The 1839 Austin city plan (commonly known as the Waller Plan) is the original city plan for the development of Austin, Texas, which established the grid plan for what is now downtown Austin. It was commissioned in 1839 by the government of the Republic of Texas and developed by Edwin Waller, a Texian revolutionary and ... | https://en.wikipedia.org/wiki/Waller_Plan |
In January 1839 the Congress of the Republic of Texas appointed a committee to select a site for a new planned capital for the republic. Texas President Mirabeau B. Lamar instructed the committee to consider a site along the north bank of the Colorado River that he had visited the previous year. The committee was pleas... | https://en.wikipedia.org/wiki/Waller_Plan |
Waller selected a 1-mile (1.6 km) square tract on the north shore of the Colorado, sitting roughly between the mouths of two smaller streams entering the river (now known as Shoal Creek and Waller Creek). Assisted by surveyors L. J. Pilie and Charles Schoolfield, Waller divided the 640-acre (260 ha) tract into a grid p... | https://en.wikipedia.org/wiki/Waller_Plan |
Another major street, College Avenue (now 12th Street), ran to the Capitol Square from the west and east; both of these avenues were laid 120 feet (37 m) wide.

There are eight possible combinations to render the various trigrams (八卦 bāguà): | https://en.wikipedia.org/wiki/Bagua |
Book of Changes listed two sources for the eight trigrams. The chapter Xì Cí shàng; 'The Great Treatise I' explains the first source thus: This explanation would later be modified to: The Limitless (Wuji) produces the delimited, and this is the Absolute (Taiji). The Taiji produces two forms, named Yin and Yang. | https://en.wikipedia.org/wiki/Bagua |
The two forms produce four phenomena, named lesser yang, great yang (tai yang also means the Sun), lesser yin, great yin (tai yin also means the Moon).

The Bagua is an essential tool in the majority of Feng Shui schools. The Bagua used in Feng shui can appear in two different versions: the Earlier Heaven Bagua, used for burial sites, and the Later Heaven Bagua, used for the residences. | https://en.wikipedia.org/wiki/Bagua |
In Primordial Bagua, also known as Fu Xi Bagua or Earlier Heaven Bagua, the Heaven is in the higher part and the Earth is in the lower part. The trigram Qian (Heaven) is at the top, the trigram Kun (Earth) is at the bottom (in the past, the South was located at the top in Chinese maps). The trigram Li (Fire) is located... | https://en.wikipedia.org/wiki/Bagua |
Gen (Mountain) and Dui (Lake) form the last pair, one opposite the other, both in balance and harmony. The adjustment of the trigrams is symmetrical by forming exact contrary pairs. They symbolize the opposite forces of Yin and Yang and represent an ideal state, when everything is in balance. | https://en.wikipedia.org/wiki/Bagua |
The sequence of the trigrams in Manifested Bagua, also known as the Bagua of King Wen or Later Heaven Bagua, describes the patterns of the environmental changes. Kan is placed downwards and Li at the top, Zhen in the East and Dui in the West. Contrary to the Earlier Heaven Bagua, this one is a dynamic Bagua where energ... | https://en.wikipedia.org/wiki/Bagua |
Feng shui was made very popular in the West thanks to the Bagua of the eight aspirations. Each trigram corresponds to an aspect of life which, in its turn, corresponds to one of the cardinal directions. Applying feng shui using the Bagua of the eight aspirations (or Bagua map for short) made it possible to simplify fen... | https://en.wikipedia.org/wiki/Bagua |
Western Bagua focuses more heavily on the power of intention than the traditional forms of feng shui.Masters of traditional feng shui disregard this approach, for its simplicity, because it does not take into account the forms of the landscape or the temporal influence or the annual cycles. The Bagua of the eight aspir... | https://en.wikipedia.org/wiki/Bagua |
A bagua map is a tool used in Western forms of feng shui to map a room or location and see how the different sections correspond to different aspects in one's life.

