An auto encoder is an artificial neural network used for learning efficient codings. The aim of an auto encoder is to learn a compressed representation encoding for a set of data. This means it is being used for dimensionality reduction . More specifically, it is a feature extraction method. Auto encoders use three or more layers An input layer. For example, in a face recognition task, the neurons in the input layer could map to pixels in the photograph. A number of considerably smaller hidden layers, which will form the encoding. An output layer, where each neuron has the same meaning as in the input layer. If linear neurons are used, or only a single sigmoid hidden layer, then the optimal solution to an auto encoder is strongly related to principal components analysis PCA ref Auto association by multilayer perceptrons and singular value decomposition, H. Bourlard and Y. Kamp Biological, Cybernetics Volume 59, Numbers 4 5, 291 294, DOI 10.1007 BF00332918 ref . Training An auto encoder is often trained using one of the many backpropagation variants conjugate gradient method , steepest descent , etc. Though often reasonably effective, there are fundamental problems with using backpropagation to train networks with many hidden layers. Once the errors get backpropagated to the first few layers, they are minuscule, and quite ineffectual. This causes the network to almost always learn to reconstruct the average of all the training data. Though more advanced backpropagation methods such as the conjugate gradient method help with this to some degree, it still results in very slow learning and poor solutions. This problem is remedied by using initial weights that approximate the final solution. The process to find these initial weights is often called pretraining. A pretraining technique developed by Geoffrey Hinton for training many layered deep auto encoders involves treating each neighboring set of two layers like a Boltzmann machine Restricted Boltzmann machine restricted ... more details

Unreferenced date December 2009 A bitstream format is the format of the data found in some Stream computing stream of bits used in a digital communication or Data storage device data storage application.

Differential pulse code modulation DPCM is a signal encoder that uses the baseline of pulse code modulation PCM but adds some functionalities based on the prediction of the samples of the signal. The input can be an analog signal or a digital signal . If the input is a continuous time analog signal, it needs to be sampling signal processing sampled first so that a discrete time signal is the input to the DPCM encoder. Option 1 take the values of two consecutive samples if they are analog samples, quantization signal processing quantize them calculate the difference between the first one and the next the output is the difference, and it can be further entropy coding entropy coded . Option 2 instead of taking a difference relative to a previous input sample, take the difference relative to the output of a local model of the decoder process in this option, the difference can be quantized, which allows a good way to incorporate a controlled loss in the encoding. Applying one of these two processes, short term redundancy positive correlation of nearby values of the signal is eliminated compression ratios on the order of 2 to 4 can be achieved if differences are subsequently entropy coded, because the entropy of the difference signal is much smaller than that of the original discrete signal treated as independent samples. DPCM was invented by C. Chapin Cutler at Bell Labs in 1950 his patent includes both methods. ref U.S. patent 2605361, C.

The black section at the bottom contains the Epicyclic gearing planetary Reduction drive reduction gear , and the black object on top of the motor is the optical rotary encoder for position feedback. This is the steering actuator of a large robot vehicle. A servomotor is a motor which forms part of a servomechanism . The servomotor is paired with some type of encoder to provide position speed feedback. This feedback loop is used to provide precise control of the mechanical degree of freedom driven by the motor. A servomechanism may or may not use a servomotor. For example, a household furnace controlled by a thermostat is a servomechanism, because of the feedback and resulting error signal, yet there is no motor being controlled directly by the servomechanism. Servomotors are not the only means of providing precise control of motor output. A common alternative is a stepper motor . In a stepper motor, the input command specifies the desired angle of rotation, and the controller provides the corresponding sequence of commutations without the use of any feedback about the position of the system being driven.

News release date February 2008 Unreferenced date February 2008 The hybrid H ternary line code operates on a hybrid principle that combines the binary non return to zero level NRZ L and the polar return to zero RZ codes and thus it is called H ternary. The H ternary code has three levels for signal representation these are positive , zero 0 , and negative . These three levels are represented by three states. The state of the line code could be in any one of these three states. A transition takes place to the next state as a result of a binary input 1 or 0 and the encoder s present output state. The encoding procedure is as follows Glass and Bastaki 2001, Glass et al. 2001 . class wikitable style text align center Input bit Prior output Output level rowspan 3 0 rowspan 2 0 rowspan 2 0 rowspan 3 1 0 rowspan 2 In general, the encoder outputs level for a binary 1 input and a level for a binary 0 input. However, if this would result in the same output level as the previous bit time, a 0 level is output instead. Initially, the encoder output present state is assumed at 0 level when the first bit arrives at the encoder input. The new line coding scheme violates the encoding rule of NRZ L when a sequence of 1s or 0s arrives and hence, it overcomes some of their deficiencies. During the violation period for a run of 1s or 0s, it operates on the same encoding rule of the polar RZ but with pulse occupancy of full period. It is evident that NRZ L and polar RZ codes have deficiencies compared to the proposed H ternary encoding scheme. NRZ L code lacks sufficient timing information when the binary signal remains at one level in of either 1 or 0. This has direct influence on synchronising the receiver clock with that of the transmitter and, as a result, has impact on the detection of the received digital signal. The H ternary code has also timing superiority compared to similar ternary codes. Other ternary line code such as alternate mark inversion AMI also lacks the timing inform ... more details
In video compression algorithms a residual frame is formed by subtracting the reference frame video reference frame from the desired Video frame frame . This difference is known as the error or residual Video frame Video frames frame . The residual frame normally has less information entropy , due to nearby video frames having similarities, and therefore requires fewer bit s to compress. An encoder will use various algorithms such as motion compensation motion estimation to construct a frame that describes the differences. This allows a decoder to use the reference frame plus the differences to construct the desired frame. See also Motion compensation Category Video compression ... more details
