Summary: In this paper, we tackle with the problem of analyzing datasets with
different resolution such as a pair of user's individual data and user group's
data, for example "userA visited shopA 5 times" and "users whose attributes are
men purchased itemA 80 times in total". In order to establish a basic approach
to this problem, we focus on the simplified scenario and propose a new
probabilistic model called probabilistic non-negative inconsistent-resolution
matrices factorization (pNimf). pNimf is rigorously derived from the data
generative process using latent high-resolution data which underlie
low-resolution data. We conduct experiments on real purchase log data and
confirm that the proposed model provides superior performance, and that the
performance improves as the number of low-resolution data increases. These
results imply that our way of modeling using latent high-resolution data can
become the basic approach to the problem of analyzing dataset with different
resolution.

Summary: Improvements in information technology have made it easier for industry to
communicate with their customers, raising hopes for a scheme that can estimate
when customers will want to make purchases. Although a number of models have
been developed to estimate the time-varying purchase probability, they are
based on very restrictive assumptions such as preceding purchase-event
dependence and discrete-time effect of covariates. Our preliminary analysis of
real-world data finds that these assumptions are invalid: self-exciting
behavior, as well as marketing stimulus and preceding purchase dependence,
should be examined as possible factors influencing purchase probability. In
this paper, by employing the novel idea of hierarchical time rescaling, we
propose a tractable but highly flexible model that can meld various types of
intrinsic history dependency and marketing stimuli in a continuous-time
setting. By employing the proposed model, which incorporates the three factors,
we analyze actual data, and show that our model has the ability to precisely
track the temporal dynamics of purchase probability at the level of
individuals. It enables us to take effective marketing actions such as
advertising and recommendations on timely and individual bases, leading to the
construction of a profitable relationship with each customer.

Summary: A majority of home electric appliances are now remotely operable with remote
controllers. Users therefore need to operate a wide variety of remote
controllers with designs that vary by model and by manufacturer. Also, along
with the sophistication and functionality of the appliances, these remote
controllers are each provided with an increased number of operation buttons.
This makes it more difficult for users to find the correct button from the many
buttons. Further, a television set, for example, is commonly used combined with
other appliances. Users are then required to manipulate remote controllers for
several appliances in the correct order, while thinking about the necessary
procedure.

Summary: A novel probabilistic framework is proposed for analyzing cross-modal
nonverbal interactions in multiparty face-to-face conversations. The goal is to
determine "who responds to whom, when, and how" from multimodal cues including
gaze, head gestures, and utterances. We formulate this problem as the
probabilistic inference of the causal relationship among participants'
behaviors involving head gestures and utterances. To solve this problem, this
paper proposes a hierarchical probabilistic model; the structures of
interactions are probabilistically determined from high-level conversation
regimes (such as monologue or dialogue) and gaze directions. Based on the
model, the interaction structures, gaze, and conversation regimes, are
simultaneously inferred from observed head motion and utterances, using a
Markov chain Monte Carlo method. The head gestures, including nodding, shaking
and tilt, are recognized with a novel Wavelet-based technique from magnetic
sensor signals. The utterances are detected using data captured by lapel
microphones. Experiments on four-person conversations confirm the effectiveness
of the framework in discovering interactions such as question-and-answer and
addressing behavior followed by back-channel responses.

Summary: Our new research project called "ambient intelligence" concentrates on the
creation of new lifestyles through research on communication science and
intelligence integration. It is premised on the creation of such virtual
communication partners as fairies and goblins that can be constantly at our
side. We call these virtual communication partners mushrooms.
To show the essence of ambient intelligence, we developed two multimodal
prototype systems: mushrooms that watch, listen, and answer questions and a
Quizmaster Mushroom. These two systems work in real time using speech, sound,
dialogue, and vision technologies.
We performed preliminary experiments with the Quizmaster Mushroom. The
results showed that the system can transmit knowledge to users while they are
playing the quizzes.
Furthermore, through the two mushrooms, we found policies for design effects
in multimodal interface and integration.

Summary: A display device called intuition-driven monitor will be introduced. The
device has been developed by combining a LCD, a flexible arm suspending the
display, angle sensors and a CCD camera, and is directly manipulated by a user
with his direct operations by hands, eye-gaze and facial expressions. A user is
able to explore virtual space and manipulate virtual environment with gestures
and the sense of haptics.