An open-ended question is a question that cannot be answered with a "yes" or "no" response, or with a static response. Open-ended questions are phrased as a statement which requires a longer response. The response can be compared to information that is already known to the questioner. | https://en.wikipedia.org/wiki/Open-ended_question |
Examples of open-ended questions include: Tell me about your relationship with your supervisor. How do you see your future? Tell me about the children in this photograph. What is the purpose of government? Why did you choose that answer? | https://en.wikipedia.org/wiki/Open-ended_question |
The received wisdom in education is that open questions are broadly speaking 'good' questions. They invite students to give longer responses that demonstrate their understanding. They are preferable to closed questions (i.e. one that demands a yes/no answer) because they are better for discussions or enquiries, whereas... | https://en.wikipedia.org/wiki/Open-ended_question |
This is based on Worley's central arguments that there are two different kinds of open and closed questions: grammatical and conceptual. He argues that educational practitioners should be aiming for questions that are "grammatically closed, but conceptually open". For example, in standard parlance, 'is it ever right to... | https://en.wikipedia.org/wiki/Open-ended_question |
would be regarded as a closed question: it elicits a yes/no response. Significantly, however, it is conceptually open. Any initial yes/no answer to it can be 'opened up' by the questioner ('why do you think that?,' 'Could there be an instance where that's not the case? | https://en.wikipedia.org/wiki/Open-ended_question |
), inviting elaboration and enquiry. This grammatically closed but cognitively open style of questioning, Worley argues, "gives the best of both worlds: the focus and specificity of a closed question (this, after all, is why teachers use them) and the inviting, elaborating character of an open question". Closed questi... | https://en.wikipedia.org/wiki/Open-ended_question |
Worley's structural and semantic distinction between open and closed questions is integral to his pedagogical invention 'Open Questioning Mindset', or OQM. OQM refers to the development, in educators, of an open attitude towards the process of learning and the questioning at the heart of that process. It is a mind-set ... | https://en.wikipedia.org/wiki/Open-ended_question |
Teachers who develop an Open Questioning Mindset listen openly for the cognitive content of student's contributions and looks for ways to use what is given for learning opportunities, whether right, wrong, relevant or apparently irrelevant. OQM encourages a style of pedagogy that values genuine enquiry in the classroom... | https://en.wikipedia.org/wiki/Open-ended_question |

Vacuum activities (or vacuum behaviours) are innate, fixed action patterns (FAPs) of animal behaviour that are performed in the absence of a sign stimulus (releaser) that normally elicit them. This type of abnormal behaviour shows that a key stimulus is not always needed to produce an activity. Vacuum activities often ... | https://en.wikipedia.org/wiki/Vacuum_activity |
From Latin vacuum (an empty space, void) noun use of neuter of vacuus (empty) related to vacare (be empty). | https://en.wikipedia.org/wiki/Vacuum_activity |
The term was first established by the ethologist Konrad Lorenz in the 1930s after observations of a hand-raised starling. In 1937 Lorenz wrote: "With head and eyes the bird made a motion as though following a flying insect with its gaze; its posture tautened; it took off, snapped, returned to its perch, and with its bi... | https://en.wikipedia.org/wiki/Vacuum_activity |
Animals that were raised without releasing instinctual behaviours, due to being in captivity or being taken as a pet, will produce these vacuum behaviours in seemingly random moments due to a build-up of energy reserves. This theory is based on Lorenz's Hydraulic Model of Motivation, which attempts to explain the mecha... | https://en.wikipedia.org/wiki/Vacuum_activity |
Over time as animals have evolved, natural selection has favoured some behaviours over others because they have ensured the survival and reproduction of the animal. These potentially long-lasting, innate behaviours have a genetic origin that propagates through evolutionary time, becoming slightly altered due to environ... | https://en.wikipedia.org/wiki/Vacuum_activity |
Lorenz observed that a starling bird snapped at the air when flying as if it were catching insects though there were no real insects there.Weaver birds go through complicated nest building behaviour when there is no nest building material present.Sham dustbathing (sometimes referred to as "vacuum dustbathing") is a beh... | https://en.wikipedia.org/wiki/Vacuum_activity |
