Essay about A Proposed ICA Algorithm
This algorithm performs adaptive optimization of kurtosis based contrast function in floating point arithmetic. The main aim of this algorithm development is to reduce the number of manipulations and to improve the performance of ICA algorithm in terms of convergence speed, area, frequency and power. The convergence speed of the algorithm is improved by focusing the search in particular directions rather than searching for the solution in a random manner. The random number generator unit present in FastICA has been replaced by an adaptive optimization unit .This adaptive optimization unit updates the weight values based on the kurtosis function. Since adaptive optimization unit contains a subtractor and …show more content…
This algorithm performs adaptive optimization of kurtosis based contrast function in floating point arithmetic. The main aim of this algorithm development is to reduce the number of manipulations and to improve the performance of ICA algorithm in terms of convergence speed, area, frequency and power. The convergence speed of the algorithm is improved by focusing the search in particular directions rather than searching for the solution in a random manner. The random number generator unit present in FastICA has been replaced by an adaptive optimization unit .This adaptive optimization unit updates the weight values based on the kurtosis function. Since adaptive optimization unit contains a subtractor and comparator, it involves lesser area and power when compared to random generator unit. In this algorithm, initial weight vectors for estimating the demixing matrix B in (2), are assumed as Wi’s. This algorithm computes new weights from the initial weights in adaptive manner based on absolute value of fitness function. Contrast function Iteration Unit
The efficiency of source estimation is based on the selection of cost functions, also called as objective functions or contrast functions. The Cost function is a measure of independence [4]. Some measures of independence are Kurtosis, mutual information and negentropy. Although different contrast functions exist, the most popular contrast function used in ICA is kurtosis. Central limit

Implementing The Proposed Algorithm, Local Implementation And Global Implementation
1362 Words  6 PagesThere are two options for implementing the proposed algorithm, local implementation and global implementation. Speed, circuit area, and power consumptions are main considerations when choosing the implementation options. For the prediction circuit, since the input pixel value varies column by column, the circuit should be implemented locally. Another reason for doing this is that the prediction circuit is fully digital and does not occupy too much silicon area. In the case of the judgement circuit…

Proposed Prediction Adc Algorithm : Prediction, Judgement, And Final Conversion
1561 Words  7 PagesThe proposed prediction ADC algorithm contains three key procedures: prediction, judgement, and final conversion. At the beginning, the prediction circuit generates common MSBs from a data memory that stores the digital results of the pixels in the previous row. Then the judgement circuit creates two analog boundary voltages based on the predicted MSB values and check whether the current pixel’s analog value is between the two boundary voltages based on Eq. (1). Finally, if the predicted MSB values…
