A Cup Of Code

This is fully written by me without any help from AI, except for learning the concepts. This blog covers everything everyone should be aware of in the AI world, and it took me weeks to learn it so I could make it easy for you. To understand the basics of agents and how to build one, check out Part 2 of the Agentic AI series here . Overview In Part 2, we read about the following: How agents remembers past conversations How agents personalize the replies for you History and checkpointing In this blog , we will be targeting how to make AI Agents more reliable and production ready using Harnesses. Limitation of Agents Harnesses target the major limitations of agents i.e. they are single shot and don't validate the results before you give any output to the user. If you ask an agent to write something, it will do that. But it will not validate the results even if you ask it to validate as LLMs are single shot and once they give you a reply, they just stop after first reply. Harness A ha...

This is fully written by me without any help from AI, except for learning the concepts. This blog covers everything everyone should be aware of in the AI world, and it took me weeks to learn it so I could make it easy for you. To understand the basics of agents and how to build one, check out Part 1 of the Agentic AI series here .  Overview In Part 1, we read about the following: What are LLMs and how do they work How LLMs transform into agents to do real-world work Limitations of LLMs and AI Agents In this blog , we will be targeting one of the major limitations of LLM-based agents - memory, persistence, and checkpointing. LLMs are stateless, so they don't remember their past state and chats whenever they are called(through APIs), yet tools like OpenAI ChatGPT, Claude Code, Codex, etc. remember: The whole chat context from the very first message to the current message, even after days or weeks History of all the threads you have worked on with the AI tool The personalized facts ab...

This is fully written by me without any help from AI, except for learning the concepts. This blog consists of all the things that everyone should be aware of in the AI world, which took me weeks to learn to make it easy for you. Overview In the world of AI, LLMs are not sufficient. LLMs are simple(and yet complex) until you convert them to agents. This is where all the powers are unlocked, and LLMs can be used to do anything and everything in the world. This blog explains how a chatbot(or simple LLM) is actually converted into an AI Agent to do real-world, productive things. I'll explain from the basics what LLMs are, how they should be used, and how agents are created, but on a high level: LLMs(or large language models) are models trained(like Gemini, Opus, etc) on a huge amount of data and can be considered as "a brain in a glass jar" that can dictate what to do. Agents(or wrappers) are tools written which used LLMs internally to do real-world tasks. Chatbot - a common...

For Part 1, check this out Designing Distributed File Storage Systems - Explained with Google File System(GFS) Overview: Replication in distributed systems involves the process in which we can have multiple copies of data at various locations to guard against unknown and random hardware failures, hence ensuring the availability of the system as a whole. While considering replication, we have to consider the basic assumption that machines will have uncorrelated failures , otherwise, replication will not help in any way. Replication should be considered or not, the number of replicas, etc all depends on the use case and the amount of inconvenience or how much it will cost you if you lose the data and compute power at a given point in time. Replication is achieved, intuitively , when we have two servers, one primary and a replica server, and we have to keep them in synchronize in a way if the primary server fails at any point in time, the replica server should have everything it needs t...

Part 2: Replication-Explained: Designing Distributed systems Overview: Original paper: The Google File System Authors: Sanjay Ghemawat, Howard Gobioff, and Shun-Tak Leung A distributed file system(DFS) is a file system that allows you to access files stored in multiple hosts distributed across them. In contrast to other data stores like MySQL or NoSQL which can also be made distributed, the data is DFS is stored in raw form and as files instead of a table or a fixed-document format. The use cases where DFS is used are very vast. From storing media content like Youtube videos to Instagram images to blogs like these, anything that can be stored as a file, is big and is not suitable to store in other data stores, DFS is generally a preferred choice for everyone. Key points to consider while designing a DFS: Understanding from the perspective of using a distributed file system, there are some characteristics that need to be considered while choosing the data store and tweaked accordin...

Objective: The objective of this work is to understand automated text anonymization system for protection of personal information of users and after anonymization, should still remain relevant in syntactic and semantics terms, without losing the conveyed meaning of text. Anonymized data can be used in many tasks such as data mining, machine learning, analysis, etc without revealing the identity of entities involved in the creation of data and be useful to improve the accuracy of the applied data analysis tool.   Approach: Beyond simply recognizing entities, variation in the types of documents (e.g., financial or medical) and type of identifying information poses a challenge for automated systems. One common approach is to develop domain specific anonymization tools, where one can utilize knowledge about the structure and information content of documents to construct high quality anonymization models , other is to build general models. As different people have different...

Motivation: Using Machine Learning will not require expert knowledge. All machine learning tasks follow the same basic flow. Difficult to find best fit hyper parameters. Hard to make hand made features. Fun. Automatic Machine Learning in progress: My motivation to write blog on this topic was Google's new project - AutoML . Google's AutoML project focuses on deep learning , a technique that involves passing data through layers of neural networks . Creating these layers is complicated, so Google’s idea was to create AI that could do it for them. There are many other open source projects, like AutoML and Auto-SKLEARN working towards a similar goal. Goal: The goal is to design the perfect machine learning “black box” capable of performing all model selection and hyper-parameter tuning without any human intervention.  AutoML draws on many disciplines of machine learning, prominently including Bayesian optimization - It is a sequential design strategy for gl...
