Before Michelangelo, we faced a number of challenges with building and deploying machine learning models at Uber related to the size and scale of our operations. While data scientists were using a wide variety of tools to create predictive models (R,scikit-learn, custom algorithms, etc.), separ...

Full size image Discussion This paper proposed two automatic methods to measure the NSA based on CT data: the 2D measurement by projecting the 3D model to the 2D projection plane and direct 3D measurement. First, we used PointNet++ neural network to achieve high-precision segmentation of the fe...
Full size table Overfitting analysis Overfitting is a phenomenon that occurs due to a complex model and a simple database or a simple model and a complex database. The ratio of test to train RMSE shows an overfitting of a computational model. In the present research, models PPV1 to PPV11...
The objective of this paper is to present the state of the art of different drive train qualification and parameter sets on the topic of Unmanned Aerial Vehicles (UAVs). Focus is set on a Quadrocopter UAV model; the involved electrical and mechanical systems are analysed. Principal components of...
These model data sets were used to train a data-driven model for preceding the SAGD performance, while the remaining evaluation data set is not used in the training process and will be employed to evaluate the model after training as new data. This 135 evaluation points data set also follows...
Full size image 2.2.2Experimental Design and Procedures We constructed a D-efficient fractional-factorial design with three blocks of ten choice sets using the Ngene software version 1.2.0. Each choice set consists of two alternatives plus a status-quo option, with the current state of air-pollu...
The plasticity of the immune system involves selection rather than instruction as, by extremely rapid mutation and recombination, the immune system finds a match for the foreign antigen and this then sets in train rapid synthesis of the antibody from the mutated gene that provided the match. The...
Full size image The inlet was designated with fixed freestream reduced velocity and the outlet was set with zero gradient. The upper and lower walls were set as free stream boundary with no slip boundary condition of distance 10D from the edge of the square cylinder. According to the computati...
