Star Code Issues Pull requests.In this paper we introduce a new, high-quality, dataset of images containing fruits. We also present the results of some numerical experiment for training a neural network to detect fruits.
We discuss the reason why we chose to use fruits in this project by proposing a few applications that could use such classifier. Mihai Oltean. The aim of this paper is to propose a new dataset of images containing popular fruits. Currently as of The reader is encouraged to access the latest version of the dataset from the above indicated addresses. Having a high-quality dataset is essential for obtaining a good classifier.
Most of the existing datasets with images see for instance the popular CIFAR dataset [ cifar ] contain both the object and the noisy background. This could lead to cases where changing the background will lead to the incorrect classification of the object.
As a second objective we have trained a deep neural network that is capable of identifying fruits from images.
This is part of a more complex project that has the target of obtaining a classifier that can identify a much wider array of objects from images. This fits the current trend of companies working in the augmented reality field. First step in creating such application is to correctly identify the objects. The software has been released later in as a feature of Google Assistant and Google Photos apps. Such a network would have numerous applications across multiple domains like autonomous navigation, modeling objects, controlling processes or human-robot interactions.
The area we are most interested in is creating an autonomous robot that can perform more complex tasks than a regular industrial robot.
An example of this is a robot that can perform inspections on the aisles of stores in order to identify out of place items or understocked shelves. Furthermore, this robot could be enhanced to be able to interact with the products so that it can solve the problems on its own.
As the start of this project we chose the task of identifying fruits for several reasons. On one side, fruits have certain categories that are hard to differentiate, like the citrus genus, that contains oranges and grapefruits.
Thus we want to see how well can an artificial intelligence complete the task of classifying them. Another reason is that fruits are very often found in stores, so they serve as a good starting point for the previously mentioned project.Artificial intelligence has created opportunities across many major industriesand agriculture is no exception.
Applying machine learning technologies to traditional agricultural systems can lead to faster, more accurate decision making for farmers and policy makers alike.

Life sciences and medical datasets are useful for providing economical solutions for healthcare and medical diagnosis software systems.F ew days ago I found a very interesting dataset in the Kaggle website. I do not know if you all know what Kaggle is all about but, apart from containing machine learning competitions, it provides very interesting datasets that users freely upload to the website. The point is that I saw an interesting dataset about the London Crime Data between and and I have analyzed it.
Thanks to Sohier Dane we have 3 excellent data sets with a snapshot of crime from London to mid Later I will try to find out its meaning. We can get very interesting conclusions about the city of London such as more dangerous areas, more common crimes, dates of more delinquency … etc. All the code of this analysis is inside this notebook so you can see all the code and reuse it if you want to. London Outcomes. This will be the first dataset to analyze.
This csv file contains the results of a crime investigation. This dataset contains the next columns:. In the United Kingdom, the Office for National Statistics maintains a series of codes to represent a wide range of geographical areas of the UK, for use in tabulating census and other statistical data.
We can see that the dataset has NaN values min rows if we want to be more especific. So we ere gonna clean these dataset to delete some noise using dropna method. We can see that the outcomes reports are between and which is very current data. It is logical that the resolutions are reported by the police.
How many of different outcome types are? We have cleaned our data set and we have explored the data a little superficially.
So the next step to take is plotting. Number of outcomes per month. The only pattern that I can see is that, as the months have gone by, the number of outcomes have risen. Although in the year the number of outcomes have varied sharply every month. Number of outcomes per type of outcome.
We can see And finally here ends the analysis of the first crime data set in London. In the following blog I will analyze the london-stop-and-search. If you see that there is something that can be improved, do not hesitate to share your ideas with me. My intention with this blog is to share my knowledge and learn new things.

About Help Legal.Kaggle, a popular platform for data science competitionscan be intimidating for beginners to get into. In this guide, we'll break down everything you need to know about getting started, improving your skills, and enjoying your time on Kaggle. Despite the differences between Kaggle and typical data science, Kaggle can still be a great learning tool for beginners. First, we recommend picking one programming language and sticking with it.
Fruit recognition from images using deep learning
If you go the route of Python, then we recommend the Seaborn library, which was designed specifically for this purpose.
It has high-level functions for plotting many of the most common and useful charts. Before jumping into Kaggle, we recommend training a model on an easier, more manageable dataset. The key is to start developing good habits, such as splitting your dataset into separate training and testing sets, cross-validating to avoid overfitting, and using proper performance metrics.
Now we're ready to try Kaggle competitions, which fall into several categories. The most common ones are:. With that foundation laid, it's time to progress to 'Featured' competitions.
In general, these will require much more time and effort to rank well. For that reason, we recommend picking your battles wisely.
Enter competitions that will expose you to techniques and technologies that align with your long-term goals. If you've ever played an addicting video game, you'll know the power of incremental goals. That's how great games get you hooked. Most Kaggle participants will never win a single competition, and that's completely fine.
If you set that as your very first milestone, you may feel discouraged and lose motivation after a few tries. On the other hand, you have plenty to gain, including advice and coaching from more experienced data scientists. In the beginning, we recommend working alone. This will force you to tackle every step of the applied machine learning process, including exploratory analysis, data cleaning, feature engineering, and model training.
