Neural Networks Reduction via Lumping

The increasing size of recently proposed Neural Networks makes it hard to implement them on embedded devices, where memory, battery and computational power are a non-trivial bottleneck. For this reason during the last years network compression literature has been thriving and a large number of solutions has been published to reduce both the number of operations and the parameters involved with the models. Unfortunately, most of these reducing techniques are actually heuristic methods and usually require at least one re-training step to recover the accuracy. The need of procedures for model reduction is well-known also in the fields of Verification and Performances Evaluation, where large efforts have been devoted to the definition of quotients that preserve the observable underlying behaviour. In this paper we try to bridge the gap between the most popular and very effective network reduction strategies and formal notions, such as lumpability, introduced for verification and evaluation of Markov Chains. Elaborating on lumpability we propose a pruning approach that reduces the number of neurons in a network without using any data or fine-tuning, while completely preserving the exact behaviour. Relaxing the constraints on the exact definition of the quotienting method we can give a formal explanation of some of the most common reduction techniques

A Relevance-Based CNN Trimming Method for Low-Resources Embedded Vision

A significant amount of Deep Learning research deals with the reduction of network complexity. In most scenarios the preservation of very high performance has priority over size reduction. However, when dealing with embedded systems, the limited amount of resources forces a switch in perspective. In fact, being able to dramatically reduce complexity could be a stronger requisite for overall feasibility than excellent performance. In this paper we propose a simple to implement yet effective method to largely reduce the size of Convolutional Neural Networks with minimal impact on their performance. The key idea is to assess the relevance of each kernel with respect to a representative dataset by computing the output of its activation function and to trim them accordingly. The resulting network becomes small enough to be adopted on embedded hardware, such as smart cameras or lightweight edge processing units. In order to assess the capability of our method with respect to real-world scenarios, we adopted it to shrink two different pre-trained networks to be hosted on general purpose low-end FPGA hardware to be found in embedded cameras. Our experiments demonstrated both the overall feasibility of the method and its superior performance when compared with similar size-reducing techniques introduced in recent literature

The ESC-EORP EURO-ENDO (European Infective Endocarditis) registry

Aims: The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) European Endocarditis (EURO-ENDO) registry aims to study the care and outcomes of patients diagnosed with infective endocarditis (IE) and compare findings with recommendations from the 2015 ESC Clinical Practice Guidelines for the management of IE and data from the 2001 Euro Heart Survey. Methods and results: Patients (n = 3116) aged over 18 years with a diagnosis of IE based on the ESC 2015 IE diagnostic criteria were prospectively identified between 1 January 2016 and 31 March 2018. Individual patient data were collected across 156 centres and 40 countries. The primary endpoint is all-cause mortality in hospital and at 1 year. Secondary endpoints are 1-year morbidity (all-cause hospitalization, any cardiac surgery, and IE relapse), the clinical, epidemiological, microbiological, and therapeutic characteristics of patients, the number and timing of non-invasive imaging techniques, and adherence to recommendations as stated in the 2015 ESC Clinical Practice Guidelines for the management of IE. Conclusion: EURO-ENDO is an international registry of care and outcomes of patients hospitalized with IE which will provide insights into the contemporary profile and management of patients with this challenging disease

Surgery and outcome of infective endocarditis in octogenarians: prospective data from the ESC EORP EURO-ENDO registry

none912Purpose: High mortality and a limited performance of valvular surgery are typical features of infective endocarditis (IE) in octogenarians, even though surgical treatment is a major determinant of a successful outcome in IE. Methods: Data from the prospective multicentre ESC EORP EURO-ENDO registry were used to assess the prognostic role of valvular surgery depending on age. Results: As compared to < 80 yo patients, ≥ 80 yo had lower rates of theoretical indication for valvular surgery (49.1% vs. 60.3%, p < 0.001), of surgery performed (37.0% vs. 75.5%, p < 0.001), and a higher in-hospital (25.9% vs. 15.8%, p < 0.001) and 1-year mortality (41.3% vs. 22.2%, p < 0.001). By multivariable analysis, age per se was not predictive of 1-year mortality, but lack of surgical procedures when indicated was strongly predictive (HR 2.98 [2.43-3.66]). By propensity analysis, 304 ≥ 80 yo were matched to 608 < 80 yo patients. Propensity analysis confirmed the lower rate of indication for valvular surgery (51.3% vs. 57.2%, p = 0.031) and of surgery performed (35.3% vs. 68.4%, p < 0.0001) in ≥ 80 yo. Overall mortality remained higher in ≥ 80 yo (in-hospital: HR 1.50[1.06-2.13], p = 0.0210; 1-yr: HR 1.58[1.21-2.05], p = 0.0006), but was not different from that of < 80 yo among those who had surgery (in-hospital: 19.7% vs. 20.0%, p = 0.4236; 1-year: 27.3% vs. 25.5%, p = 0.7176). Conclusion: Although mortality rates are consistently higher in ≥ 80 yo patients than in < 80 yo patients in the general population, mortality of surgery in ≥ 80 yo is similar to < 80 yo after matching patients. These results confirm the importance of a better recognition of surgical indication and of an increased performance of surgery in ≥ 80 yo patients.nonePazdernik, Michal; Iung, Bernard; Mutlu, Bulent;

Surgery and outcome of infective endocarditis in octogenarians: prospective data from the ESC EORP EURO-ENDO registry

Purpose: High mortality and a limited performance of valvular surgery are typical features of infective endocarditis (IE) in octogenarians, even though surgical treatment is a major determinant of a successful outcome in IE. Methods: Data from the prospective multicentre ESC EORP EURO-ENDO registry were used to assess the prognostic role of valvular surgery depending on age. Results: As compared to < 80 yo patients, ≥ 80 yo had lower rates of theoretical indication for valvular surgery (49.1% vs. 60.3%, p < 0.001), of surgery performed (37.0% vs. 75.5%, p < 0.001), and a higher in-hospital (25.9% vs. 15.8%, p < 0.001) and 1-year mortality (41.3% vs. 22.2%, p < 0.001). By multivariable analysis, age per se was not predictive of 1-year mortality, but lack of surgical procedures when indicated was strongly predictive (HR 2.98 [2.43–3.66]). By propensity analysis, 304 ≥ 80 yo were matched to 608 < 80 yo patients. Propensity analysis confirmed the lower rate of indication for valvular surgery (51.3% vs. 57.2%, p = 0.031) and of surgery performed (35.3% vs. 68.4%, p < 0.0001) in ≥ 80 yo. Overall mortality remained higher in ≥ 80 yo (in-hospital: HR 1.50[1.06–2.13], p = 0.0210; 1-yr: HR 1.58[1.21–2.05], p = 0.0006), but was not different from that of < 80 yo among those who had surgery (in-hospital: 19.7% vs. 20.0%, p = 0.4236; 1-year: 27.3% vs. 25.5%, p = 0.7176). Conclusion: Although mortality rates are consistently higher in ≥ 80 yo patients than in < 80 yo patients in the general population, mortality of surgery in ≥ 80 yo is similar to < 80 yo after matching patients. These results confirm the importance of a better recognition of surgical indication and of an increased performance of surgery in ≥ 80 yo patients
