Deep Stream Dynamic Graph Analytics with Grapharis - Massimo Perini
World's toughest and most interesting analysis tasks lie at the intersection of graph data (inter-dependencies in data) and deep learning (inter-dependencies in the model). Classical graph embedding techniques have for years occupied research groups seeking how complex graphs can be encoded into a low-dimensional latent space. Recently, deep learning has dominated the space of embeddings generation due to its ability to automatically generate embeddings given any static graph.
Grapharis is a project that revitalizes the concept of graph embeddings, yet it does so in a real setting were graphs are not static but keep changing over time (think of user interactions in social networks). More specifically, we explored how a system like Flink can be used to simplify both the process of training a graph embedding model incrementally but also make complex inferences and predictions in real time using graph structured data streams. To our knowledge, Grapharis is the first complete data pipeline using Flink and Tensorflow for real-time deep graph learning. This talk will cover how we can train, store and generate embeddings continuously and accurately as data evolves over time without the need to re-train the underlying model.
6On Efficient Retiming of Fixed-Point Circuits
Retiming of digital circuits is conventionally based on the estimates of propagation delays across different paths in the data-flow graphs (DFGs) obtained by discrete component
timing model, which implicitly assumes that operation of a node can begin only after the completion of the operation(s) of its preceding node(s) to obey the data dependence requirement. Such a discrete component timing model very often gives much higher
estimates of the propagation delays than the actuals particularly when the computations in the DFG nodes correspond to fixed point arithmetic operations like additions and multiplications
HDLC & basic protocols
The document discusses High-Level Data Link Control (HDLC), a bit-oriented synchronous data link layer protocol developed by ISO. It describes HDLC's operation modes including Normal Response Mode, Asynchronous Response Mode, and Asynchronous Balanced Mode. The document also covers HDLC frame format, frame classes including unnumbered, supervisory, and information frames, and HDLC protocol operation for link management and data transfer with error and flow control.
Hdlc
HDLC is a bit-oriented protocol that organizes data into frames for transmission between devices over point-to-point or multipoint links. An HDLC frame consists of opening and closing flags bounding address, control, information, and frame check sequence fields. The control field contains sequence numbers for flow and error control. There are three classes of frames: information frames for data, unnumbered frames for link management, and supervisory frames for flow and error control using sequence numbers when piggybacking is not possible.
Stochastic Computing Correlation Utilization in Convolutional Neural Network ...
In recent years, many applications have been implemented in embedded systems and mobile Internet of Things (IoT) devices that typically have constrained resources, smaller power budget, and exhibit "smartness" or intelligence. To implement computation-intensive and resource-hungry Convolutional Neural Network (CNN) in this class of devices, many research groups have developed specialized parallel accelerators using Graphical Processing Units (GPU), Field-Programmable Gate Arrays (FPGA), or Application-Specific Integrated Circuits (ASIC). An alternative computing paradigm called Stochastic Computing (SC) can implement CNN with low hardware footprint and power consumption. To enable building more efficient SC CNN, this work incorporates the CNN basic functions in SC that exploit correlation, share Random Number Generators (RNG), and is more robust to rounding error. Experimental results show our proposed solution provides significant savings in hardware footprint and increased accuracy for the SC CNN basic functions circuits compared to previous work.
HDLC
HDLC is a bit-oriented protocol defined by ISO for point-to-point and multipoint communication over data links. It supports full-duplex communication and provides reliability, efficiency and flexibility. HDLC defines three types of stations - primary, secondary and combined. It uses three frame types - unnumbered, information and supervisory frames. HDLC also specifies three data transfer modes - normal response mode, asynchronous response mode and asynchronous balanced mode. [/SUMMARY]

Neha Agarwal presented two TDMA scheduling algorithms for wireless sensor networks: a node-based algorithm and a level-based algorithm. The node-based algorithm schedules nodes by coloring the network graph and assigning time slots to non-conflicting nodes. The level-based algorithm first obtains a linear network graph and then schedules nodes based on coloring the linear graph. Both algorithms aim to find the smallest conflict-free time frame for all nodes to transmit. Distributed and clustered implementations were also discussed to improve scalability.
Sparse inverse covariance estimation
This document summarizes work on estimating sparse inverse covariance matrices using graphical lasso. It discusses how graphical lasso uses an L1 regularization and coordinate descent algorithms to efficiently estimate sparse inverse covariance matrices. The new GLASSO R package was developed that is 30-4000x faster than existing methods for estimating sparse graphical models on large datasets with thousands of nodes and parameters. Future work aims to apply this approach to even larger datasets where the number of parameters exceeds the number of samples.

