Statsmodels provides a wide range of statistical and econometric tools for data analysis. It is particularly useful for estimating and testing statistical models and includes functions for linear regression, generalized linear models, time series analysis, and other types of statistical analysis. Statsmodels also includes a suite of diagnostic tools for checking the assumptions of statistical models and tools for model selection and evaluation. In addition, Statsmodels provides several visualization tools for creating publication-quality plots and graphs. JAX by Google allows users to easily and efficiently perform mathematical operations on arrays, including linear algebra and differentiation.

When it comes to coding, Python happens to be one of the most popular languages. It is true that there are alternatives, but Python has been steadily growing in terms of its usability. At the same time, it is important to note that while Python is popular, it still has some downsides, such as performance and a somewhat disorganized build system. Regardless, these cons can be overcome, and Python offers more than enough for its users, particularly if they are working on something related to machine learning. The purpose of this article is to cover some of the best Python libraries for machine learning.

This article was published as a part of the Data Science Blogathon. Social Media platforms are a common way to share interesting and informative images. Food images, especially related to different cuisines and cultures, are a topic that appears to be frequently trending. Social media platforms like Instagram have a large number of images belonging to different categories. We all might have used the search options on google images or Instagram to browse through yummy-looking cake images for ideas.

Today, we'll be going through the second and final part of the image classification tutorial! As a brief review of the last tutorial, we covered how to pass our dataset into a dataloader which we will be using today for the model learning and fine-tuning. Here's a recap of the last code used: This is what we've been waiting for! We want to create a model that is able to distinguish the different pet breeds in our dataset. I have to admit that it took me a while to fully understand this because there are just so many improvements you can make as you fit the model.

Fast.ai, San Francisco, CA 94117, USA Author to whom correspondence should be addressed. These authors contributed equally to this work. It aims to do both things without substantial compromises in ease of use, flexibility, or performance. This is possible thanks to a carefully layered architecture, which expresses common underlying patterns of many deep learning and data processing techniques in terms of decoupled abstractions. These abstractions can be expressed concisely and clearly by leveraging the dynamism of the underlying Python language and the flexibility of the PyTorch library. We used this library to successfully create a complete deep learning course, which we were able to write more quickly than using previous approaches, and the code was more clear.

Model training can be seen as the generation of subsequent versions of a model -- after each batch, the model weights are adjusted, and as a result, a new version of the model is created. Each new version will have varying levels of performance (as evaluated against a validation set). If everything goes well, training and validation loss will decrease with the number of training epochs. However, the best performing version of a model (here abbreviated as best model) is rarely the one obtained at the end of the training process. Take a typical overfitting case -- at first, both training and validation losses decrease as training progresses.

This is a copy of an article from my main newsletter: http://the.truthm.com/archive/921910 This is a writeup of a simple ML project I did this week. I'll walk through how I did it and the challenges I faced. Don't expect this to be wildly educational -- it's written more for my benefit than for anyone else's. After publication, I'm hoping to deploy this somewhere where you can put in various inputs and get a predicted genre (which, spoiler alert, probably won't be accurate).

I started using Pytorch and Fastai recently . Below I outline key concepts which will be helpful during image processing or in any computer vision problem . The first step will be to import all the necessary files. Fastai allows us to download the whole dataset in a just few lines of code. The above code will import all the necessary packages for our task and the last line will install the full MNIST dataset to our directory.

This blog post is part of the 100-days of Deep Learning challenge. I have started this challenge by reading the book "Deep Learning for Coders with fastai & PyTorch" by Jeremy Howard and Sylvain Gugger, to learn about the fastai library and its applications in deep learning. Fastai library is a deep learning library that adds higher-level functionalities on top of PyTorch. So this is a perfect choice of the library for quick prototyping and model building on different datasets as well as utilising the flexibility and speed of PyTorch. In this blog post, let us discuss the data-centric approach of training deep learning models.

Libraries like TensorFlow and PyTorch take care of most of the intricacies of building deep learning models that train and infer fast. Predictably, this leaves machine learning engineers spending most of their time on the next level up in abstraction, running hyperparameter search, validating performance, and versioning models and experiments to keep track of everything. If PyTorch and TensorFlow (and now JAX) are the deep learning cake, higher-level libraries are the icing. For years now TensorFlow has had its "icing on the cake" in the high-level Keras API, which became an official part of TensorFlow itself with the release of TF 2.0 in 2019. Similarly, PyTorch users have benefited from the high-level fastai library, which is exceptionally well-suited for efficiency and transfer learning.
