In this work we investigate function approximation using Hierarchical Networks. We start of by investigating the theory proposed by Poggio et al [2] that Deep Learning Convolutional Neural Networks (DCN) can be equivalent to hierarchical kernel machines with the Radial Basis Functions (RBF).We investigate the difficulty of training RBF networks with stochastic gradient descent (SGD) and hierarchical RBF. We discovered that training singled layered RBF networks can be quite simple with a good initialization and good choice of standard deviation for the Gaussian. Training hierarchical RBFs remains as an open question, however, we clearly identified the issue surrounding training hierarchical RBFs and potential methods to resolve this. We also compare standard DCN networks to hierarchical Radial Basis Functions in tasks that has not been explored yet; the role of depth in learning compositional functions.

Full textAtt snabbt kunna approximera en funktion baserat på ett fåtal data-punkter är ett viktigt problem, speciellt inom områden där tillgängliga datamängder är relativt små, till exempel inom delar av robotikområdet. Under de senaste åren har flexibla och skalbara inlärningsmetoder, såsom exempelvis neurala nätverk, uppvisat framstående egenskaper i scenarion där en stor mängd data finns att tillgå. Dessa metoder tenderar dock att prestera betydligt sämre i låg-data regimer vilket motiverar sökandet efter alternativa metoder. Ett sätt att adressera denna begränsning är genom att utnyttja tidigare erfarenheter och antaganden (eng. prior information) om funktionsklassen som skall approximeras när sådan information finns tillgänglig. Ibland kan denna typ av information uttryckas i sluten matematisk form, men mer generellt är så inte fallet. Denna uppsats är fokuserad på det mer generella fallet där vi endast antar att vi kan sampla datapunkter från en databas av tidigare erfarenheter - exempelvis från en simulator där vi inte känner till de interna detaljerna. För detta ändamål föreslår vi en metod för att lära från dessa tidigare erfarenheter genom att i förväg träna på en större datamängd som utgör en familj av relaterade funktioner. I detta steg bygger vi upp ett så kallat latent funktionsrum (eng. latent task embeddings) som innesluter alla variationer av funktioner från träningsdatan och som sedan effektivt kan genomsökas i syfte av att hitta en specifik funktion - en process som vi kallar för finjustering (eng. fine-tuning). Den föreslagna metoden kan betraktas som ett specialfall av en auto-encoder och använder sig av samma ide som den nyligen publicerade Conditional Neural Processes metoden där individuella datapunkter enskilt kodas och grupperas. Vi utökar denna metod genom att inkorporera en sidofunktion (eng. auxiliary function) och genom att föreslå ytterligare metoder för att genomsöka det latenta funktionsrummet efter den initiala träningen. Den föreslagna metoden möjliggör att sökandet efter en specifik funktion typiskt kan göras med endast ett fåtal datapunkter. Vi utvärderar metoden genom att studera kurvanpassningsförmågan på sinuskurvor och genom att applicera den på två robotikproblem med syfte att snabbt kunna identifiera och styra dessa dynamiska system.