This document proposes techniques for automating the management of simulation accuracy in mixed-mode digital VLSI circuit simulation. It addresses the need to efficiently simulate increasingly large and complex circuits while providing guaranteed accuracy. The key techniques presented are:
1) An uncertainty redistribution method to determine the required accuracy for each subcircuit block based on its contribution to overall output delay uncertainty.
2) An iterative simulation approach that starts with low-accuracy analysis and refines accuracy levels using heuristics until simulation convergence is reached.
3) A mixed-mode simulation testbed that implements these accuracy management techniques and allows experiments using different simulator types. Experiments demonstrated the efficiency gains compared to uniform high-accuracy simulation.
PointNet: Deep Learning on Point Sets for 3D Classification and Segmentation
The document discusses deep learning on point sets. Point sets have properties of being unordered, invariant to transformations, and having interactions among points. The PointNet architecture uses three key techniques: 1) a max pooling layer as a symmetric function to aggregate point information, 2) a structure to combine local and global information, and 3) two joint alignment networks to align input points and point features. The architecture provides permutation invariance and is robust to data corruption.
HDLC(High level Data Link Control)
HDLC is a bit-oriented protocol that defines rules for transmitting data between network nodes. It supports full-duplex communication and organizes data into frames sent from a source to a destination. HDLC defines three station types - primary stations control data flow, secondary stations operate under primary control, and combined stations act as both. HDLC uses different frame types and operates in modes like normal response for point-to-point links and asynchronous balanced for communication between combined stations.
Design of arq and hybrid arq protocols for wireless channels using bch codes
This document discusses the design of ARQ and hybrid ARQ protocols for wireless channels using BCH codes. It begins with an introduction to ARQ and FEC schemes for error control. A hybrid ARQ scheme is proposed that combines FEC and ARQ to improve throughput efficiency and reliability over using ARQ alone. Specifically, a type-1 hybrid ARQ protocol is designed using a (1023,923) BCH code that can correct up to 5 errors. Simulation results show that the hybrid ARQ scheme provides higher throughput than basic ARQ schemes, especially at lower SNR values, by correcting some error patterns without retransmission. In conclusion, hybrid ARQ is found to perform better than either ARQ or FEC alone by taking advantage of the strengths of both.

This document summarizes a research paper that proposes using parallel concatenated turbo codes in wireless sensor networks in an adaptive way. The key points are:
1) Turbo codes can achieve near-Shannon limit performance but decoding is complex, making them difficult to implement on energy-constrained sensor nodes.
2) The proposed approach shifts the complex turbo decoding to the base station while sensor nodes implement encoding and basic error correction.
3) At sensor nodes, a parallel concatenated convolutional code (PCCC) circuit encodes data and detects/corrects errors in forwarded packets. This improves energy efficiency and reliability over the wireless sensor network.
Design and Implementation of an Embedded System for Software Defined Radio
In this paper, developing high performance software for demanding real-time embed- ded systems is proposed. This software-based design will enable the software engineers and system architects in emerging technology areas like 5G Wireless and Software Defined Networking (SDN) to build their algorithms. An ADSP-21364 floating point SHARC Digital Signal Processor (DSP) running at 333 MHz is adopted as a platform for an embedded system. To evaluate the proposed embedded system, an implementation of frame, symbol and carrier phase synchronization is presented as an application. Its performance is investigated with an on line Quadrature Phase Shift keying (QPSK) receiver. Obtained results show that the designed software is implemented successfully based on the SHARC DSP which can utilized efficiently for such algorithms. In addition, it is proven that the proposed embedded system is pragmatic and capable of dealing with the memory constraints and critical time issue due to a long length interleaved coded data utilized for channel coding.

