Modeling Swing Probability

An aspect of baseball that has fascinated me for years is the mental game of chess that goes on between the batter and the pitcher during an at bat. Each player is constantly trying to get into the head of their opponent and guess what they might do next. The batter might be using his knowledge of the pitcher to predict whether he will try to challenge the hitter with a fastball or entice him to chase a breaking ball out of the zone. Meanwhile, the pitcher is employing information about the batter to formulate a sequence of pitches that should send him back to the bench with a strikeout.

It is in these mind games that I find statistics and sabermetrics can be applied most effectively. The more relevant data a pitcher or batter has, the larger their advantage is. In one of my previous articles, I quantified how well pitchers hide their pitches and discussed how batters could use this information to identify what a pitcher might be throwing (no trash cans necessary, Astros). However, in this article I want to investigate how pitchers can use information about the hitter to give themselves an edge. In particular, I will be trying to measure the probability that a certain batter will swing at a given pitch.

Workshop Alert! Deep Learning Model Deployment & Management

The Association of Data Scientists (AdaSci), the premier global professional body of data science and ML practitioners, has announced a hands-on workshop on deep learning model deployment on February 6, Saturday.

Over the last few years, the applications of deep learning models have increased exponentially, with use cases ranging from automated driving, fraud detection, healthcare, voice assistants, machine translation and text generation.

Typically, when data scientists start machine learning model development, they mostly focus on the algorithms to use, feature engineering process, and hyperparameters to make the model more accurate. However, model deployment is the most critical step in the machine learning pipeline. As a matter of fact, models can only be beneficial to a business if deployed and managed correctly. Model deployment or management is probably the most under discussed topic.

In this workshop, the attendees get to learn about ML lifecycle, from gathering data to the deployment of models. Researchers and data scientists can build a pipeline to log and deploy machine learning models. Alongside, they will be able to learn about the challenges associated with machine learning models in production and handling different toolkits to track and monitor these models once deployed.

Is Common Sense Common In NLP Models?

NLP Models have shown tremendous advancements in syntactic, semantic and linguistic knowledge for downstream tasks. However, that raises an interesting research question — is it possible for them to go beyond pattern recognition and apply common sense for word-sense disambiguation?

Thus, to identify if BERT, a large pre-trained NLP model developed by Google, can solve common sense tasks, researchers took a closer look. The researchers from Westlake University and Fudan University, in collaboration with Microsoft Research Asia, discovered how the model computes the structured, common sense knowledge for downstream NLP tasks.

According to the researchers, it has been a long-standing debate as to whether pre-trained language models can solve tasks leveraging only a few shallow clues and their common sense of knowledge. To figure that out, researchers used a CommonsenseQA dataset for BERT to solve multiple-choice problems.

Model Lifecycle: From ideas to value

In Part 1 of this series we examined the key differences between software and models; in Part 2 we explored the twelve traps of conflating models with software; and in Part 3 we looked at the evolution of models. In this article, we go through the model lifecycle, from the initial conception of the idea to build models to finally delivering the value from these models.

We breakdown the entire lifecycle of models into four major phases — scoping, discovery, delivery, and stewardship. While there are many similarities between this model lifecycle and a typical software lifecycle, there are significant differences as well, stemming from the differences between software and models that we started this series with. Here we go over the four phases and the nine steps within these phases.

How model queries work in Django

How model queries work in Django

Welcome to my blog, hey everyone in this article we are going to be working with queries in Django so for any web app that you build your going to want to write a query so you can retrieve information from your database so in this article I’ll be showing you all the different ways that you can write queries and it should cover about 90% of the cases that you’ll have when you’re writing your code the other 10% depend on your specific use case you may have to get more complicated but for the most part what I cover in this article should be able to help you so let’s start with the model that I have I’ve already created it.

**Read More : **How to make Chatbot in Python.

Read More : Django Admin Full Customization step by step

let’s just get into this diagram that I made so in here:

django queries aboutDescribe each parameter in Django querset

we’re making a simple query for the myModel table so we want to pull out all the information in the database so we have this variable which is gonna hold a return value and we have our myModel models so this is simply the myModel model name so whatever you named your model just make sure you specify that and we’re gonna access the objects attribute once we get that object’s attribute we can simply use the all method and this will return all the information in the database so we’re gonna start with all and then we will go into getting single items filtering that data and go to our command prompt.

Here and we’ll actually start making our queries from here to do this let’s just go ahead and run** Python manage.py shell** and I am in my project file so make sure you’re in there when you start and what this does is it gives us an interactive shell to actually start working with our data so this is a lot like the Python shell but because we did manage.py it allows us to do things a Django way and actually query our database now open up the command prompt and let’s go ahead and start making our first queries.
