Linking unlearning with innovation through organizational memory and technology
While the information technologies provide organizational members with explicit concepts, such as
writing instruction manuals, the ‘organizational memory’ provides individuals with tacit knowledge, such as systematic sets, routines and shared visions. This means that individuals within an organization learn by using both the organizational memory and the information technologies. They interact to reduce organizational information needs contributing to improve organizational innovativeness. However, the utilization of the organization memory or the technology infrastructure does not guarantee that appropriate information is used in appropriate circumstances or that information is appropriately updated. In other words, previous memories reflect a world that is only partially understood and assimilated, which might lead individuals to doing the wrong things right or the right things wrong. This paper examines the relative importance and significance of the existence of unlearning to the presence and nature of ‘organizational memory and technology’. We further examine the effect of the existence of organizational memory and information technology on conditions that promote organizational innovativeness. These relationships are examined through an empirical investigation of 291 large Spanish companies. Our analysis found that if the organization considers the establishment of an unlearning culture as a prior step in the utilization of organization memory or the technology infrastructure through organizational innovativeness, then organization memory and technology have a positive influence on the conditions that stimulate organizational innovativeness
Analyzing an absorptive capacity : unlearning context and information system capabilities as catalysts for innovativeness
This study examines the impact of a company’s unlearning context and information
system (IS) capabilities on the company’s ability to challenge of basic beliefs and to
implement processes that are explicitly or tacitly helpful in the reception of new ideas
(absorptive capacity). We also examine the relationship between absorptive capacity
and the existence and enhancement of innovativeness. These relationships are examined through an empirical investigation of 286 large Spanish companies. Our results show that absorptive capacity is an important dynamic determinant for developing a company’s innovativeness. Moreover, this relationship is best explained with two
related constructs. Firstly, the company’s unlearning context plays a key role in
managing the tension between potential absorptive capacity and realised absorptive
capacity. Secondly, the results also shed light on a tangible means for managers to
enhance their company’s innovativeness through IS capabilities

Deep Neural Networks for the Recognition and Classification of Heart Murmurs Using Neuromorphic Auditory Sensors
Auscultation is one of the most used techniques for
detecting cardiovascular diseases, which is one of the main causes
of death in the world. Heart murmurs are the most common abnormal
finding when a patient visits the physician for auscultation.
These heart sounds can either be innocent, which are harmless, or
abnormal, which may be a sign of a more serious heart condition.
However, the accuracy rate of primary care physicians and expert
cardiologists when auscultating is not good enough to avoid most
of both type-I (healthy patients are sent for echocardiogram) and
type-II (pathological patients are sent home without medication or
treatment) errors made. In this paper, the authors present a novel
convolutional neural network based tool for classifying between
healthy people and pathological patients using a neuromorphic
auditory sensor for FPGA that is able to decompose the audio into
frequency bands in real time. For this purpose, different networks
have been trained with the heart murmur information contained in
heart sound recordings obtained from nine different heart sound
databases sourced from multiple research groups. These samples
are segmented and preprocessed using the neuromorphic auditory
sensor to decompose their audio information into frequency
bands and, after that, sonogram images with the same size are
generated. These images have been used to train and test different
convolutional neural network architectures. The best results
have been obtained with a modified version of the AlexNet model,
achieving 97% accuracy (specificity: 95.12%, sensitivity: 93.20%,
PhysioNet/CinC Challenge 2016 score: 0.9416). This tool could aid
cardiologists and primary care physicians in the auscultation process,
improving the decision making task and reducing type-I and
type-II errors.Ministerio de Economía y Competitividad TEC2016-77785-
Spike-based control monitoring and analysis with Address Event Representation
Neuromorphic engineering tries to mimic biological
information processing. Address-Event Representation (AER) is
a neuromorphic communication protocol for spiking neurons
between different chips. We present a new way to drive robotic
platforms using spiking neurons. We have simulated spiking
control models for DC motors, and developed a mobile robot
(Eddie) controlled only by spikes. We apply AER to the robot
control, monitoring and measuring the spike activity inside the
robot. The mobile robot is controlled by the AER-Robot tool,
and the AER information is sent to a PC using the
USBAERmini2 interface.Junta de Andalucía P06-TIC-01417Ministerio de Educación y Ciencia TEC2006-11730-C03-0
An AER-Based Actuator Interface for Controlling an Anthropomorphic Robotic Hand
Bio-Inspired and Neuro-Inspired systems or circuits are a
relatively novel approaches to solve real problems by mimicking the biology
in its efficient solutions. Robotic also tries to mimic the biology and
more particularly the human body structure and efficiency of the muscles,
bones, articulations, etc. Address-Event-Representation (AER) is
a communication protocol for transferring asynchronous events between
VLSI chips, originally developed for neuro-inspired processing systems
(for example, image processing). Such systems may consist of a complicated
hierarchical structure with many chips that transmit data among
them in real time, while performing some processing (for example, convolutions).
The information transmitted is a sequence of spikes coded using
high speed digital buses. These multi-layer and multi-chip AER systems
perform actually not only image processing, but also audio processing,
filtering, learning, locomotion, etc. This paper present an AER interface
for controlling an anthropomorphic robotic hand with a neuro-inspired
system.Unión Europea IST-2001-34124 (CAVIAR)Ministerio de Ciencia y Tecnología TIC-2003-08164-C03-0
NAVIS: Neuromorphic Auditory VISualizer Tool
This software presents diverse utilities to perform the first post-processing layer taking the neuromorphic auditory sensors (NAS) information. The used NAS implements in FPGA a cascade filters architecture, imitating the behavior of the basilar membrane and inner hair cells and working with the sound information decomposed into its frequency components as spike streams. The well-known neuromorphic hardware interface Address-Event-Representation (AER) is used to propagate auditory information out of the NAS, emulating the auditory vestibular nerve. Using the information packetized into aedat files, which are generated through the jAER software plus an AER to USB computer interface, NAVIS implements a set of graphs that allows to represent the auditory information as cochleograms, histograms, sonograms, etc. It can also split the auditory information into different sets depending on the activity level of the spike streams. The main contribution of this software tool is that it allows complex audio post-processing treatments and representations, which is a novelty for spike-based systems in the neuromorphic community and it will help neuromorphic engineers to build sets for training spiking neural networks (SNN).Ministerio de Economía y Competitividad TEC2012-37868-C04-0
