He mentors aspiring data scientists through Thinkful, and maintains a Data Science / AI blog. Instead of running your code from the command line by calling ‘julia my_code.jl’, you can first start the REPL by just calling ‘julia’ and then load your code by calling ‘include(“my_code.jl”). The training and validation accuracy scores are almost the same which helps to alleviate any concerns about overfitting/underfitting. It’s a more optimized implementation with very smart tweaks!

Accuracy as a metric will suffice since the focus is more on the implementation than anything. While it has an interesting language design and shows potential in many areas, the limited machine learning ecosystem and community needs to grow and mature before it can compete with Python. I plan on making more experiments unpacking both classic and contemporary algorithms with this interesting programming language in future posts.

The Julia Series, by Dr. Zacharias Voulgaris, Unleash the power of Julia for your machine learning tasks. Furthermore, Julia has made the following design decisions: Altogether, these features are supposed to make Julia more expressive, enable overloading, increase the range of possible use cases, and simplify debugging. Hands-on real-world examples, research, tutorials, and cutting-edge techniques delivered Monday to Thursday. So you will not build anything during the course of this project. Flux is a machine learning library which “lets you use the full power of the Julia language where you need it.” When compared to the two most popular ML frameworks in Python, working with Flux feels more like working with PyTorch than TensorFlow due to its syntax. The first few chapters are the 101 of Julia, but then the book turns and goes deeper and deeper into Data Science. Consequently, we will attempt to build from scratch the most famous classification algorithm, logistic regression (with regularization) in Julia! Statistics with Julia: Fundamentals for Data Science, Machine Learning and Artificial Intelligence .
Just like compilation time, training the VAE seemed rather slow in Julia compared to Python, as our comparison below shows. Quantitative Analysis for System Applications, Data Science Mindset, Methodologies, and Misconceptions, Zack wrote the Julia entry for SpringerLink. Additionally, our tests uncovered that the Flux.jl library seems to have an excessive memory consumption that is significantly higher than Pytorch’s. The results are interestingly close but it’s unsurprising that sklearn’s implementation edges it in terms of the accuracy scores. Furthermore, the documentation and examples were often lacking or outdated. So, although Julia is supposed to be faster than Python, issues like this one hamper its speed significantly, making it frustrating for developers. This makes straying from the “common path” somewhat difficult in Julia, requiring more intimate knowledge of the respective libraries. See the original article here.
As I longtime Python developer, I appreciated the conciseness and the speed of Julia and the variety of libraries available for Data Science. However, it is not as mature as either one of those as it lacked flexibility in building custom models and components.
Can Julia Rival Python for King of Data Science? Additionally, "Julia was selected by the Climate Modeling Alliance as the sole implementation language for their next generation global climate model. This post builds on the first post where we built multivariate linear regression from scratch using our new found love, Julia! For many reasons, it is praised to be the “King of Data Science”. Let’s check if that’s the case with this experiment: The plot shows a reduction in cost values as the number of iteration increases which is a positive sign that the implementation is working!
Compared to Python, you cannot build complex workflows as easily. Obviously, it is aiming high — reason enough for us (Daniel and me) to have a closer look and test it in the scope of Motius Discovery. Compared to equivalent Python libraries like TensorFlow Datasets, MLDatasets is rather limited as it is missing e.g. With the features now normalized, let’s define “hypothesis” and “cost functions” for our regularized logistic regression : The goal here is to find the weights (θ) that minimizes the regularised cost function defined above using the gradients for direction. In constructing the VAE in Julia, we tried three different libraries, namely Flux, MLDatasets, and Augmentor. When it comes to data science, developers need a flexible and versatile language that is simple to code but still able to handle complex mathematical processes. Let’s make some predictions and test for the accuracy of the generated regularised model. In this post, we have successfully implemented from scratch regularised logistic regression using gradient descent in Julia. For readers already familiar with the topic, let’s jump straight into the implementation code.
Some scavengers are feeding off the “AI hype” with those half-baked “learn data science in 30 days” schemes which often leads unprepared students with no real intuition behind their “fit and predict” templates.
Over the past couple of years, Python has constantly been among the world’s most popular programming languages with a community of more than eight million developers. The plan of attack for this experiment is just like a typical modelling workflow where the data will be: With the various partitions loaded, let’s turn our attention to the implementation stage. Now, let’s talk about our findings from our experiments. However, be careful using this workaround, as variables in the global scope are not removed when calling include multiple times. In fact, we experienced waiting times of up to five minutes just to pre-compile some imported libraries like Flux. It’s a good thing that we have moved past those times as most problems end up as an optimization problem. However, there is a workaround for this issue. Over a million developers have joined DZone.