Compressive Data Gathering using NACS in Wireless Sensor Network
The document proposes a Neighbor-Aided Compressive Sensing (NACS) scheme for efficient data gathering in wireless sensor networks. NACS exploits both spatial and temporal correlations in sensor data to reduce data transmissions compared to existing compressive sensing models like Kronecker Compressive Sensing (KCS) and Structured Random Matrix (SRM). In NACS, each sensor node sends its raw sensor readings to a uniquely selected nearest neighbor node, which then applies compressive sensing measurements and sends the compressed data to the sink node. Simulation results show NACS achieves better data recovery performance using fewer transmissions than KCS and SRM, improving energy efficiency for data gathering in wireless sensor networks.
IRJET- Enhanced Security using DNA Cryptography
The document proposes a new technique for secure encryption and decryption that combines stream cipher and compressive sensing with DNA encoding and decoding. It discusses using a linear feedback shift register (LFSR) based stream cipher to generate the measurement matrix for compressive sensing. The same stream cipher is then used to encrypt data. DNA encoding represents the encryption key as DNA nucleotide bases (A, C, G, T) according to a lookup table. At the receiver, decryption uses the same key and lookup table to recover the original data. The technique is implemented using Verilog HDL and provides faster encryption speeds and more secure transmission of sensory and medical data compared to traditional methods.

ANALOG MODELING OF RECURSIVE ESTIMATOR DESIGN WITH FILTER DESIGN MODEL
This document summarizes a research paper on implementing a low power design methodology for recursive encoders and decoders. It discusses how recursive coding can achieve better error correction performance at low signal-to-noise ratios compared to other codes. It then describes the design of a recursive decoder that uses the log-MAP algorithm to minimize power consumption. The decoder uses five main computational steps - branch metric calculation, forward metric computation, backward metric computation, log-likelihood ratio calculation, and extrinsic information calculation. It also compares the implementation of four-state and eight-state recursive encoders. The goal of the design is to optimize the power and area of recursive encoders and decoders.

Multiple Dimensional Fault Tolerant Schemes for Crypto Stream Ciphers
This document proposes two fault tolerant schemes for stream ciphers based on Algorithm Based Fault Tolerance (ABFT). The first is a 2-D mesh ABFT scheme that can detect and correct any single error in an n-by-n plaintext matrix with linear computation and bandwidth overhead. It constructs matrices for the plaintext, keystream, and transmitted data with row and column checksums. The second is a 3-D mesh-knight ABFT scheme that can detect and correct up to three errors by adding an extra "knight" checksum dimension. Both schemes use only XOR operations and allow errors to be efficiently located and recovered.
Multiple Dimensional Fault Tolerant Schemes for Crypto Stream Ciphers
To enhance the security and reliability of the widely-used stream ciphers, a 2-D and a 3-D mesh-knight Algorithm Based Fault Tolerant (ABFT) schemes for stream ciphers are developed which can be universally applied to RC4 and other stream ciphers. Based on the ready-made arithmetic unit in stream ciphers, the proposed 2-D ABFT scheme is able to detect and correct any simple error, and the 3-D meshknight ABFT scheme is capable of detecting and correcting up to three errors in an n2 -data matrix with liner computation and bandwidth overhead. The proposed schemes provide one-to-one mapping between data index and check sum group so that error can be located and recovered by easier logic and simple operations.
Low complexity design of non binary ldpc decoder using extended min-sum algor...
This document summarizes a research paper on reducing the computational complexity of non-binary LDPC decoders using an extended min-sum algorithm. It introduces low-density parity check codes and non-binary LDPC codes. It then describes an extended min-sum decoding algorithm and proposes two modifications to the parity check matrix - a lower diagonal matrix and a doubly diagonal matrix - to reduce complexity while maintaining performance. Simulation results on code lengths of 504 and 648 bits show the doubly diagonal matrix achieves the best bit error rate. Analysis finds the lower diagonal matrix has the lowest computational complexity of the approaches.
High Speed Low-Power Viterbi Decoder Using Trellis Code Modulation
Abstract - High speed low power viterbi decoders for trellis code modulation is well known for the delay consumption in underwater communication. In transmission system wireless communication is the transfer of information between two or more points that are not connected by an electrical conductor. WiMAX is the wireless communication standard designed to provide 30 to 40 Mega bits per second data rates. WiMAX as a standards based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL. WiMAX can provide at home or mobile internet access across whole cities or countries. The address generation of WiMAX is carried out by interleaver and deinterleaver. Interleaving is used to overcome correlated channel noise such as burst error or fading. The interleaver/deinterleaver rearranges input data such that consecutive data are spaced apart. The interleaved memory is to improve the speed of access to memory. The viterbi technique reduces the bit error rate and delay using wimax.

