Chapter 7 discusses Canonical Correlation Analysis, a different unsupervised learning problem than clustering. A new method called Weighted Multiple Kernel Canonical Correlation Analysis (WMKCCA) is proposed to leverage the importance of different data sources in the CCA objective . Beside the derivation of mathematical models, we present some preliminary results of using the mappings obtained by WMKCCA as the common information extracted from multiple data sources. Chapter 8 continues to discuss the gene prioritization problem started in Chapter 5.
Instead, α is solved via convex optimization. 3 Summary In this chapter we made a survey of several popular machine learning algorithms. The main finding was that these problems can all be simplified as the Generalized Rayleigh quotient form, given by minimize (W T PW )−1 (W T QW ) or maximize(W T PW )−1 (W T QW ). 1 we summarize the objectives, the mappings and the constraints corresponding of these algorithms in terms of Generalized Rayleigh quotient. 1 Summary of several machine algorithms and the mappings to the Generalized Rayleigh quotient form 36 2 Rayleigh Quotient-Type Problems in Machine Learning References 37 References 1.
