Exploration in non-stationary bandits
The actual reward earned on an individual trial was given by a sample from a Gaussian distribution with the current mean, and a standard deviation of 4.
Exploration in non-stationary bandits
In addition, when the discount parameter is larger (7 = 0.90 vs 7 = 0.99) the algorithm samples more often, consistent with the larger difference in utility for a given standard deviation for larger discount parameters (Fig.
Information sampling
Standard deviation option 1
Information sampling
Utility as a function of mean of option 1 and mean of option 2, with standard deviation of both options set to 4 and discount rate, v = 0.90.
Information sampling
Utility as a function of standard deviation for 2 discount values when mean is 50 for both options and standard deviation is 4 for option 2.
Markov decision processes
For the non-stationary two-armed bandit, the means were fit with a 3rd order B-spline, and the standard deviations were fit with a 2nd order piecewise polynomial.
Markov decision processes
The node locations for the standard deviations were given by 0.25, 1, 3, 5, and 15.
Markov decision processes
The standard deviations were evaluated at 0.5, 1, 2, 3, 4, 5, 7 and 14.
Task specific details of the MPD models
Therefore the information space for this POMDP, equivalent to the state space for the MDP, can be compactly represented: bt = ([11, 61, [12, 62) as the estimated mean and standard deviation (or variance) of each bandit.
Task specific details of the MPD models
This integral was calculated numerically by discretizing y over +/- 2 standard deviations , and sampling 10 points.

Microarray metadataset
Instead, we found that the best approach was to convert the values in each time series to Z-scores—i.e., for each gene in each dataset, we subtract its mean eXpression level and divide by its standard deviation .
Microarray metadataset
To prevent the need to recalculate the null distribution for every pattern of NAs in the data for empirical ITK_CYCLE (there were 5005 unique NA permutations in the data), the NAs were replaced by random noise drawn from a Gaussian distribution with mean and standard deviation that match those of the data on the whole.
Simulated data benchmarks
3A we generated 10,000 time series with uniformly distributed random phase shifts (always with a 24 h period) and added Gaussian noise to each point with a standard deviation of 25% or 50% of the total waveform amplitude, examples of which can be seen in Fig.
Simulated data benchmarks
(B) Cosine in black, with Gaussian noise with standard deviation of 25% (blue) or 50% (green) of amplitude.
Simulated data benchmarks
We added Gaussian noise with a standard deviation of either 25% or 50% of the amplitude of the time series, as previously described.
Supporting Information
AUROCs for simulated data with 25% noise ( standard deviation of Gaussian noise as a percent of amplitude).

Detection of artificial EPSCs immersed in fluctuating noise
We injected into layer 2/3 pyramidal cells current consisting of three components: simulated, artificial excitatory postsynaptic current (aEPSC) from a single presynaptic neuron, fluctuating noise with standard deviation 0, and a DC offset (Fig.
Detection of artificial EPSCs immersed in fluctuating noise
After this adjustment, the overall standard deviation of the scaled fluctuating current awas between 70 and 110pA.
Experiment 1. Partially-defined input: Artificial EPSCs immersed in fluctuating noise
Current for injection in this first set of experiments was composed of 1) a fluctuating component 017(t), where 17(t) is a standardized (zero mean, unit variance) Ornstein-Uhlenbeck (OU) process with a correlation time of T = 5ms rescaled to have standard deviation 0, 2) artificial EPSCs of several different amplitudes: 0.1, 0.2, 0.25, 0.3, 0.5, 1.0 and 1.5 of the noise standard deviation 0, and 3) a DC component tuned to maintain a desired firing rate, around ~ 5 Hz.

Data segmentation
In addition Gaussian fit of the resulting delay histograms for values 0.85 g VC 3 0.95 did not show significant differences either in the standard deviation or the 95% confidence interval from a Gaussian fit of Fig.
Results
Breakdown of the original spatio-temporal data into the individual and paired flight trajectories together with mean and standard deviation values of the temporal and spatial length as well as speed of all flights.

Computing the mean and standard deviations we obtain 349.4° and 169.4°, (i33.1°), for the individual flying bats and 348.0° and 168.0°, (i36.7°), for the paired flying bats.

Network-based prediction of DrugBank ligand and human target pairs
The “Global Z-score” (G2) is obtained by running the predictions of all drugs present in DrugBank against all targets, obtaining a global mean (1m) and a global standard deviation (CG) to Z-score a specific predicted pair.
Network-based prediction of DrugBank ligand and human target pairs
The “Local Z-score” (L2), is similarly calculated by running the predictions of all drugs present in DrugBank retrieving the mean (1,4 L) and the standard deviation (CL) of the score for a specific target.
