Techniques for reducing variance
• Add more training data : This is the simplest and most reliable way to address variance, so long as you have access to significantly more data and enough computational power to process the data. • Add regularization (L2 regularization, L1 regularization, dropout): This technique reduces variance but increases bias.

Small screening design when the overall variance is unknown
Simulation results are provided to demonstrate that the proposed design achieves a more reliable estimate of error variance, as well as a reliable significant test. Furthermore, we study the optimal follow-up plan. Relevant optimality theories are established and a convenient construction method for optimal follow-up design is proposed.

Screening Designs and Design Evaluation
How to lower variance using design 1. Replicate or otherwise add runs to a design 2. For continuous factors, increase the range between high and low settings 3. Use blocking, i.e. run your experiment in homogeneous groups of runs 4. Reduce or eliminate correlation between factors How to lower bias using design 1. Randomize the run order 2.

An effective screening design for sensitivity analysis of …
The variance-based analysis fully confirms the EE results, since for all the outputs the first group of factors accounts for less than 1% of the total variance. This corroborates the fitness of the EE method for use as a screening technique in models with multiple outputs and many input factors. 6. Conclusions

screening design reducing variance. variance as possible. The variance that you can explain is the variance due to being in the positive versus negative feedback condition. This is the variance between the means of the two groups: 43.6 versus 38.6. You can explain that variance because you have an independent variable – "feedback. Read More

Reducing Variance
As a result, variance cannot be complacently accepted, even if it is a part of human nature. By standardizing our operations, we can greatly reduce variances. For example, the use of ruler or other measuring devices can improve our quality. If you have employees that cut or measure, make sure they have rulers and measuring cups.
