迹运算的部分请参考Deep Learning Book的2.10小节。可见,PCA的这两个目的最终达到的效果是一样的。 求解 现在有了公式就好办了,我们先用拉格朗日乘子法将有约束的优化问题转化成无约束的优化问题: \boldsymbol{w} = \underset{\boldsymbol{w}}{\mathrm{argmax}} \, L(\boldsymbol{w},\lambda) = \underset...
Ask a smart home device for the weather forecast, and it takes several seconds for the device to respond. One reason this latency occurs is because connected devices don't have enough memory or power to store and run the enormous machine-learning models needed for the device to understand wha...

Deep learningClass balancingRGB-D3DFacilitiesBuilding information modeling (BIM) has a semantic scope that encompasses all building systems, e.g. architectural, structural, mechanical, electrical, and plumbing. Automated, comprehensive digital modeling of buildings will require methods for semantic ...
The method comprises encoding, by an encoder, a real image of an object to produce a first compressed image as a first vector in a latent space, wherein the real image is free of defects. A decoder then generates a reconstructed image from the first vector in the latent space, wherein ...
Principles of learning and knowledge representation are studied in complex neural networks with a large number of parameters. Our neural networks incorporate both deep and shallow knowledge representations. In the case of a stationary environment, the neural nets can develop a deep understanding of the...
Once the agent has all the relevant words, yet they have to be uttered in a way that they have some meaning. So, after the generation of words, the formation of meaningful sentences takes places and finally, the agent speaks them out to the user. ...
The perceptual recognition of objects is conceptualized to be a process in which the image of the input is segmented at regions of deep concavity into an arrangement of simple geometric components. The fundamental assumption of the proposed theory, recognition-by-components (RBC), is that a ...
At the heart of this process is a comprehensive competency or capability model based on the organization’s strategic direction. For example, a key competency for a segment of an e-commerce company’s workforce could be “deep expertise in big data and predictive analytics....
