Google researchers address the challenges of achieving a comprehensive understanding of diverse video content by introducing a novel encoder model, VideoPrism. Existing models in video understanding have struggled with various tasks with complex systems and motion-centric reasoning and demonstrated poor performance across different benchmarks. The researchers aimed to develop a general-purpose video encoder that can…
Quick Success Data Science Learn graphical text analysis with NLTK Sherlock Holmes (by DALL-E3)The Natural Language Tool Kit (NLTK) ships with a fun feature called a dispersion plot that lets you post the location of a word in a text. More specifically, it plots the occurrences of a word versus the number of words from…
Unified vision-language models have emerged as a frontier, blending the visual with the verbal to create models that can interpret images and respond in human language. However, a stumbling block in their development has been ensuring that these models behave consistently across different tasks. The crux of the problem lies in the model’s ability to…
To keep things simple and costs to a minimum ETL Pipeline | Image by authorETL stands for Extract, Transform, and Load. An ETL pipeline is essentially just a data transformation process — extracting data from one place, doing something with it, and then loading it back to the same or a different place. If you…
Using scenario based stress testing to identify medium (2050) and long term (2100) sea level rise risks This project utilizes a scenario based qualitative stress testing approach to identify US coastal census tracts expected to adversely impacted by sea level rise (SLR) in the medium (2050) and long term (2100). One Baseline and two ‘plausible…
First of all, let’s define our hypoparameters. Like in many other metaheuristic algorithms, these variables should be adjusted on the way, and there is no versatile set of values. But let’s stick to these ones: POP_SIZE = 10 #population size MAX_ITER = 30 #the amount of optimization iterations w = 0.2 #inertia weight c1…

If you want to become a skilled data scientist, you should know how to understand and analyze data. And for this statistics is important.
However, learning statistics can feel difficult, especially if you’re not from a math or computer science background. But don't worry. We’ve compiled a list…
When LLMs give us outputs that reveal flaws in human society, can we choose to listen to what they tell us? Photo by Vince Fleming on UnsplashBy now, I’m sure most of you have heard the news about Google’s new LLM*, Gemini, generating pictures of racially diverse people in Nazi uniforms. This little news blip…