MODELLING AND SIMULATION OF 128-BIT CROSSBAR SWITCH FOR NETWORK -ONCHIP
This is widely accepted that Network-on-Chip represents a promising solution for forthcoming complex embedded systems. The current SoC Solutions are built from heterogeneous hardware and Software components integrated around a complex communication infrastructure. The crossbar is a vital component of in any NoC router. In this work, we have designed a crossbar interconnect for serial bit data transfer and 128-parallel bit data transfer. We have shown comparision between power and delay for the serial bit and parallel bit data transfer through crossbar switch. The design is implemented in 0.180 micron TSM technology.The bit rate achived in serial transfer is slow as compared with parallel data transfer. The simulation resuls show that the critical path delay is less for parallel bit data transfer but power dissipation is high.

This paper shows a new technic applicable for the digital devices that are the result of the finite’s
effect precision in the chaotic dynamics used in the coupled technic and the chaotic map’s perturbation
technics used for the generation of a Pseudo-Random Number Generator (PRNGs).The use of the
pseudo- chaotic sequences coupled to the orbit perturbation method in the chaotic logistic map and the
NewPiece-Wise Linear Chaotic Map (NPWLCM). The pseudo random number generator’s originality
proposed from the perturbation of the chaotic recurrence. Furthermore the outputs of the binary sequences
with NPWLCM are reconstructed conventionally with the Bernoulli’s sequences shifts map to change the
shapes with the bitwise permetation then the results in simulation are shown in progress.After being
perturbed, the chaotic system can generate the chaotic binary sequences in uniform distribution and the
statistical properties invulnerable analysis. This generator also has many advantages in the possible useful
applications of spread spectrum digitalimages, such as sensitive secret keys, random uniform distribution
of pixels in Crypto system in secure and synchronize communication.
Iaetsd chaos cdsk communication system
This document proposes and evaluates a new chaotic communication system called Correlation Delay Shift Keying (CDSK). It summarizes the characteristics and advantages of using chaotic signals for communication. It then describes the CDSK system and compares its bit error rate performance using two different chaos maps (Tent map and a newly proposed Boss map) in additive white Gaussian noise and Rayleigh fading channels. The results show that the Boss map provides better bit error rate performance than the Tent map.
Neural network based identification of multimachine power system
In recent years, the golden codes have proven to exhibit a superior performance in a wireless
MIMO (Multiple Input Multiple Output) scenario than any other code. However, a serious
limitation associated with it is its increased decoding complexity. This paper attempts to resolve
this challenge through suitable modification of golden code such that a less complex sphere
decoder could be used without much compromising the error rates. In this paper, a minimum
polynomial equation is introduced to obtain a reduced golden ratio (RGR) number for golden
code which demands only for a low complexity decoding procedure. One of the attractive
approaches used in this paper is that the effective channel matrix has been exploited to perform
a single symbol wise decoding instead of grouped symbols using a sphere decoder with tree
search algorithm. It has been observed that the low decoding complexity of O (q1.5) is obtained
against conventional method of O (q2.5). Simulation analysis envisages that in addition to
reduced decoding, improved error rates is also obtained.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
