Science Experiments: Reproducibility and Reliability

Reproducibility of scientific results is a very important part of the scientific method.

The first step is to show that a particular phenomenon occurs, and this is usually done by describing a simple experimental setup that produces it. This is then followed by an investigation into why the phenomenon occurs in some more complex situation. An example of this might be the study of the motion of a billiard ball with friction. This would describe the basic setup, and then the results of this experiment would be used to try to understand why friction affects how balls move.

This procedure is similar to that employed by chemists, biologists, psychologists, engineers etc. It’s important to remember that science is not an absolute truth, but a process for investigating the natural world. Therefore it’s quite possible that scientists will at times produce results that they aren’t able to explain or reproduce. This is a normal part of science and doesn’t mean that the results are false. It just means that there’s more to learn.

In order to make sure that the results of a scientific experiment are reliable and repeatable, it’s important that they are done as carefully as possible. There are many factors which may affect the outcome of an experiment:

· The accuracy of the equipment used in an experiment is one thing that can affect the validity of the results. For example, a scale that’s only accurate to one gram will probably be less useful than one that can measure down to 0.01g.

· The experiment should be done in a controlled environment so that extraneous factors can be minimised or eliminated. This sort of thing is especially important if the experiment is meant to be a comparative one, where different factors are being tested.

· The experiment should have controls used in it. These would be things that you can vary or change, but which shouldn’t affect the results of your experiment. This will allow you to eliminate variables from the experiment. A simple example might be dividing a test group into two halves, and then testing each half for some characteristic of interest to you. The height of the participants in the first half could be used as a control variable, so that you can compare their results with those of the shorter members of the second group.

· The experiment needs to be repeatable. This means that it should be possible for other scientists to do an identical experiment, and get the same results as you did. If someone else can’t reproduce your results, then they have no way of knowing if yours are correct or not.

If you’re going to do a science experiment, then it’s very important that you find out as much about how the equipment and other things work as you can. It’s also very important to do your research properly — don’t just take the results of someone else’s experiment at face value! If there are no explanations for why something happened, then it’s probably best to assume that you don’t know why it happened!

But in certain areas of sciences experiments are quite tough to reproduce either due to the nature of the experiment or due to the fact that an investigator has used exotic equipment, which is very expensive and hard to get hold of.

Science experiments are repeatable and reliable because scientists follow standardized procedures for their experiments. The results obtained from one scientist’s experiment are usually reproducible by another scientist using the same procedures. The reliability of scientific experiments is due to the fact that scientists control their variables and try as hard as possible to eliminate any extraneous factors.

However, the procedure followed for a particular experiment may be very complex and difficult to understand. Most scientists do not have time or inclination to explain in detail why they took the steps that they did for their experiments. This can make it very difficult to repeat an experiment or verify its results independently.

A good example of this is Einstein’s Theory of Relativity, which has been verified by astronomical observations and other experiments but is still not easy to understand or explain in detail. In this example, the experimental results of Einstein’s theory were not that difficult to verify because they did not require very expensive equipment.

In the field of Machine Learning and particularly Deep Learning, there are many experiments showing some amazing results. One of the recent examples is a paper by Google DeepMind which shows a technique called “one-shot” learning, where a machine can be trained to recognize an object after seeing it only once. The research paper is titled “One Shot Learning with Memory-Augmented Neural Networks” and is available here. The experiment that the researchers carried out to achieve these results was very simple in nature, but it shows how powerful Deep Learning techniques can be. However, to reproduce the results of this experiment is not easy. The software used for the experiment is available at https://github.com/google/deepmind-one-shot (corrected link: https://deepmind.com/research/publications/one-shot-learning-memory-augmented-neural-networks) but it requires a lot of time and effort to install and setup on your own computer.

Despite the limitations, there are still a lot of machine learning experiments which can be replicated. One such experiment, which is described in detail here, shows how we can train a neural network to recognize hand written digits from the MNIST database. The experiment also includes the source code that you can use for training and evaluating your own neural networks on the MNIST database. I highly recommend everyone to try out this experiment and compare their results with the ones shown in the paper.

The results of a scientific experiment may not be reproducible or repeatable, because it’s very difficult to eliminate all of the extraneous factors that might affect an experiment. However, if an experiment is very simple, then it’s possible that the results can be reproduced in a different environment.

If you want to reproduce a scientific result, then it’s best to work from the original paper rather than just copying someone else’s results. It may take some time and effort to get familiar with the details of the experiment, but it will help you to understand why someone got a particular result.
