small Attention Residual UNet (SAR-UNet) for precipitation and cloud cover nowcasting. Here, SmaAt-UNet is used as a core model and is further equipped with residual connections, parallel to the depthwise separable convolutions. The proposed SAR-UNet model is evaluated on two datasets, i.e., Dutch precipitation maps ranging from 2016 to 2019 and French cloud cover binary images from 2017 to 2018. The obtained results show that SAR-UNet outperforms other examined models in precipitation nowcasting from 30 to 180 minutes in the future as well as cloud cover nowcasting in the next 90 minutes. Furthermore, we provide additional insights on the nowcasts made by our proposed model using Grad-CAM, a visual explanation technique, which is employed on different levels of the encoder and decoder paths of the SAR-UNet model and produces heatmaps highlighting the critical regions in the input image as well as intermediate representations to the precipitation. The heatmaps generated by Grad-CAM reveal the interactions between the residual connections and the depthwise separable convolutions inside of the multiple depthwise separable blocks placed throughout the network architecture.
