Rapid adaptation and efficient coding
Biosystems, 2002Rapid adaptation is a prominent feature of biological neuronal systems. From a functional perspective the adaptation of neuronal properties, namely the input-output relation of sensory neurons, is usually interpreted as an adaptation of the sensory system to changing environments as characterized by their stimulus statistics.

ECG Compression by Efficient Coding
2007The continuous demand for high performance and low cost electrocardiogram (ECG) processing systems have required the elaboration of more and more efficient and reliable ECG compression techniques. Such techniques face a tradeoff between compression ratio and retrieved quality, where the decrease of the last can compromise the subsequent use of the ...

The prior art construction of sets of balanced codewords by Knuth is attractive for its simplicity and absence of look-up tables, but the redundancy of the balanced codes generated by Knuth's algorithm falls a factor of two short with respect to the minimum required.

Coding for Efficient DNA Synthesis
2020 IEEE International Symposium on Information Theory (ISIT), 2020For DNA data storage to become a feasible technology, all aspects of the encoding and decoding pipeline must be optimized. Writing the data into DNA, which is known as DNA synthesis, is currently the most costly part of existing storage systems. As a step toward more efficient synthesis, we study the design of codes that minimize the time and number of

Efficient Coding for Interactive Communication
IEEE Transactions on Information Theory, 2014We revisit the problem of reliable interactive communication over a noisy channel and obtain the first fully (randomized) efficient constant-rate emulation procedure for reliable interactive communication. Our protocol works for any discrete memoryless noisy channel with constant capacity and fails with exponentially small probability in the total ...

Neural Computation, 1996
In 1969 Barlow introduced the phrase “economy of impulses” to express the tendency for successive neural systems to use lower and lower levels of cell firings to produce equivalent encodings. From this viewpoint, the ultimate economy of impulses is a neural code of minimal redundancy. The hypothesis motivating our research is that energy expenditures,

Efficient approximate adaptive coding
Proceedings DCC '97. Data Compression Conference, 2002We describe a mechanism for approximate adaptive coding that makes use of deferred probability update to obtain good throughput rates with no buffering of symbols from the input message. Our proposed mechanism makes use of a novel code calculation process that allows an approximate code for a message of m symbols to be calculated in O(log m) time ...

Efficient codes and balanced networks
Nature Neuroscience, 2016Recent years have seen a growing interest in inhibitory interneurons and their circuits. A striking property of cortical inhibition is how tightly it balances excitation. Inhibitory currents not only match excitatory currents on average, but track them on a millisecond time scale, whether they are caused by external stimuli or spontaneous fluctuations.

Codes with efficient erasure correction
2020Distributed storage systems are becoming increasingly ubiquitous in the emerging era of Internet of Things. Major internet technology companies employ large-scale distributed storage systems to accommodate the massive amounts of data generated and requested by global users. The need of reliable and efficient storage of immense amounts of data calls for
