Python for Loops: The Pythonic Way

Python for Loops: The Pythonic Way

⋅

Python’s for loop allows you to iterate over the items in a collection, such as lists, tuples, strings, and dictionaries. The for loop syntax declares a loop variable that takes each item from the collection in each iteration. This loop is ideal for repeatedly executing a block of code on each item in the collection. You can also tweak for loops further with features like break, continue, and else. By the end of this tutorial, you’ll understand that: […]

Orthogonal Uplift Learning with Permutation-Invariant Representations for Combinatorial Treatments

⋅

We study uplift estimation for combinatorial treatments. Uplift measures the pure incremental causal effect of an intervention (e.g., sending a coupon or a marketing message) on user behavior, modeled as a conditional individual treatment effect. Many real-world interventions are combinatorial: a treatment is a policy that specifies context-dependent action distributions rather than a single atomic label. Although recent work considers structured treatments, most methods rely on categorical or opaque encodings, limiting robustness and generalization to rare or newly […]

Review: Knight of the Seven Kingdoms brings back that Westeros magic

⋅

HBO has another critically acclaimed hit with A Knight of the Seven Kingdoms, based on George R.R. Martin’s Tales of Dunk and Egg novellas, and it deserves every bit of the praise heaped upon it. The immensely satisfying first season wrapped with last night’s finale, dealing with the tragedy of the penultimate episode and setting the stage for the further adventures of Dunk and Egg. House of the Dragon is a solid series, but Knight of the Seven […]

Meta-Learning and Meta-Reinforcement Learning – Tracing the Path towards DeepMind’s Adaptive Agent

⋅

Humans are highly effective at utilizing prior knowledge to adapt to novel tasks, a capability that standard machine learning models struggle to replicate due to their reliance on task-specific training. Meta-learning overcomes this limitation by allowing models to acquire transferable knowledge from various tasks, enabling rapid adaptation to new challenges with minimal data. This survey provides a rigorous, task-based formalization of meta-learning and meta-reinforcement learning and uses that paradigm to chronicle the landmark algorithms that paved the way […]

MultiModalPFN: Extending Prior-Data Fitted Networks for Multimodal Tabular Learning

⋅

Recently, TabPFN has gained attention as a foundation model for tabular data. However, it struggles to integrate heterogeneous modalities such as images and text, which are common in domains like healthcare and marketing, thereby limiting its applicability. To address this, we present the Multi-Modal Prior-data Fitted Network (MMPFN), which extends TabPFN to handle tabular and non-tabular modalities in a unified manner. MMPFN comprises per-modality encoders, modality projectors, and pre-trained foundation models. The modality projectors serve as the critical […]

The latest scourge of Twitter is AI bots that reply to your tweets with generic, banal commentary slop, often accompanied by a question to “drive engagement” and waste as much of your time as possible. I just found out that the category name for this genre of software is reply guy tools. Amazing. Tags: ai-ethics, twitter, slop, generative-ai, definitions, ai, llms

Quoting Summer Yue

⋅

Nothing humbles you like telling your OpenClaw “confirm before acting” and watching it speedrun deleting your inbox. I couldn’t stop it from my phone. I had to RUN to my Mac mini like I was defusing a bomb. I said “Check this inbox too and suggest what you would archive or delete, don’t action until I tell you to.” This has been working well for my toy inbox, but my real inbox was too huge and triggered compaction.

Tritone substitution

Tritone substitution

⋅

Big moves in roots can correspond to small moves in chords. Imagine the 12 notes of a chromatic scale arranged around the hours of a clock: C at 12:00, C♯ at 1:00, D at 2:00, etc. The furthest apart two notes can be is 6 half steps, just as the furthest apart two times can be is 6 hours. An interval of 6 half steps is called a tritone. That’s a common term in jazz. In classical music […]
