how to present a machine learning project

It’s helpful to know how well humans perform on the test set, or how well existing / competing systems perform. Check the examples the model gets wrong on the training set for labeling errors, missing fields, etc. The project entitled ‘Identifying Product Bundles from Sales Data’ is one of the interesting machine learning projects in R. To develop this project in R, you have to employ a clustering technique that is the subjective segmentation to find out the product bundles from sales data. The lack of customer behavior analysis may be one of the reasons you are lagging behind your competitors. We suggest putting code to do this at the end of every experiment to habituate yourself to looking at these numbers every time. Manually inspect some training examples at the stage of your code just before they are consumed by the training algorithm. At Insight for example, when AI Fellow Jack Kwok was building a segmentation system to help with disaster recovery, he noticed that while his segmentation model performed well on his training set of satellite imagery, it performed poorly on the development set, which contained cities that were flooded by hurricanes. For example, if you notice your tree detector consistently performs poorly on foggy images, play with OpenCV to add an augmentation step that makes your images look a bit foggy. This will save you hours/days of work. You will also need to become adept at iterating quickly. Profit increase, cost reduction, and customer satisfaction are some examples to follow to identify the return of investment on the machine learning initiative. Well-known companies such as Amazon, Google, Airbnb, Netflix, and Tesla are examples of full utilization of machine learning in their business. Another important step is to identify where to apply it in your business. Sequence the analyses? When you are just starting to scope out a new project, you should accurately define success criteria, which you will then translate to model metrics. We’ll talk about public dataset opportunities a bit later. In this case, now might be a good time to clean up any components you know are working well and make sure that the experiment can be reproduced by others in your team. For example, your eCommerce store sales are lower than expected. Present 97.0 97.0 . As Machine Learning (ML) is becoming an important part of every industry, the demand for Machine Learning Engineers (MLE) has grown dramatically. These give you a bound on the. For simplicity, we’ve elected to minimize “error rate” as our performance metric below. If your performance improved somewhat, you might be on the right track. This “dashboard” of often-used diagnostic outputs can help you overcome that moment of thinking “Ugh! Many research papers now have freely available code — so try to get code before reimplementing an idea from a paper as there are often undocumented details. On average, we will have: training error <= development set error <= test set error (if the data in each set follows the same distribution). Therefore, they must be used as a solid basis on which to make decisions. The world is still figuring out how to best run AI / machine learning projects. Jeromy Anglim gave a presentation at the Melbourne R Users group in 2010 on the state of project layout for R. The video is a bit shaky but provides a good discussion on the topic. Feel free to get in touch. While there are fun applications of machine learning as well, choosing problems of real import will have a higher chance of getting noticed on your professional portfolio. In this article, we will let you know some interesting machine learning projects in python with code in Github. As Machine Learning (ML) is becoming an important part of every industry, the demand for Machine Learning Engineers (MLE) has grown dramatically. Aim to make the test and development sets large enough that your performance metric will be accurate enough to make good distinctions between models. We recommend these ten machine learning projects for professionals beginning their career in machine learning as they are a perfect blend of various types of challenges one may come across when working as a machine learning engineer or data scientist. In this section, we have listed the top machine learning projects for freshers/beginners, if you have already worked on basic machine learning projects, please jump to the next section: intermediate machine learning projects. For example, if we are recommending 5 articles to individual users on a news platform, how many of them do we need to be relevant, and how will we define relevance? If your test metric (as optimized by your ML code) is diverging from your business metric, the end of this measurement cycle is a good time to stop and consider changing your optimization criterion or test set. If possible, for any problem, we recommend going through these successive steps: Write tests to check whether your gradients, tensor values, and input data and labels are properly formatted. In general, I have answered that is not necessary because it is possible to find specific needs like customer clustering or product recommendation, using your existing data exported from your CRM system, you can create a very effective model, able to give you a quick return on your investment. Today it is possible to do it with just a few clicks and is almost totally free. Reaching parity with human test performance is often a good long-term goal for many tasks. The goal is to take out-of-the-box models and apply them to different datasets. A machine learning project should not be based on data that does not provide information or that is not of quality, because it will be a waste of time. Divide a project into files and folders? While those opportunities exist, usually the real value comes from internally collected golden data nuggets mined from the business decisions and activities of your own company. In