Wild raccoons often investigate their food by rubbing it between their paws while holding the food underwater, giving the appearance of 'washing' the food (although the exact motivation for this behaviour is disputed). Captive raccoons sometimes perform these actions of 'washing' their food by rubbing it between their ... | https://en.wikipedia.org/wiki/Vacuum_activity |
One vacuum activity that has been studied is 'tongue-rolling' by calves. Calves raised for 'white' veal are generally fed a milk-like diet from birth until they are slaughtered at about four months of age. The calves are prevented from consuming roughage such as grass or hay partly because the iron contained in such pl... | https://en.wikipedia.org/wiki/Vacuum_activity |
A similar vacuum activity to tongue rolling is 'vacuum chewing' by pigs. In this behaviour, pigs perform all the activities associated with chewing but with no substrate in their mouth. This abnormal behaviour can represent 52–80% of all stereotyped behaviours. | https://en.wikipedia.org/wiki/Vacuum_activity |
In mathematical modeling, overfitting is "the production of an analysis that corresponds too closely or exactly to a particular set of data, and may therefore fail to fit to additional data or predict future observations reliably". An overfitted model is a mathematical model that contains more parameters than can be ju... | https://en.wikipedia.org/wiki/Underfitting |
: 45 Underfitting occurs when a mathematical model cannot adequately capture the underlying structure of the data. An under-fitted model is a model where some parameters or terms that would appear in a correctly specified model are missing. | https://en.wikipedia.org/wiki/Underfitting |
Under-fitting would occur, for example, when fitting a linear model to non-linear data. Such a model will tend to have poor predictive performance. The possibility of over-fitting exists because the criterion used for selecting the model is not the same as the criterion used to judge the suitability of a model. | https://en.wikipedia.org/wiki/Underfitting |
For example, a model might be selected by maximizing its performance on some set of training data, and yet its suitability might be determined by its ability to perform well on unseen data; then over-fitting occurs when a model begins to "memorize" training data rather than "learning" to generalize from a trend. As an ... | https://en.wikipedia.org/wiki/Underfitting |
Such a model, though, will typically fail severely when making predictions. The potential for overfitting depends not only on the number of parameters and data but also the conformability of the model structure with the data shape, and the magnitude of model error compared to the expected level of noise or error in the... | https://en.wikipedia.org/wiki/Underfitting |
In particular, the value of the coefficient of determination will shrink relative to the original data. To lessen the chance or amount of overfitting, several techniques are available (e.g., model comparison, cross-validation, regularization, early stopping, pruning, Bayesian priors, or dropout). The basis of some tech... | https://en.wikipedia.org/wiki/Underfitting |
In statistics, an inference is drawn from a statistical model, which has been selected via some procedure. Burnham & Anderson, in their much-cited text on model selection, argue that to avoid overfitting, we should adhere to the "Principle of Parsimony". The authors also state the following. : 32–33 Overfitted models …... | https://en.wikipedia.org/wiki/Underfitting |
False treatment effects tend to be identified, and false variables are included with overfitted models. … A best approximating model is achieved by properly balancing the errors of underfitting and overfitting. Overfitting is more likely to be a serious concern when there is little theory available to guide the analysi... | https://en.wikipedia.org/wiki/Underfitting |
The book Model Selection and Model Averaging (2008) puts it this way. Given a data set, you can fit thousands of models at the push of a button, but how do you choose the best? With so many candidate models, overfitting is a real danger. Is the monkey who typed Hamlet actually a good writer? | https://en.wikipedia.org/wiki/Underfitting |
In regression analysis, overfitting occurs frequently. As an extreme example, if there are p variables in a linear regression with p data points, the fitted line can go exactly through every point. For logistic regression or Cox proportional hazards models, there are a variety of rules of thumb (e.g. 5–9, 10 and 10–15 ... | https://en.wikipedia.org/wiki/Underfitting |
