MISATO: A Machine Learning Dataset of Protein-Ligand Complexes for Structure-based Drug Discovery


In the dynamic field of AI technology, a pressing challenge for the drug discovery (DD) community, especially in structural biology and computational chemistry, is the creation of innovative models finely tuned for drug design. The core challenge lies in accurately and efficiently predicting molecular properties crucial for understanding protein-ligand interactions and optimizing binding affinities, essential for advancing effective drug development initiatives.

In current structural biology and drug design, researchers commonly depend on existing datasets and methods, which have inherent limitations like structural inaccuracies, crystallographic artifacts, and difficulties in accurately capturing the dynamic nature of protein-ligand interactions. Traditional approaches for predicting molecular properties often lack the necessary detail for complex protein-ligand interactions, neglecting the vital role of dynamics and flexibility in understanding binding mechanisms and affinity.

Researchers from the Institute of Structural Biology, Technical University of Munich, Jülich Supercomputing Centre, Helmholtz AI, Cambridge University, Jagiellonian University, and Institute of Computational Biology propose MISATO, marking a transformative shift in drug discovery and structural biology methodologies.

How ‘Chain of Thought’ Makes Transformers Smarter


Large Language Models (LLMs) like GPT-3 and ChatGPT exhibit exceptional capabilities in complex reasoning tasks such as mathematical problem-solving and code generation, far surpassing standard supervised machine learning techniques. The key to unlocking these advanced reasoning abilities lies in the chain of thought (CoT), which refers to the ability of the model to generate intermediate reasoning steps before arriving at the final answer, kind of like how we humans break down a complex problem into smaller steps in our head. This can be achieved through methods like training the model on examples enriched with intermediate reasoning steps or using few-shot prompting to instruct the model to generate a CoT.

Now, you might think that the contents of these intermediate steps is what allows the model to reason better. But interestingly, in this study, the researchers found that even if the intermediate steps are incorrect or completely random, just the act of generating them still helps the model a lot. It’s like the model is being told “Okay, think this through step-by-step” and that alone improves its reasoning ability drastically.

So the researchers wanted to understand why this “chain of thought” approach is so powerful for transformers (the type of model used in GPT-3, etc). They used concepts from circuit complexity theory and adopted the language of computational complexity classes like NC, AC, and TC to analyze this problem.

Essentially, they found that without the chain of thought, transformers are limited to efficiently performing only parallel computations, meaning they can solve problems that can be broken down into independent sub-tasks that can be computed simultaneously.

However, many complex reasoning tasks require inherently serial computations, where one step follows from the previous step. And this is where the chain of thought helps transformers a lot. By generating step-by-step reasoning, the model can perform many more serial computations than it could without CoT.

The researchers proved theoretically that while a basic transformer without CoT can only solve problems up to a certain complexity level, allowing a polynomial number of CoT steps makes transformers powerful enough to solve almost any computationally hard problem, at least from a theoretical perspective.

To back up their theory, they also did some experiments on different arithmetic tasks – ones that can be parallelized and ones that inherently require sequential computations. Sure enough, they found that transformers struggled on the sequential tasks without CoT, but enabling CoT drastically boosted their performance, especially when the transformer model was relatively small/shallow.

In essence, the chain of thought is a simple but powerful trick that vastly increases the reasoning capabilities of transformer models like GPT-3. It allows them to tackle complex tasks requiring sequential logic that parallel models would fail at.

Tsinghua University Researchers Propose ADELIE: Enhancing Information Extraction with Aligned Large Language Models Around Human-Centric Tasks


Information extraction (IE) is a pivotal area of artificial intelligence that transforms unstructured text into structured, actionable data. Despite their expansive capacities, traditional large language models (LLMs) often fail to comprehend and execute the nuanced directives required for precise IE. These challenges primarily manifest in closed IE tasks, where a model must adhere to stringent, pre-defined schemas.

IE tasks compel models to discern and categorize text in formats that align with predefined structures, such as named entity recognition and relation classification. However, existing LLMs typically falter when tasked with the nuanced understanding and alignment necessary for effective IE. Researchers have traditionally employed strategies such as prompt engineering, which involves providing detailed annotations and guidelines to assist LLMs without altering underlying model parameters.

The research community has observed a critical need for a methodology that enhances LLMs’ understanding of structured tasks and improves execution accuracy. In response, researchers from Tsinghua University have introduced a new approach called ADELIE (Aligning large language moDELs on Information Extraction). This approach leverages a specialized dataset, IEInstruct, comprising over 83,000 instances across various IE formats, including triplets, natural language responses, and JSON outputs. 