an effort to further refine our internal models, this post will present an overview of Aurélien Géron's Machine Learning Project Checklist, as seen in his bestselling book, "Hands-On Machine Learning with Scikit-Learn & TensorFlow." The model may be too small or inexpressive. They assume a solution to a problem, define a scope of work, and plan the development. Using the training, development and test error rates from your last experiment, you can quickly see which of these factors is currently a binding constraint. For example, if you are using linear regression for a problem that is highly nonlinear, your model is simply incapable of fitting the data well. 6. Slowly tweak the implementation of the model and the data pipeline to match your needs. For example, when there is a small gap between training error and development set error then your training error represents the bottleneck to improved performance. Most people overestimate the cost associated with gathering and labeling data, and underestimate the hardship of solving problems in a data starved environment. MLEs combine machine learning skills with software engineering knowhow to find high-performing models for a given application and handle the implementation challenges that come up — from building out training infrastructure to preparing … This is one of the fastest ways to build practical intuition around machine learning. Changing the test set alters the team’s goal, so it is helpful to fix the test set early and modify it only to reflect changes in project, product or business goals. If an existing solution might work (e.g., using another optimization algorithm already implemented in your toolkit), start with that. Search over a wider or finer-grained range of hyper-parameters to ensure you find the model that performs best on the development set. For example, in customer service, many businesses start with customer clustering or next best action recommendation. Good implementation skills are important, and coding hygiene can prevent bugs. The development set is the team’s proxy for test performance that they can use to tune hyper-parameters. Now it’s time to start iterating! 1. We must keep in mind that machine learning algorithms abstract patterns from data, but they don't reason. Or talk to a systems expert about ways to make your training faster. Machine Learning Project 1. Convert default R output into publication quality tables, figures, and text? In any event, the ultimate goal is to bring test performance as close to our guess for optimal performance as possible. A different type of model can alter how well you fit your data and how well it generalizes, so it is difficult to know when this will work. Going back in time, as electricity did replacing vapor machines. MLEs can follow a similar framework to cope with uncertainty and deliver great products quickly. Further, diligently returning to error analysis with an open mind often reveals useful insights that will improve your decisions about what to do. This has transformed teams, and allowed countless Fellows to deliver on cutting-edge projects. Collecting data is a common way to get better performance. Arthur Samuel coined the term “Machine Learning” in 1959 and defined it as a “Field of study that gives computers the capability to learn without being explicitly programmed”.. And that was the beginning of Machine Learning! Build the final product? Every data scientist should spend 80% time for data pre-processing and 20% time to actually perform the analysis. Success for an ML team often means delivering a highly performing model within given constraints — for example, one that achieves high prediction accuracy, while subject to constraints on memory usage, inference time, and fairness. Similarly, tagging some as “very easy” might tip you off to a trivial mistake in your system that’s causing it to miss out on easy cases. To bootstrap the loop described below, you should start with a minimal implementation that has very little uncertainty involved. Once you have historical data as raw material, it is time to discover which business metrics will be used to measure the model’s effectiveness. Performance is defined by whichever metric is most relevant to the success of your end product, whether that be accuracy, speed, diversity of outputs, etc. Homesite problem: Predicting Quote conversion - Homesite sells Home-insurance to home buyers in United States - Insurance quotes are offered to customers based on several factors What Homesite knows - Customer’s geographical, personal, Financial Information & HomeOwnership details - Quote … Prediction, Forecasting, Classification, Categorization, Time Series, Video, Voice and Text recognition are some possible examples of how to apply ML to your business. If you’re using a traditional model (such as a decision tree or gaussian mixture model), switching model classes is much more involved. A mislabeled test set is about the same as an incorrectly specified product requirement. Common departments are marketing, customer services, sales, etc. 2019-10-23 by Grigory Starinkin & Oleg Tarasenko . On the other hand, if performance became worse or didn’t improve enough, you’ll need to decide whether to try again (going back to the analysis phase) or to abandon your current idea. In machine learning, there is an 80/20 rule. Some examples may be mislabeled or have multiple reasonable labels. 