The bias–variance tradeoff is often used to overcome overfit models. With a large set of explanatory variables that actually have no relation to the dependent variable being predicted, some variables will in general be falsely found to be statistically significant and the researcher may thus retain them in the model, t... | https://en.wikipedia.org/wiki/Underfitting |
Usually a learning algorithm is trained using some set of "training data": exemplary situations for which the desired output is known. The goal is that the algorithm will also perform well on predicting the output when fed "validation data" that was not encountered during its training. Overfitting is the use of models ... | https://en.wikipedia.org/wiki/Underfitting |
Such a function requires only three parameters (the intercept and two slopes). Replacing this simple function with a new, more complex quadratic function, or with a new, more complex linear function on more than two independent variables, carries a risk: Occam's razor implies that any given complex function is a priori... | https://en.wikipedia.org/wiki/Underfitting |
For example, it is nontrivial to directly compare the complexity of a neural net (which can track curvilinear relationships) with m parameters to a regression model with n parameters.Overfitting is especially likely in cases where learning was performed too long or where training examples are rare, causing the learner ... | https://en.wikipedia.org/wiki/Underfitting |
It's easy to construct a model that will fit the training set perfectly by using the date and time of purchase to predict the other attributes, but this model will not generalize at all to new data, because those past times will never occur again. Generally, a learning algorithm is said to overfit relative to a simpler... | https://en.wikipedia.org/wiki/Underfitting |
Everything else being equal, the more difficult a criterion is to predict (i.e., the higher its uncertainty), the more noise exists in past information that needs to be ignored. The problem is determining which part to ignore. A learning algorithm that can reduce the risk of fitting noise is called "robust." | https://en.wikipedia.org/wiki/Underfitting |
The most obvious consequence of overfitting is poor performance on the validation dataset. Other negative consequences include: A function that is overfitted is likely to request more information about each item in the validation dataset than does the optimal function; gathering this additional unneeded data can be exp... | https://en.wikipedia.org/wiki/Underfitting |
At the other extreme are models that can be reproduced only by exactly duplicating the original modeler's entire setup, making reuse or scientific reproduction difficult. It may be possible to reconstruct details of individual training instances from an overfitted machine learning model's training set. This may be unde... | https://en.wikipedia.org/wiki/Underfitting |
The optimal function usually needs verification on bigger or completely new datasets. There are, however, methods like minimum spanning tree or life-time of correlation that applies the dependence between correlation coefficients and time-series (window width). Whenever the window width is big enough, the correlation c... | https://en.wikipedia.org/wiki/Underfitting |
Underfitting is the inverse of overfitting, meaning that the statistical model or machine learning algorithm is too simplistic to accurately capture the patterns in the data. A sign of underfitting is that there is a high bias and low variance detected in the current model or algorithm used (the inverse of overfitting:... | https://en.wikipedia.org/wiki/Underfitting |
Shown in Figure 5 the linear line could not represent all the given data points due to the line not resembling the curvature of the points. We would expect to see a parabola shaped line as shown in Figure 6 and Figure 1. As previously mentioned if we were to use Figure 5 for analysis we would get false predictive resul... | https://en.wikipedia.org/wiki/Underfitting |
Burnham & Anderson state the following. : 32 … an underfitted model would ignore some important replicable (i.e., conceptually replicable in most other samples) structure in the data and thus fail to identify effects that were actually supported by the data. In this case, bias in the parameter estimators is often subst... | https://en.wikipedia.org/wiki/Underfitting |
There are multiple ways to deal with underfitting: Increase the complexity of the model: If the model is too simple, it may be necessary to increase its complexity by adding more features, increasing the number of parameters, or using a more flexible model. However, this should be done carefully to avoid overfitting. U... | https://en.wikipedia.org/wiki/Underfitting |
Increase the amount of training data: If the model is underfitting due to lack of data, increasing the amount of training data may help. This will allow the model to better capture the underlying patterns in the data.
