woodturners-branding-iron-neural-network Project: Deep Learning Neural Network based Algorithmic Trading Strategies. Authors: Andrés Arévalo.  This paper presents a high-frequency strategy based on Deep Neural Networks (DNNs). The DNN was trained on current time (hour and minute), and \(n \)-lagged one-minute pseudo-returns, price standard deviations and trend indicators in order to forecast the next one-minute average price. The DNN predictions are used to build a high-frequency trading strategy that buys (sells) when the next predicted average price is above (below) the last closing price.

To build your neural network, you will be implementing several Woodturners Branding Iron Zone “helper functions”. These helper functions will be used in the next assignment to build a two-layer neural network and an L-layer neural network. Each small helper function you will implement will have detailed instructions that will walk you through the necessary steps. Here is an outline of this assignment, you will: Initialize the parameters for a two-layer network and for an L-layer neural network.  The initialization for a deeper L-layer neural network is more complicated because there are many more weight matrices and bias vectors. When completing the initialize_parameters_deep, you should make sure that your dimensions match between each layer. Recall that $n^{[l]}$ is the number of units in layer $l$.

Most palm-sized PDAs have four-inch 10 cm square screens which are used for both Woodturners Branding Iron Effect output and input. The screen displays information with an LCD. On top of the LCD sits a touch screen that lets the user launch programs by tapping on the screen with a pen-like stylus or enter data by writing on it.

In order to use a PDA for brand recognition, using a plastic stylus, the brand inspector first draws a brand on the device's touch screen. Next, software inside the PDA matches the drawing to the letters, numbers, and symbols of listed brands. To help the software make more accurate matches, the brand inspector can use an onscreen keyboard, and tap on the letters or numbers with the stylus. Some PDAs now have a built-in digital camera that can be used to capture an image of the brand directly off the animal.

Software can be used to extract the brand from the image, which is then processed similar to the processing of the touch screen drawing, previously described. The brand inspector can assist in the process by cropping the image and tracing the brand.

Various sensors can be connected to a PDA which enable data to be input into it. The PDA can thus not only store the image into the data bank of known brands, but also retrieve the most closely matching brand or brands.

Colored indicia can also be affixed to the livestock. Although numerous ways of affixing colored indicia can be used and will produce desirable results, it is preferred that a colored tattoo or a branding iron treated with a colored die be used to affix the colored indicia. A color sensing sensor can then be attached to a PDA and used to scan the indicia into the PDA not only for data entry purposes but also for brand identification purposes.

Advanced PDAs incorporate voice recognition technology. This enables the brand inspector to read the brand while speaking into a built-in microphone. Software converts the voice sound waves into letter, number and symbol data that can be matched against listed brands. The PDA can be programmed with other specific sounds which are then equated with a specific brand.

The central focus is to identify some form of automated or semi-automated character recognition software that can be easily implemented on a PDA. There are numerous algorithms that perform this task. These fall into two basic categories: feature extraction methods that use artificial intelligence techniques for classification, and neural network approaches that require virtually no preprocessing.

The proposed approach to the area of pattern recognition preferably uses a PDA to implement the pattern recognition algorithms, as also shown in FIG.

Any character image is captured preferably by the touch screen or camera and then image digitization is performed. The process of digitization vertically and horizontally partitions the image pixels, and assigns a value to each pixel.

The value assigned to a pixel of a monochrome image varies according to its brightness or gray level. The image digitization is preferably accomplished manually by overlaying a grid over the handwritten character images. In feature extraction methods, the digitized image is preferably further processed using image processing techniques in order to perform the recognition task. The general idea of the feature extraction is to identify characters based on features that are somewhat similar to the features humans use to identify characters.

The rationale is that when the algorithm does misclassify a character, as any algorithm occasionally may, it should pick a character that a human would consider to be a reasonable guess. This is because it is easier for humans to correct mistakes that are typical of humans i. Feature extraction methods have achieved better than a However, the feature extraction method of pattern recognition is a computationally intensive and time consuming task due to the vast amount of image data and large number of computation steps.

Using the conventional approach typically demands a very high-speed computer or a parallel computer system to perform a satisfactory recognition. Character recognition for brands pose new and interesting pattern recognition problems when compared to recognition of the 68 English character set. The size of the corpus is daunting, in that there are brands contain tens of thousands of characters, including a few hundred symbols.

However, since most brands contain either a letter or a number, an alphabetical listing can be used to reduce the candidate character set to hundreds.

From a pattern recognition standpoint, brands are of widely varying complexity, consisting of a few to tens of distinct strokes. Differences between brands can be quite small. In contrast, the differences between handwriting styles can Woodturners Branding Iron 25 be significant. Both of these factors together are a potential problem for feature extraction methods of writer-independent recognition techniques. Specifically, for a given feature, two brands may have only a small between-class variance and a large within-class variance, implying an overlapping of their distributions.

An embodiment of the present invention was constructed and measurements taken. In this experiment, the focus was to develop a method for character recognition easily implemented on a PDA both in terms of memory and processing speed. The neural net approach utilized three separate steps. The first step simply translated the binary character data into a friendlier form. The second step took the output of the first and trained a backpropagation network on it, thus creating the weights and general network information.

The third step took the output of the second and created a network. The network consisted of 51 inputs, 4 outputs. It was essentially a flat feedforward network that was fully connected without self-inputs or biases. A pixel was taken to be zero if the pixel was empty, otherwise the pixel was interpreted as a one.

The pixel array was then converted into a set of 51 binary words of 5 bits each one pixel discarded. The four sets of 51 values were used to train the neural network. Each of the four outputs corresponded to one of the four characters in the training set. By applying a threshold of 0. The network was made to learn properly by using a step size of 1.

It converged fairly quickly and only required one-hundred thirty-nine sweeps through the training data set. The resulting C code is compact, and easily implemented on a PDA. The purpose of testing images of the same brand was to create an evaluator distribution biased toward images with high variance. Table 1 summarizes the results. Overall, the results of the neural net approach are promising. Even though the neural network does not do as good of a job as making typical human guesses, the network achieved a reasonable recognition rate approximately 3 out of four brand images correctly identified much faster than the feature extraction method can.

This is primarily due to the fact that while the feature extraction method has to use a dictionary and do a character by character comparison for each symbol to be identified at runtime, the neural network learned everything it needed to know about the training data set during its training phase and could get results for an input character with a single feedforward pass.

Based on the results of this example, it appears that the best method combines a neural network with simple feature extraction. The letter or number of a brand or none, in the case of a symbol would be provided by the human brand inspector prior to drawing or otherwise capturing the brand image. It is relatively easy create thirty or so neural networks trained on reduced data sets of a few hundred brands. Then, instead of an exact match, the neural network need only provide a half dozen or so nearest matches from which the brand inspector may choose.

Further, such a combined approach would maintain the desirable aspect of the feature extraction method of generally making human-like mistakes while utilizing the neural net method's identification speed and efficient use of memory. The hybrid approach to character recognition makes many other options possible. As such the hybrid approach likely provides the greatest opportunity for advancement.

The preceding example can be repeated with similar success by substituting the generically or specifically described operating conditions of this invention for those used in the preceding example. Although the invention has been described in detail with particular reference to these preferred embodiments, other embodiments can achieve the same results.