With that said, teaming up in future competitions can be a great way to push your boundaries and learn from others. Remember, you're not necessarily committing to be a long-term Kaggler. If you find out that you dislike the format, then it's no big deal. Of course, competition anxiety is a real phenomenon, and it isn't limited to Kaggle. Once you feel comfortable, you can start using your "main account" to build your trophy case. Get instant access! Kaggle winner interviews.I followed a tutorial on Convolutional Neural Networks that left many questions unanswered.
Soon I realized that the actual process of architecting a Neural Network and setting the parameters seemed to be much more experimental than I thought.Picorv32 picosoc
It took a while to find explanations that a rookie like me could understand. If you wish to learn how a Convolutional Neural Network is used to classify images, this is a pretty good video. The ultimate guide to convolutional neural networks honors its name.
Keras provides an easy interface to create and train Neural Networks, hiding most of the tedious details and allowing you to focus on the NN structure. Keras allows you to go from idea to working NN in about 10 minutes. Which is impressive. The Keras workflow looks like this:. Keras provides a neat file-system-based helper for ingesting the training and testing datasets. Every subfolder inside the training-folder or validation-folder will be considered a target class. Remember that, even though we clearly see that this is an avocado, all the neural network may see is the result of some edge-detection filters.
So an avocado is this apparently green oval thing placed in the middle of the field. If you train the NN with perfectly-centered avocados and then feed it an off-center avocado, you might get a poor prediction.
In order to account for this and facilitate the training process, Keras provides the ImageGenerator class, which allows you to define configuration parameters for augmenting the data by applying random changes in brightness, rotation, zoom, and skewing.Imaging sonar
This is a way to artificially expand the data set and increase the robustness of the training data. One particularly important image augmentation step is to rescale the RGB values in the image to be within the [0,1] range, dividing each color value by This normalizes the differences in pixel ranges across all images, and contributes to creating a network that learns the most essential features of each fruit.
What is the configuration of the Neural Network? These were some of the questions that arose as I started to read tutorials, papers, and documentation. I watched a bunch of videos and this one provides the best explanation of what is a CNN and how it works:.
But the best way to understand how a CNN and each layer works at the most fundamental level is with these two examples:. Layers are the building blocks of Neural Networks, you can think of them as processing units that are stacked or… um… layered and connected. In the case of feed-forward networks, like CNNs, the layers are connected sequentially.
The process of creating layers with Keras is pretty straightforward. Just call keras. The two questions I found the hardest to answer were How many layers do I have to set up? These are often overlooked in tutorials because you are just following the decisions of someone else. The easy layers to figure out are the input and output layers. The input layer has one input node and in Keras there is not need to define it.
The output layer depends on the type of neural network. Now, for the hidden layers, we need to think about the structure of a Convolutional Neural Network. In general terms, Convolutional Neural Networks have two parts: a set of convolution layers and a set of fully connected layers.
The convolution layers produce feature maps mappings of activations of the different parts of an imagewhich are then pooled, flattened out and passed on to the fully connected layers. For the convolution layers, we need to strike a balance between performance and quality of the output.
I bet that there are cases with lower-quality images in which the extra convolutions will improve the performance of the network. The best explanation that I found for convolutional layers is to imagine a flashlight sliding over areas of an image and capturing the data 1s and 0s that is being made visible.
The flashlight is what we call a filter, the area that it is shining over is the receptive field and the way that the data is interpreted depends on weights and parameters. Each filter will have 1s and 0s arranged in a particular way, forming patterns that capture a particular feature, one filter will be pretty good at capturing straight lines, another one will be good at curves or checkered patterns.
The number of filters in the convolution is largely empirical.This page is about a ridiculous toy-data-set-gathering exercise that I engaged in. For this talk I wanted to show a data set and show a couple of algorithms running on it so that, hopefully, people could understand what was going on from start to finish. And gathering it myself forced me to think about some of the issues involved a bit more too. This is one of the plots I made:. I recorded the height, width and mass of a selection of oranges, lemons and apples.
I deliberately bought a few each of some different types to introduce some variety. I did not have ready access to calipers or any sophisticated equipment.
The masses were measured with some digital kitchen scales, which rounded to the nearest 2g. The lengths were measured by holding the fruit between two CDs compact discs and making marks on a sheet of paper! This probably introduced some systematic error and a fair amount of random error. I just tried to be fairly consistent in my procedure. We often have to deal with whatever poor-quality features are available. The heights were measured along the core of the fruit.Zed runes
The widths were the widest width perpendicular to the height. If you just want to look at some more pictures, see a subset of the slides from my talk showing just the oranges and lemons and a demo of K-means clustering. The clusters it finds roughly correspond to the different types of orange and lemon I bought.
These high variances oranges are scattered around the normal oranges, and one of them looks like a lemon…especially when coloured yellow.
The data are available in a tab-separated unix text file format. The columns correspond to fruit type, defined in this file. Several people have emailed me to ask if I have more of this data than provided here.