ADELIE diverges from conventional methods by integrating supervised fine-tuning with an innovative Direct Preference Optimization (DPO) strategy. This blend enables the model to align more closely with the intricacies of human-like IE processing. Initial training involves a mix of IE-specific and generic data, using the LLAMA 2 model over 6,306 gradient steps, which ensures the retention of broad linguistic capabilities alongside specialized IE performance.

Performance metrics reveal that ADELIE models, ADELIESFT and ADELIEDPO, achieve benchmark-setting results. In evaluations against held-out datasets, ADELIESFT shows an average F1 score improvement of 5% over standard LLM outputs in closed IE tasks. The improvements are even more pronounced for open IE, with ADELIE models outperforming state-of-the-art alternatives by 3-4% margins in robustness and extraction accuracy. In the realm of on-demand IE, the models demonstrate a nuanced understanding of user instructions, translating into highly accurate data structuring.

In conclusion, ADELIE’s methodical training and optimization translate into a potent alignment of LLMs with IE tasks, demonstrating that a focused approach to data diversity and instruction specificity can bridge the gap between human expectations and machine performance. This alignment does not compromise the models’ general capabilities, which is often a concern with task-specific tuning. The impressive results across various metrics and task types underscore the potential of ADELIE to set new standards in information extraction, making it a valuable tool for multiple applications, from academic research to real-world data processing.

AI-powered Social Engineering and Phishing Attacks

AI is reshaping the landscape of social engineering and phishing attacks, allowing for highly targeted and personalized campaigns. AI tools analyze vast datasets to identify potential targets, fine-tuning phishing messages that resonate with specific individuals. These messages are increasingly difficult to distinguish from legitimate communication, significantly increasing their effectiveness. The continuous improvement of generative AI models means they can adapt to counteract detection techniques, making traditional defenses less effective. 

Deepfakes and Synthetic Media for Deception

The use of AI-generated deepfakes and synthetic media in cyberattacks presents a growing threat, particularly in political misinformation and personal impersonation. These technologies can create convincing audio and visual content, leading to misinformation or manipulation of public opinion. The sophistication of these tools enables the creation of media that can be nearly impossible to differentiate from genuine content, raising significant concerns for security and misinformation. 

Evolving Malware and Ransomware with AI

AI also enhances malware’s capabilities, including ransomware, making these threats more adaptive, resilient, and difficult to detect. AI-driven malware can analyze its environment and modify its behavior to evade security measures. This includes learning from defensive responses and finding new vulnerabilities without human intervention. The increased use of AI in malware development suggests a future where automated threats can independently orchestrate attacks across networks. 

AI-enhanced Network Intrusions

AI is increasingly used to automate the process of network intrusion, allowing for rapid and sophisticated attacks. By leveraging AI, attackers can quickly analyze vast data to identify vulnerabilities and orchestrate network attacks. These AI-powered tools can mimic normal user behavior to evade detection systems and perform actions such as data theft, system disruption, or deploying further malware. AI-driven network intrusions represent a significant threat because they can operate at a scale and speed that human attackers cannot match. Integrating AI into network attacks necessitates advancements in equally sophisticated AI-driven security measures to effectively detect and neutralize these threats.

AI in Information Warfare

AI’s capabilities are being exploited in information warfare to automate the creation and dissemination of disinformation. This application of AI can influence public opinion, manipulate political outcomes, and destabilize societal cohesion. AI algorithms can generate believable news stories, social media posts, and even fake images or videos, spreading them across platforms where they can be difficult to distinguish from real information. The strategic use of such AI-generated content can profoundly affect public perception and discourse, making it a powerful tool in information warfare. Addressing this challenge requires robust mechanisms to detect AI-generated content and educate the public about the potential for misinformation.

AI for Exploiting IoT Vulnerabilities

The proliferation of IoT devices has expanded the attack surface for cyber threats, and AI is being used to exploit vulnerabilities in these devices. Attackers use AI to automate discovering unsecured IoT devices and deploy botnets or malicious software. This can lead to large-scale attacks, such as distributed denial of service (DDoS), which can impact infrastructure, steal data, or gain unauthorized access to networks. The ability of AI to learn and adapt makes it particularly effective at identifying new vulnerabilities as they emerge, challenging cybersecurity professionals to constantly update defenses.

AI and Cryptographic Attacks

AI is also making waves in cryptography by enabling more effective attacks on cryptographic algorithms. Through machine learning and pattern recognition techniques, AI systems can analyze encrypted data to find vulnerabilities without knowing the underlying encryption key. This can potentially lead to the decryption of sensitive data without authorization. The evolving capability of AI to break cryptographic protections faster than ever poses a significant threat to the security of data transmissions and stored information, urging the development of more resilient cryptographic methods that can withstand AI-driven attacks.

