Ubiquitous Learning Log (ULL) is defined as a digital record of what you have learned in the daily life using ubiquitous technologies. This paper focuses on how to capture learning experiences in our daily life for vocabulary learning. In our previous works, we developed a system named SCROLL (System for Capturing and Reminding Of Learning Log) in order to log, organize, recall and evaluate the...

Artificial intelligence algorithms using passive and active learning versions of direct utility estimation, adaptive dynamic programming and temporal difference approaches to simulate an agent. The explored worlds consisted of discrete states (positions) bounded by internally generated “walls” that included one or more terminal states and a pre determined configuration of rewards for each state...

Laboratory studies of human category learning tend to emphasize passive learning by limiting participants’ control over the information they experience on every trial. In contrast, we explore the impact that active data selection has on category learning. In our experiment, participants attempted to learn categories under either entirely passive conditions, or by actively selecting and querying...

In this study, we examined the orientation dependency of spatial representations following various learning conditions. We assessed the spatial representations of human participants after they had learned a complex spatial layout via map learning, via navigating within a real environment, or via navigating through a virtual simulation of that environment. Performances were compared between cond...

The Internet gives incredible opportunities for companies to learn about their consumers. Most managers view learning as actively asking questions directly to consumers and listening to their responses. Alternatively, managers can passively learn by observing the choices that consumers make. Passive learning techniques include user profiling, collaborative filtering, path analysis, and conjoint...

Background & Aims: Diabetes mellitus is a chronic metabolic disorder that in the long-term is accompanied with deficits in learning, memory, and cognitive skills. Due to the existing evidence regarding the anti-diabetic potential of acetyl-L-carnitine (ALC), the effect of its long-term administration on learning and spatial memory deficits was investigated in diabetic rats. Methods: In this exp...

This paper studies graphical model selection, i.e., the problem of estimating a graph of statistical relationships among a collection of random variables. Conventional graphical model selection algorithms are passive, i.e., they require all the measurements to have been collected before processing begins. We propose an active learning algorithm that uses junction tree representations to adapt f...

We investigate the label complexity of active learning under some smoothness assumptions on the data-generating process. We propose a procedure, PLAL, for “activising” passive, sample-based learners. The procedure takes an unlabeled sample, queries the labels of some of its members, and outputs a full labeling of that sample. Assuming the data satisfies “Probabilistic Lipschitzness”, a notion o...
