Optimizer - 3.3. Datasets - 3.4. Methods - 3.5. Audit 4. Conclusion What is Aequitas Flow? Aequitas Flow is the codename for the latest version of Aequitas, a well-established package for fairness auditing in the ML community. This version extends the package to include experimentation with Fair ML algorithms. Aequitas started as a software to diagnose and alert for disparities in ML models' decisions depending on sensitive attributes, such as race, gender, or age. To achieve this, the package runs a Bias Audit, in which it calculates several metrics across all data groups, determined by the sensitive attributes, and compares them to identify any gap in performance. While some other packages already implement Fair ML methods, they also introduce an overhead of technical knowledge to configure, evaluate, and deploy these models. Because of this, we extended Aequitas to enable users to conduct experiments using a wide variety of fair ML methods from the literature in an intuitive user experience. Aequitas Flow was built on the principles of extensibility and reproducibility: it allows users to incorporate their own datasets and methods in the framework using familiar interfaces of sci-kit-learn and pandas. It ensures their work can be replicated by performin ## FugueSQL: Interoperable Python and Trino for interactive workloads DevFeed: [FugueSQL: Interoperable Python and Trino for interactive workloads]() Original publisher: [Read original article]() Author: Kevin Kho and Cole Bowden Published: 2023-07-27T00:00:00Z Content type: article Language: en Sources: [Trino Blog]() Topics: [Python](), [SQL](), [interoperability](), [pandas](), [Code](), [Programming](), [Back end]() Tags: [backend](), [ecosystem](), [github](), [integration](), [interoperability](), [performance](), [python](), [scale](), [sql](), [testing]() ### AI overview The article recaps a Trino Fest session about FugueSQL, a Python programming model that improves interoperability between Python and SQL.

I have also been playing with Python ever since, with coding exercises during the "Friday 10% time" here at the BBC and on my own time when I have some to spare. I created this playground repository to refresh my Pythonic knowledge that was buried deep inside the funny head of mine. This repo is a mix of material and exercises to keep my Python coding skills sharp. GitHub - simonespa/python-playground: A playground repo for Python I also created a specific playground focused on Data Science and Machine learning. In this playground I practice with libraries such as NumPy, Pandas, Scikit-Learn, TensorFlow (et. all) with a Jupyter Notebook. It also contains notes and summaries of what I learn in forms of README or notebooks. GitHub - simonespa/machine-learning-playground: A playground to practice machine learning, data modelling and visualisation Nothing fancy or ground-breaking, just a couple of playground repos for me to practice and learn at my own pace. The 10% time at the BBC This happens every other Friday and it is about learning. Engineers use this time to learn new technologies and/or languages, discover new approaches and techniques. We can organise the day as we want. It could be a self-paced learning session (reading, watching tutorials, etc.), a day of study for an apprenticeship or a university degree etc., an actual hands-on prototyping session to work on a long-running personal project, or a group collaboration with other like-minded people. There is no limitation to how we plan our day, as long as we keep in mind the end goal.

The article demonstrates reading JSON data, sampling and copying a DataFrame, checking its length and type, examining columns, accessing text values, iterating over them, and converting values to strings. ### Source excerpt As I write this it is 3:45 am and I am playing with Python. I have a small script that looks like this: import pandas as pd DATA_PATH = "data/" filename = "file.json" train_sample_size = 45000 dataset = pd.read_json(os.path.join(DATA_PATH, filename), lines=True) dataset_test = dataset.copy().sample(train_sample_size).reset_index() dataset_head = dataset_test.head(train_sample_size) pdb.set_trace() The pandas library give you a bunch of facilities for looking at data and organizing it into what are called data frames. If you think of pandas as a spreadsheet that you can use programmatically, well, that's not far off. Pandas is widely used for Python data processing and can read data from CSV and JSON formats (among others). If I want to investigate the length of a variable, I can do this: (Pdb) len(dataset) 45648 And if I want to know the type of a variable, I can do this: type(dataset) And if I want to know the columns that Pandas as loaded from the json, I can do this: dataset.columns Index(['tweet_id', 'timestamp_us_eastern', 'author_handle', 'author_screenname', 'authority', 'predicted_gender', 'predicted_language', 'predicted_country', 'predicted_state_or_province', 'predicted_city', 'given_location', 'followers', 'following', 'predicted_sentiment', 'context_notes', 'antisemitic_classification', 'author_bio', 'text', 'is_truncated', 'is_retweet', 'lang', 'Majority Model', 'label'], dtype='object') What this tells me is that I have a dataset variable with a text column that I can access by dataset.text. And then if I want the first 'row' of data in this column, I can do this: (Pdb) dataset.text[0] "Jerry Seinfeld spent a lot of time in Israel's apartheid State supporting the Zionists and giving the bastards credibility.

It explains how Pandas and Matplotlib keep labeled data and graphing in one programming environment, using vmstat output and CSV files as examples. ### Source excerpt I've been using gnuplot since.. like forever. It is one of my best friends in plotting data and discovering what is going on. But for all its greatness, you do tend to run into a wall - once you step outside the things gnuplot is good at, suddenly large heaps of awk, sort, unique and odd shell scripts are required to get to the next level. This is no criticism of gnuplot - it is great for what it is for.