Hugging Face Introduces the Open Leaderboard for Hebrew LLMs


Hebrew is considered a low-resource language in AI. It has a sophisticated root and pattern system and is a morphologically rich language. Prefixes, suffixes, and infixes are added to words to change their meaning and tense or produce plurals, among other things. Words are constructed from roots. The occurrence of several legitimate word forms derived from a single root might result from this complexity, rendering conventional tokenization techniques—which were meant for morphologically simpler languages—ineffective. Because of this, current language models could find it difficult to interpret and process Hebrew’s subtleties correctly, which emphasizes the need for benchmarks that consider these particular linguistic characteristics.

LLM research in Hebrew is not just a niche area but a crucial field that requires specialized benchmarks to address the linguistic peculiarities and subtleties of the language. A new Hugging Face study is set to revolutionize this field with its ground-breaking initiative: the brand-new open LLM scoreboard. This scoreboard, designed to assess and improve Hebrew language models, is not just another tool but a significant step towards enhancing our understanding and processing of Hebrew’s complexities. By offering strong assessment metrics on language-specific activities and encouraging an open community-driven improvement of generative language models in Hebrew, this leaderboard is poised to close this gap.

The Hugging Face team uses the Demo Leaderboard template, and it draws inspiration from the Open LLM Leaderboard. Submittable models are automatically deployed via HuggingFace’s Inference Endpoints and assessed via literal library-managed API queries. The environment setup was the only complicated part of the implementation; the rest of the code worked as intended.

The Hugging Face team has created four essential datasets to evaluate language models on their comprehension and production of Hebrew, independent of their performance in other languages. These benchmarks assess the models using a few-shot prompt format, which makes sure the models can adjust and react appropriately even in situations with little context. They are listed in the following order:

Answering a Hebrew Question: This assignment assesses a model’s comprehension and ability to accurately retrieve responses based on context, particularly emphasizing understanding and processing information presented in Hebrew. The model’s understanding of Hebrew syntax and semantics is assessed using straightforward question-and-answer formats.

Sentiment Accuracy: This benchmark tests the model’s capacity to identify and decipher sentiments in Hebrew text. It evaluates the model’s accuracy in using language clues to identify positive, negative, or neutral statements.

The Winograd Schema Problem: The exercise’s purpose is to assess the model’s comprehension of Hebrew contextual ambiguity and pronoun resolution. It also assesses the model’s capacity to accurately distinguish pronouns in difficult sentences using common sense and logical reasoning.

Translation: The model’s ability to translate between Hebrew and English is evaluated in this test. It assesses the model’s proficiency in multilingual translation tasks by evaluating linguistic accuracy, fluency, and the capacity to maintain meaning across languages.

The team believes that this new leaderboard will serve as more than just a measuring tool, inspiring the Israeli tech community to identify and close the gaps in Hebrew language technology research. They hope to encourage the creation of models that are both linguistically and culturally varied by offering thorough, targeted evaluations. This will open the door for innovations that respect the diversity of the Hebrew language.

Researchers from Mahidol University introduced a breakthrough known as ZleepAnlystNet, which presents a sophisticated deep-learning framework designed specifically for sleep stage classification. This model utilizes a ‘separating training’ method, where individual components are trained separately to enhance their specific abilities to recognize sleep stages. The system incorporates fifteen convolutional neural networks (CNNs) for feature extraction, each tailored to capture different aspects of the EEG signals and a bidirectional long-short-term memory (BiLSTM) network for sequence classification.

The efficacy of ZleepAnlystNet is notable, with the model achieving an overall accuracy of 87.02%, a macro F1 score (MF1) of 82.09%, and a kappa coefficient of 0.8221, indicating excellent agreement with standard sleep stage scoring. This performance significantly improved over previous models, which often struggled with specific stages like N1, where ZleepAnlystNet manages a per-class F1 score of 54.23%. The model’s ability to consistently identify other stages like Wake (W), N2, N3, and rapid eye movement (REM) with F1 scores of 90.34%, 89.53%, 88.96%, and 87.40% respectively, also stands out.

Cross-dataset validation further illustrates the model’s robustness, showing strong performance metrics even when applied to external datasets, demonstrating its potential for widespread clinical use. The training approach, which isolates and optimizes different model components, has proven crucial in achieving these results. This method also allows for precise adjustments to the model’s architecture, ensuring each part performs optimally without compromising the system’s overall effectiveness.

In conclusion, ZleepAnlystNet represents an advancement in sleep research, offering a powerful tool for accurately and efficiently classifying sleep stages. Its development marks a step forward in the automation of sleep analysis and sets a new standard for integrating deep learning technologies in medical diagnostics. By reducing dependency on manual scoring and increasing reliability, this model paves the way for better understanding and treatment of sleep-related disorders, promising to profoundly impact the field of sleep medicine.