3. Most people overestimate the cost associated with gathering and labeling data, and underestimate the hardship of solving problems in a data starved environment. If you could get started with some simple heuristic features, go for it. This typically means: For instance, if we’re building a tree detector to survey tree populations in an area, we might use an off-the-shelf training set from a similar Kaggle competition, and a hand-collected set of photos from the target area for development and test sets. When in doubt, buying an upgraded GPU or running more experiments in parallel is a time-honored solution to the “hurry up and wait” problem of ML experimentation. Some examples may be more difficult than others, or may be missing context needed for a good decision. Learn more about the Artificial Intelligence program. After all, it is difficult to know how well a model will perform by the end of a given training run, let alone what performance could be achieved with extensive tuning or different modeling assumptions. Learners can then build classification models that will accurately predict future activities. That is our main focus when dedicating time to such projects. Do this as you are setting up your model initially, that way if you catch an error once, you will never have to deal with it again. We suggest that ML engineers and their teams enumerate as many ideas that might work, and then bias toward simple, fast solutions. Top Machine Learning Projects for Beginners. it could be that the search method isn’t finding good choices. Answer the questions on this checklist and share it with everyone. Labeling and cleaning data is a common task. This list of machine learning project ideas for students is suited for beginners, and those just starting out with Machine Learning or Data Science in general. Remember that the latter metrics are what matters in the end, since they are the ones determining the usefulness of what you are building. Given this performance criterion and the data you have, what would be the simplest model you could build? I really like the motivation questions from Jeromy’s presentation: 1. Add more training data. 5. You cannot expect a model trained exclusively on sharp images to generalize to blurry ones. In this article, we’ll describe our conception of the “OODA Loop” of ML: the ML Engineering Loop, where ML Engineers iteratively. Want to learn applied Artificial Intelligence from top professionals in Silicon Valley or New York? If you’re feeling stuck on diagnosing the bottleneck or selecting a good model to try next, consider reaching out to experts. So, basically, I enjoy doing such projects that give us a way to gain immense knowledge in a way and let us explore the unexplored dimensions. For numerical optimizers, try adjusting the learning rate or momentum settings. For example, when using decision trees you could make the trees deeper. The purpose of the ML Engineering Loop is to put a rote mental framework around the development process, simplifying the decision making process to focus exclusively on the most important next steps. Augment your data with novel samples generated from real training examples. If your analysis stage is slowing you down, create a script that summarizes the results of an experiment, collects errors from the training and dev sets, and formats them nicely. Don’t get bogged down trying to develop a complete understanding of every shortcoming — — aim instead to understand the biggest factors since many of the smaller issues will change or even disappear as you make improvements to your model. In practice, there might be many different overlapping issues responsible for the current results, but your objective is to find the most glaring issues first so that you can resolve them quickly. You’ll often end up building a “dashboard” with your test metric and business metrics as well as other useful data that you can see at the end of every experiment. This project is awesome for 3 … Adding an extra augmentation step to the training pipeline, that applied blurring to images helped reduce the gap between training and development performance. I invite you to attend my speech at ODSC this April where I will share my experience in machine learning projects and I will show you a proven method based on Design Sprint and Machine Learning Canvas to start to use immediately in your company, reducing risks, discovering bottlenecks and predicting your return on investment in a practical way, always focusing on to generating value for your business. A lot of people ask me if it is necessary to build a data lake or buy external information to start a machine learning project. That said, since a large fraction of ideas will fail, feel free to hack your experiment code with abandon and throw away failed code while you’re in the process of iterating. Subsequent sections will provide more detail. Once you feel comfortable that you’ve made useful progress, you can impose some discipline and clean up before the next loop. There are mountains of data for machine learning around and some companies (like Google) are ready to give it away. Now, how can this be done in a short time and how can you identify if your investment in a machine learning project is feasible? So check out all of these projects and when you are done with them, you can attempt even more projects on Kaggle and also take part in the active competitions. Try a different model class. Useful performance metrics include accuracy and loss for the ML side, and business value metrics (how often do we recommend the right article amongst our top 5?) One could then check the training set to see whether similar accents are well-represented, correctly labeled, and successfully fit by the training algorithm. You can checkout the summary of th… Room with white objects: A little noise 2. Many types of professionals face similar situations: software and business developers, startups looking for product-market fit, or pilots maneuvering with limited information. Deep Learning has been the most revolutionary branch of machine learning in recent years due to its amazing results. Profit increase, cost reduction, and customer satisfaction are some examples to follow to identify the return of investment on the machine learning initiative. We could then run logistic regression on the raw pixels, or run a pre-trained network (like ResNet) on the training images. Filling out this checklist will give you one of the essentials of any successful machine