What are the induction contradictions?Inductive paradox was an important concept in mathematics and logic. It referred to situations that could lead to errors or contradictions when drawing conclusions based on certain premises. The following are some of the most common induction contradictions:
1. The universal theorem: Assuming that all animals can fly, then one bird must be able to fly, two birds must be able to fly, and so on, all animals can fly.
The necessary condition contradiction: Assuming that all animals can fly, then a bird must be able to fly, but if this bird can't fly, then other animals can't fly either. Therefore, it was concluded that it was necessary for all animals to be able to fly.
3. Paragon of sufficient conditions: Assuming that all animals can fly, then a bird must be able to fly. If this bird can fly, then other animals can also fly. Therefore, it was concluded that it was a sufficient condition for all animals to be able to fly.
4. Bayes 'Paragon: Assuming that the probability of A is p, then if the probability of A is 1-p, then the probability of B is p. However, if the probability of A is p, then the probability of B is not p. Therefore, it is concluded that when the probability of a certain event A is p, the probability of B must be less than p.
These contradictions showed that there could be mistakes or contradictions in the conclusion of some premises in the process of induction. Therefore, in the process of induction and reasoning, it was necessary to carefully verify and select the premise to avoid producing a contradiction.
Plain Shu Nv WenI recommend a few ancient romance novels. " A Family of Common People ". The author accepted red packets. The male and female protagonists were both born of concubines and had no golden fingers. It was a history of the struggle of concubines. In the later stages, they lived a happy life. The male protagonist did not take concubines. There was no big flaw in the text. The female protagonist did not have the skills to kill all sides. The book was scarce. " A Peasant Woman's Leisurely Life " was written by Shui Mo Yunhua. The female protagonist had transmigrated into a village woman and lived a bitter life in the countryside. She had no special abilities and kept a low profile as she slowly brought her family out of nothing. " Di Daughter Zheng Wife ", written by I Love Su San. Modern women are reborn in ancient times. The female protagonist is not white and not omnipotent. The content is farming and family gossip. " Leisurely Daily Life in Ancient Times " was written by Rice Rice. It was the warm daily life of a post-apocalyptic woman traveling through ancient times and a farmer boy. There was no scheming. " Family " was a melodramatic work. The female protagonist was forced to marry her sister in a flash. There was no palace and house fights, only a simple life.
The main content of the mathematical storyMathematics stories usually involve an interesting mathematical problem or topic and unfold the story by telling the life of a mathematician or someone related to mathematics. The story would usually tell the mathematicians 'discoveries, challenges, successes, and failures, and how they applied these discoveries to practical problems or solved other difficult problems.
A typical mathematical story might involve the following topics:
- Exploring the unknown: mathematicians may challenge their own unknown areas to advance mathematics by solving difficult problems.
- Discovering new theories: A mathematician may discover new theories or laws that may have an impact on existing mathematical theories.
- Mathematics: mathematicians may apply mathematics to practical problems to solve various problems and advance science.
- The beauty of mathematics: mathematicians may explore the beauty and meaning of mathematics and how to apply it to human life and other fields.
Mathematics stories are often an interesting way to explore the mysteries and meaning of mathematics by telling the stories of mathematicians.
Artificial intelligence mathematical modelArtificial intelligence mathematical models were the foundation of artificial intelligence technology. The following are a few key mathematical theories involved in building the mathematical model of artificial intelligence:
** 1. Liner Algebra **
1. ** abstract and formalized **
- It provided a way to abstract specific things into mathematical objects, such as formalizing the research object into a matrix or a matrix. In artificial intelligence, many data and operations could be expressed in terms of matrices. For example, in image processing, an image could be seen as a matrix of the elements, and operations such as transformation and compression of the image could be achieved through matrix operations.
- Vectors can be regarded as stationary points in n-dimensional linear space, and linear transformations (which can be expressed in matrices) describe the changes in a coordinate system. The matrix's characteristic values and characteristic matrices could describe the speed and direction of change, which was very important for understanding the law of change in the data in the model.
2. ** Big Data and Machine Learning **
- Matrix operations in linear algebra were widely used in big data processing and machine learning. For example, in neural networks, input data, weights, and so on were in the form of matrices. The forward and backward transmission of data was achieved through operations such as matrix multiplication, so as to train and predict the model.
** 2. Theory of probability and mathematical statistics **
1. ** Theory of probability **
- The theory of probability was a way of looking at the possibilities that existed everywhere in the world, and it was indispensable in the study of artificial intelligence. With the rise of the Connectionist School, probability statistics became the mainstream tool for artificial intelligence research.
- The frequency school and the Bayes school had different views. For example, the frequency school believed that the prior distribution was fixed and calculated the model parameters by the maximum likelihood estimation. The Bayes school believed that the prior distribution was random and calculated the model parameters by the maximum probability. The normal distribution was the most important random variable distribution.
2. ** Mathematical statistics **
- Mathematical statistics was based on probability theory, but the research methods were different. It studied random phenomena based on observed or experimental data, and made reasonable estimates and judgments on the objective laws of the research object.
- Their tasks included inferring the general properties of the sample, using tools such as statistics (the function of the sample, which was a random variable). The unknown parameters of the population distribution (point estimation and interval estimation) are estimated by the sample. The hypothesis test accepts or rejects a judgment about the population by the sample. It is often used to estimate the generalisation error rate of the machine learning model.
** 3. Theory of optimization **
1. ** Target and Essence **
- The goal of artificial intelligence was optimization, which was to make the best decision in complex environments and multi-body interactions. Almost all artificial intelligence problems ultimately boiled down to solving optimization problems.
2. ** Solution process **
- The theory of optimization was to determine whether the maximum (minimum) value of a given objective function existed and to find the value that made the objective function reach the maximum. For example, in model training, the objective function was treated as a mountain range, and the optimization process was to determine the location of the peak (the minimum value) and find the path to the peak. In the linear search, the first and second derivative of the objective function were needed to determine the search direction; the confidence region algorithm first determined the search step size and then determined the search direction; the artificial neural network and other evolutionary algorithms were important optimization methods.
** 4. Information Theory **
- Information theory studied the transmission, storage, and processing of information. It provided the theoretical basis for data compression and signal processing of artificial intelligence, and also provided support for the learning methods of models.
** 5. Other mathematical theories **
1. ** Graph Theory **
- Graph theory was a branch of mathematics that studied the study of scattered structures and objects. It was mainly used in search algorithms, decision trees, and other aspects to provide the basis for reasoning and decision-making in intelligent systems.
2. ** Dispersed Mathematics **
- It played a key role in algorithm design, natural language processing, and other aspects. It was one of the foundations of the entire computer science.
3. ** Mathematical logic **
- Research on reasoning and proof was widely used in reasoning engines and intelligent search, providing the basis for reasoning and decision-making in intelligent systems.
4. ** Complex Theory **
- He studied the complexity of computational problems and provided a scientific basis for evaluating the efficiency of artificial intelligence by analyzing the time complexity and space complexity of the algorithm.
5. ** Group Theory **
- A branch of mathematics that studies the structure of algebra and symmetries. It is widely used in image processing, pattern recognition, and encryption to help understand and analyze complex data structures and patterns.
