Abstract: The application provides a method for generative heterogeneous logic optimization based on critical path partitioning. The method includes: converting a digital logic circuit into an And-Inverter Graph (AIG) format; partitioning the AIG using reinforcement learning based on critical path information of the circuit to obtain critical-path-aware partitions so as to reduce influence of critical path changes brought by the partitioning on timing performance; respectively and automatically exploring an optimized structure and synthesis flow suitable for each partition using the reinforcement learning method; selecting optimization operators for various structures using a reinforcement learning agent guided by area-delay metrics and optimizing each partition; and merging the optimized partitions in the AIG format. In the application, the digital logic circuit is partitioned based on critical paths, and reinforcement learning is used to explore and optimize structures and strategies based on area and delay.

Abstract: A method for analyzing the seismic vulnerability of an urban building group based on Poisson binomial distribution includes these steps: (1) establishing a simplified numerical model of the building group; (2) selecting seismic motion records consistent with site features; (3) acquiring a structural and non-structural damage database for the building group; (4) creating a probability machine learning damage prediction model; (5) determining the unsafe probability of the building group; and (6) deducing a regional vulnerability model for the building group. Using simplified MDOF models based on building attribute parameters, numerical models accounting for variability between buildings are efficiently constructed. The probability machine learning model quantifies the intrinsic randomness of building responses and provides probability distribution parameters needed for the parameterized vulnerability model.

Abstract: Disclosed is a privacy-preserved method for constructing an aggregate thermal dynamic model of buildings, including the steps of: establishing a thermal dynamic model of one building region, and establishing an aggregate thermal dynamic model of buildings based on an aggregation equation; performing parameter estimation using a least square method based on a measurement equation, introducing a regular term to solve a sparsity problem, and obtaining a parameter estimation model in a compact form for the aggregate thermal dynamic model of buildings; and establishing a privacy-preserved parameter estimation method for the aggregate thermal dynamic model of buildings. Based on the technique, the aggregate modeling is performed on numerous buildings by a building load aggregator to participate in the operation and control of an energy system while preserving privacy of building users, promoting the mining of thermal inertia of buildings and enhancing the flexibility of operation and regulation of a power system.

Abstract: The invention discloses a ground motion intensity measure optimization method for seismic response prediction. The method includes the following steps: (1) building a building damage database; (2) optimizing ground motion intensity measures; (3) constructing a machine learning model; and (4) predicting damage states. According to the method, a combination of optimal ground motion intensity measures is selected by an elastic-net algorithm, wherein the efficiency and practicability in a current selection criterion are updated based on the goodness of fit and regression coefficient of the elastic-net model, thereby avoiding an assumption that intensity measures and structure response need to obey a logarithmic linear relationship and the limitation of intensity measure dimensions in traditional methods. By using the combination of optimal ground motion intensity measures as input variables, the prediction accuracy can be remarkably improved, and meanwhile the number of samples required is reduced.