learning project: understanding. Introduction to machine learning. Once you get in a rhythm, you can easily label. The hyper-parameters for the model are set poorly. This is especially useful when working in teams. While it’s hard to hold yourself accountable to hitting a specific accuracy goal when the fate of your experiment is uncertain, you can at least hold yourself accountable to finish that error analysis, draw up a list of ideas, code them, and see how it works. Divide code into functions? The most pressing reason for this challenge is that the process of developing new ML models is highly uncertain at the outset. Try a different form of regularization (such as weight decay, dropout for neural networks, or pruning for decision trees). Starting with a small momentum (0.5) is usually easiest to get working. Thus, you should also take time to think about improving the quality and speed of iteration so that you can make maximum progress during each cycle and you can finish many iterations quickly. How to build a machine learning project in Elixir. For a given diagnosis, there might be several potential solutions and the next step is to enumerate and prioritize them. The “inductive prior” encoded in your model is a poor match to the data. Another aspect is to identify if there is enough data to be the raw material to learn. This overview intends to serve as a project "checklist" for machine learning practitioners. The goal of this phase is to prototype rapidly so that you can measure the results, learn from them, and go back around the cycle quickly. It was something only in sci-fi a short time ago. We are living in an unpredictable moment in human history, being able to teach computers to “think” and to make decisions. Domain experts can often provide useful insights during error analysis (e.g., pointing out subtle distinctions that make some cases hard or easy), while research papers or experienced ML practitioners might have creative solutions to add to your list of things to try (and will be better able to help you if you can share your detailed analysis so far). If you have the choice between labeling 1000 data points or researching a cutting edge unsupervised learning method, we think you should collect and label the data. I have to run that analysis by hand again… I’ll just try this random solution instead.”, If you feel like you’re hand-wringing about what to try, just pick. One advantage of deep learning is that there is a wide range of “building block” neural network components you can easily try out. Leandro is a speaker for the ODSC East 2020 Virtual Conference. Several specialists oversee finding a solution. Leandro Lopes has helped companies like Roche, Ambev, Rabobank in Brazil and USA identify where and how to apply Machine Learning effectively by applying the L3 — Learn, Lean, Lead — Design Thinking and Machine Learning Canvas methodology. For any of the above situations, you can understand the failures of your models by manually inspecting a random set of examples your model gets wrong (You should generally not do this for the test set to avoid “training” your system on those examples.). Cartoonify Image with Machine Learning. I want to Add Concepts of Outlier. You can either fork these projects and make improvements to it or you can take inspiration to develop your own deep learning projects from scratch. These decisions are easier to make if each cycle of the ML Loop is relatively cheap: you haven’t put too much energy into making your code perfect, and another attempt won’t take too long — — so you can decide what to do based on the risk and value of the idea instead of sunk cost. Incorporate R analyses into a report? Find an implementation of a model solving a similar problem. Tagging some examples as “very hard” might help you direct your efforts to lower hanging fruit if several groups of errors are equally common. Bright light room: The projects presented many difficulties and worked with errors. The ML Engineering Loop above will help you make methodical progress toward a better model despite the inherent uncertainty of the task. All of these ML Project Ideas are great options if you are just starting in Machine Learning or if you know the basics and need more practice. Collect Machine Learning, Deep Learning, DataScience Concepts or Algorithm if the information is taken form any reference don’t forget to add a reference. As soon as you are convinced that machine learning is not a buzzword anymore, you may ask me: How can I start a successful project in my company to take advantage of all this potential without wasting money, focused on generating more value for my business? We say that the model is, The model may be too large or expressive, or insufficiently regularized. If the training dataset is too small, gathering more training data might be a reasonably quick and easy solution. Try different initialization strategies, or start from a pre-trained model. If your experiments are taking too long, consider spending some time looking for optimizations to your code. Machine Learning Gladiator. A good way to ensure this is to first curate a large pool of samples, then shuffle and split them into development and test sets afterward. The optimization algorithm (e.g., gradient descent for a deep neural network) is not precisely tuned. We say that the model has. That way anybody can easily jump in, give hints, and check the progress. After your analysis, you will have a good sense of what kind of errors your model is making and what factors are holding back performance. Which areas will be the best to apply machine learning models? Look at the. As with other decisions, only work on these items if they’ll address a current pain point. Therefore. He is director of innovation at L3, speaker, and researcher on the impact of artificial intelligence on human relations. It is the most important step that helps in building machine learning models more accurately.
