What is selective sampling?4 answersSelective sampling is an online learning framework where the learner chooses data samples whose labels can maximize performance and only queries the labels of those chosen samples. It has been extensively studied for independent data samples, but there is limited exploration in the context of graphs. In the problem of best-arm identification, selective sampling involves choosing whether to take a measurement or wait for a potentially more informative point. In error recovery for digital data channels, selective sampling involves saving samples with the best metric measure during each step of recovery. In matrix completion, selective sampling allows for designing the observation set based on the structure of the matrix. In deep neural network training, selective sampling involves using a measurement called the minimal margin score to accelerate the training process.
What is sampling method?4 answersSampling method is a statistical technique used to select a subset or sample from a population for the purpose of making observations and drawing inferences about the entire population. It is a way to study a representative group of individuals when studying the entire population is not feasible or practical. Sampling helps to reduce cost, time, and workload while still providing high-quality information that can be extrapolated to the population. It is important for the sample to be a true representation of the population in order for the inferences to be applicable. Using sampling techniques helps to eliminate bias in the selection process.
What is the Sampling?4 answersSampling is a statistical method used to select a subset or sample from a population for the purpose of making observations and drawing inferences about the entire population. It is a way to study a representative group of individuals when studying the entire population is not feasible. The sample should be a true representation of the population to ensure that the inferences made from the analysis can be applied to the population. Sampling techniques eliminate bias in choosing the subset. Sampling is integral to research and has implications on the quality of research findings. In quantitative research, sampling focuses on maximizing the statistical representativeness of a population, while in qualitative research, it focuses on complete representation of a phenomenon of interest. Probability sampling, where all individuals have an equal chance of being selected, is ideal but often not practical. Non-probability sampling, such as convenience sampling, is more common. Careful planning and consideration of sample size are important in both types of research. Sampling involves selecting a subset of the population for study due to time, cost, and other constraints. It allows for accurate and reliable information while reducing time and cost. However, there are disadvantages such as inadequate samples, bias, accuracy problems, and sampling errors. Different sampling techniques, such as non-probability and probability sampling, are used to make the samples representative of the population. Sampling is the selection of a subset of the population of interest in a research study. It is a practical way to collect data faster and at a lower cost than attempting to reach every member of the population. Understanding the means by which the data arrived in the database is important for analyzing and drawing conclusions from the data. A sampling device is a tool that includes update circuits and a selection circuit to select a set of values from a plurality of state variables. The update circuits calculate change values and update the values of the state variables and local fields. The selection circuit selects a set of values based on score values and outputs the selected set.
What is sampling technique?5 answersSampling technique is a method used in research to select a subset of individuals or data points from a larger population or dataset. It is an important tool in various fields such as social sciences, design of experiments, image processing, and data analysis. There are different types of sampling techniques, including probability and non-probability sampling. Probability sampling involves randomly selecting individuals or data points, while non-probability sampling involves selecting individuals or data points based on specific criteria. Sampling is used to draw reliable and trustworthy results from a large population or dataset. It is also used to reduce the volume of data to be processed in situations with large and complex data. Various tools and techniques from statistics, mathematics, machine learning, and deep learning are used to address the challenges of sampling complex data.
What is the definition of sampling in research?3 answersSampling in research refers to the process of selecting a subset of individuals or elements from a larger population to represent that population in a study. It is used when it is not feasible or practical to study the entire population. Sampling can be done in a systematic manner to ensure validity and avoid errors such as lack of representation, selection bias, and lack of precision. There are different types of sampling methods, including probability sampling and non-probability sampling. Probability sampling involves randomly selecting individuals from the population, while non-probability sampling involves selecting individuals based on specific criteria or convenience. The choice of sampling method depends on the research objectives and the type of analysis being conducted. Sampling is used in both qualitative and quantitative research, with different considerations for determining sample size and achieving generalizability or saturation of themes.
What is the percentile for the criteria in criterion sampling?5 answersThe percentile for the criteria in criterion sampling is used to progressively reinforce lower levels of breath carbon monoxide (CO) in hard-to-treat (HTT) smokers. This percentile criterion facilitates longer periods of smoking abstinence and participants receiving incentives for lower breath CO levels on percentile schedules typically earn more for their first abstinent breath CO sample relative to participants receiving incentives only for smoking abstinence. However, in a study comparing percentile and fixed criterion schedules, it was found that percentile incentive schedules were not associated with longer periods of abstinence relative to fixed criterion incentive schedules. Further studies are needed to test whether the difference between studies is due to initial incentive magnitude.
