The satisfied customer is in itself an advertisement that is more effective for others than any other strategy of marketing. Service needs to be designed in such a way as to make it easier for customers to know that the showroom is one of India's leading mobile car outlets. It has been active in promoting automotive mobile products for the past 10 years, but in the recent past since 2008, automotive sales have been dismal due to dissatisfaction among large group of customers due to deteriorating after-sales service quality. Absolutely in excess of 10 surveys will take. Information were taken for the most part through essential information. Be that as it may, organization and item profiles were alluded as well. An organized camouflaged meeting calendar was intended to gather information source. The timetable strategy was selected since the technique would help to compact measure of data. The inquiries comprise of shut – finished and open – finished once. Open – finished inquiries were posed to get the thoughts and recommendations from the respondents. Additionally, other than those referenced in the survey were approached to be determined. Shut - finished addresses included dichotomous, various decision and positioning question. Rating scale was likewise included. The example size is 120 . The gathered information have been broke down with the assistance of measurable apparatuses like, Simple rate strategy.

AbstractThe dimensionality of a network’s collective activity is of increasing interest in neuroscience. This is because dimensionality provides a compact measure of how coordinated network-wide activity is, in terms of the number of modes (or degrees of freedom) that it can independently explore. A low number of modes suggests a compressed low dimensional neural code and reveals interpretable dynamics [1], while findings of high dimension may suggest flexible computations [2, 3]. Here, we address the fundamental question of how dimensionality is related to connectivity, in both autonomous and stimulus-driven networks. Working with a simple spiking network model, we derive three main findings. First, the dimensionality of global activity patterns can be strongly, and systematically, regulated by local connectivity structures. Second, the dimensionality is a better indicator than average correlations in determining how constrained neural activity is. Third, stimulus evoked neural activity interacts systematically with neural connectivity patterns, leading to network responses of either greater or lesser dimensionality than the stimulus.Author summaryNew recording technologies are producing an amazing explosion of data on neural activity. These data reveal the simultaneous activity of hundreds or even thousands of neurons. In principle, the activity of these neurons could explore a vast space of possible patterns. This is what is meant by high-dimensional activity: the number of degrees of freedom (or “modes”) of multineuron activity is large, perhaps as large as the number of neurons themselves. In practice, estimates of dimensionality differ strongly from case to case, and do so in interesting ways across experiments, species, and brain areas. The outcome is important for much more than just accurately describing neural activity: findings of low dimension have been proposed to allow data compression, denoising, and easily readable neural codes, while findings of high dimension have been proposed as signatures of powerful and general computations. So what is it about a neural circuit that leads to one case or the other? Here, we derive a set of principles that inform how the connectivity of a spiking neural network determines the dimensionality of the activity that it produces. These show that, in some cases, highly localized features of connectivity have strong control over a network’s global dimensionality—an interesting finding in the context of, e.g., learning rules that occur locally. We also show how dimension can be much different than first meets the eye with typical “pairwise” measurements, and how stimuli and intrinsic connectivity interact in shaping the overall dimension of a network’s response.

Compact measures, i.e. measures that are inner-regular with respect to a compact family of sets, are related to measurable weak sections in the same way as semicompact measures are related to disintegration. This enables us to prove several stability properties of the class of compact measures. E.g., a countable sum of compact measures is compact; the image $\nu$ of a compact measure $\mu$ is compact provided $\mu$ is an extremal preimage measure of $\nu$. As a consequence, we show that every tight Baire measure is compact.

A probability space is compact in the sense of Marczewski if and only if it admits countably additive disintegrations. It follows that the restriction of a compact measure to a sub-$\sigma$-algebra is compact.
