Mean squared error

dereverberation (HERB) methods, which modeled RIR inverse filters as a ratio of the direct path component to the received signal. The design of the inverse filters exploited the harmonicity characteristics of the speech signal and estimated the filter coefficients in two distinct methods - one method estimated the average filter that transformed reverberant signals into harmonic signals, while the other method used a minimum mean squared error criterion that evaluated the quasi-periodicity of target signals. HERB algorithms take relatively longer time to converge, which also makes them difficult to use in real time processing. Linear predictive multi-input equalization (LIME) algorithm was used in [17] to achieve muti-channel dereverberation. The whitened speech residuals from the LIME output was mixed with the estimation of source auto regressive polynomials to obtain clean…

Performance Evaluation In order to assess the model accuracy, it is necessary to use some quantitative measures of learning. In this study the Mean Squared Error (MSE) and regression analysis were used to evaluate the model performance. MSE is a useful measure of success for numeric prediction and is calculated using Eq. (1). It is worth mentioning that small values of MSE indicate better performance of the ANN model. It was found that the optimum performance of the model is at 25 neurons with…

There are several errors in judgment that individuals make on a day to day basis. Everyone is guilty of making these errors regardless of their background, education, and life experiences. The common errors of judgment found in humans that I chose are Snap Judgment, Projection, and Sweeping Generalizations (Bethel University, 2013). Snap Judgment is a common error that I recognize or experience probably most often. An example would be the cop shootings on “innocent citizens”. The media and…

The results from the experiment generally show the trials with full light intensity to have produced more oxygen, showing the elodea samples to have photosynthesised more than the lower light intensity trials. Trials 1 and 2 were in water bath 1 with full light intensity, whereas Trials 3 and 4 were in water bath 2, with lower light intensity. Experimental error caused the trials with the lower light intensity to be disrupted, and no data was collected for these trials on Day 8 of the…

Human error is prevalent throughout all of life. Even when presented with the easiest of instructions, humans tend to mess it up. Though many of these mistakes come from failure or misunderstandings, there are other instances in which over-analysis comes into play. In Victor Hugo’s novel, Les Miserables, we are introduced to one such character. This man’s name was Jean Valjean. Although a former convict, Valjean was presented with an opportunity to change his life for the better. Very few…

At my practicum, there are several opportunities for a counselor to make a mistake. However, the mistakes can be easily corrected, and most of the time the person on the other end of the phone or computer will not be phased by a slip up. The forgiveness of the mess up does not make it okay, because as social workers we should strive to always provide the best services for our clients. When I think of decisions I have made that were flawed, I immediately think of a chat session I had last week…

at describing and expressing my own feeling and experience. This assignment was a detailed version of my photo essay. The TA feedback from the photo essay guided me to explore extra areas in my scout experience. Despite no peer reviews, TA’s opinion helped me a lot in writing this assignment. I reviewed the essay after the first submission, I have addressed my common errors and change some wordings. At the same time, I deleted some unrelated and redundant information to my experience in…

Accidents happen, yes. But it keeps re-occuring over the last decades or so. Also the cause of accidents are very similar to each other, mainly due to systematic failures, human errors and such. How come we still fail to learn from the causes to prevent it form happenening again? There are a lot of reasearch that shows how human errors and systematic failures cause accidents. Over the last 40 years or so, the shipping industry has focused on improving ship structures, reliability and safety of…

abide, but thats human nature. We all make mistakes and the only determination of whether or not any disciplinary action takes place is whether or not we get caught. That being said, its not about getting caught or being reprimanded. The only thing that matters is knowing before you make that mistake that what you are about to do is wrong and being able to stop. The saying, “nobody is perfect” really is true. I have been blessed with strong supporters and great guidance throughout my whole…

live, they constantly question if life would be different if that mistake never happened. Curiosity is especially evident in “Christmas with Grandfather” and “The Unknown Errors of Our Lives” by Chitra…
